This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
Being exposed to x-rays can increase the risk of uterine sarcoma. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for uterine sarcoma include the following: - Past treatment with radiation therapy to the pelvis. - Treatment with tamoxifen for breast cancer. If you are taking this drug, have a pelvic exam every year and report any vaginal bleeding (other than menstrual bleeding) as soon as possible.
This condition is rare, affecting 1 in 250,000 to 1 million people worldwide. Alkaptonuria is more common in certain areas of Slovakia (where it has an incidence of about 1 in 19,000 people) and in the Dominican Republic.

Medicare is a federal health insurance program for people - age 65 and older - under age 65 with certain disabilities who have been receiving Social Security disability benefits for a certain amount of time (24 months in most cases) - of any age who have End-Stage Renal Disease (ESRD), which is permanent kidney failure requiring dialysis or a transplant. age 65 and older under age 65 with certain disabilities who have been receiving Social Security disability benefits for a certain amount of time (24 months in most cases) of any age who have End-Stage Renal Disease (ESRD), which is permanent kidney failure requiring dialysis or a transplant. Medicare helps with the cost of health care, but it does not cover all medical expenses.
Summary : Cholesterol is a waxy, fat-like substance that occurs naturally in all parts of the body. Your body needs some cholesterol to work properly. But if you have too much in your blood, it can combine with other substances in the blood and stick to the walls of your arteries. This is called plaque. Plaque can narrow your arteries or even block them. High levels of cholesterol in the blood can increase your risk of heart disease. Your cholesterol levels tend to rise as you get older. There are usually no signs or symptoms that you have high blood cholesterol, but it can be detected with a blood test. You are likely to have high cholesterol if members of your family have it, if you are overweight or if you eat a lot of fatty foods. You can lower your cholesterol by exercising more and eating more fruits and vegetables. You also may need to take medicine to lower your cholesterol. NIH: National Heart, Lung, and Blood Institute
T-cell immunodeficiency, congenital alopecia, and nail dystrophy results from mutations in the FOXN1 gene. This gene provides instructions for making a protein that is important for development of the skin, hair, nails, and immune system. Studies suggest that this protein helps guide the formation of hair follicles and the growth of fingernails and toenails. The FOXN1 protein also plays a critical role in the formation of the thymus, which is a gland located behind the breastbone where T cells mature and become functional. Researchers suspect that the FOXN1 protein is also involved in the development of the central nervous system, although its role is unclear. Mutations in the FOXN1 gene prevent cells from making any functional FOXN1 protein. Without this protein, hair and nails cannot grow normally. A lack of FOXN1 protein also prevents the formation of the thymus. When this gland is not present, the immune system cannot produce mature, functional T cells to fight infections. As a result, people with T-cell immunodeficiency, congenital alopecia, and nail dystrophy develop recurrent serious infections starting early in life.
ACD/MPV is usually not inherited, and most affected people have no history of the disorder in their family. The genetic changes associated with this condition usually occur during the formation of reproductive cells (eggs and sperm) or in early fetal development. When the condition is caused by a FOXF1 gene mutation or deletion, one altered or missing gene in each cell is sufficient to cause the disorder. Individuals with ACD/MPV do not pass the genetic change on to their children because they do not live long enough to reproduce. A few families have been identified in which more than one sibling has ACD/MPV. It is not clear how ACD/MPV is inherited in these families because no genetic changes have been identified.
Landau-Kleffner syndrome (LKS) is a rare, childhood neurological disorder characterized by the sudden or gradual development of aphasia (the inability to understand or express language) and an abnormal electro-encephalogram (EEG). LKS affects the parts of the brain that control comprehension and speech. The disorder usually occurs in children between the ages of 5 and 7 years. Typically, children with LKS develop normally but then lose their language skills for no apparent reason. While many of the affected individuals have seizures, some do not. The disorder is difficult to diagnose and may be misdiagnosed as autism, pervasive developmental disorder, hearing impairment, learning disability, auditory/verbal processing disorder, attention deficit disorder, childhood schizophrenia, or emotional/behavioral problems.
Summary : Pests live where they are not wanted or cause harm to crops, people, or animals. Pesticides can help get rid of them. Pesticides are not just insect killers. They also include chemicals to control weeds, rodents, mildew, germs, and more. Many household products contain pesticides. Pesticides can protect your health by killing germs, animals, or plants that could hurt you. However, they can also be harmful to people or pets. You might want to try non-chemical methods first. If you do need a pesticide, use it correctly. Be especially careful around children and pets. Proper disposal of pesticides is also important - it can help protect the environment. Biologically-based pesticides are becoming more popular. They often are safer than traditional pesticides. Environmental Protection Agency
Macrodactyly of the hand is a rare condition in which a person's fingers are abnormally large due to the overgrowth of the underlying bone and soft tissue. This condition is congenital, meaning that babies are born with it. Although babies are born with the condition, macrodactyly is usually not inherited. Most of the time, only one hand is affected, but usually more than one finger is involved. Macrodactyly may also coexist with syndactyly, a condition in which two fingers are fused together. Although it is a benign condition, macrodactyly is deforming and can look cosmetically displeasing. Surgery, usually involving multiple procedures, can help the problem.
How is Nance-Horan syndrome inherited? Nance-Horan syndrome is inherited as an X-linked dominant trait. In X-linked dominant inheritance, both males and females can be affected by a condition. However, affected males tend to have more severe features than females. X-linked conditions result from mutations of a gene located on an X chromosome. Females have two X chromosomes, but males have one X chromosome and one Y chromosome. In females, disease traits resulting from the abnormal copy of a gene on one X chromosome can be 'masked' by the normal copy of the gene on the other X chromosome. Because only one functioning X chromosome is required in males and females, one of the X chromosomes in each cell of a female is essentially 'turned off,' usually in a random pattern (X chromosome inactivation). Therefore, if the X chromosome with the gene mutation is activated in some cells, female carriers may have some mild features of the disorder. However, since males only have one X chromosome, they will likely fully express a condition if they inherit a gene mutation that is located on the X chromosome.
48,XXYY syndrome is estimated to affect 1 in 18,000 to 50,000 males.
Immunotactoid glomerulopathy, also known as glomerulonephritis with organized monoclonal microtubular immunoglobulin deposits (GOMMID), is a very uncommon cause of glomerular disease. It is related to a similar disease known as fibrillary glomerulopathy, which is more common. Both disorders probably result from deposits derived from immunoglobulins, but in most cases the cause is idiopathic (unknown). On electron microscopy, immunotactoid glomerulopathy is characterized by the formation of microtubules which are much larger than the fibrils observed in fibrillary glomerulonephritis (30 to 50 versus 16 to 24 nm in diameter). The signs and symptoms include blood (hematuria) and protein (proteinuria) in the urine, kidney insufficiency and high blood pressure. Both fibrillary glomerulonephritis and immunotactoid glomerulopathy have been associated with hepatitis C virus infection and with malignancy and autoimmune disease. Also, patients with immunotactoid glomerulopathy have a greater risk to have chronic lymphocytic leukemia and B cell lymphomas and should be screened for all of these conditions. Treatment is generally determined by the severity of the kidney problems.
Mutations in the MAN2B1 gene cause alpha-mannosidosis. This gene provides instructions for making the enzyme alpha-mannosidase. This enzyme works in the lysosomes, which are compartments that digest and recycle materials in the cell. Within lysosomes, the enzyme helps break down complexes of sugar molecules (oligosaccharides) attached to certain proteins (glycoproteins). In particular, alpha-mannosidase helps break down oligosaccharides containing a sugar molecule called mannose. Mutations in the MAN2B1 gene interfere with the ability of the alpha-mannosidase enzyme to perform its role in breaking down mannose-containing oligosaccharides. These oligosaccharides accumulate in the lysosomes and cause cells to malfunction and eventually die. Tissues and organs are damaged by the abnormal accumulation of oligosaccharides and the resulting cell death, leading to the characteristic features of alpha-mannosidosis.
Is genetic testing available for Robinow syndrome? Genetic testing for autosomal recessive Robinow syndrome and autosomal dominant Robinow syndrome is available. However, not all people diagnosed with either type of Robinow syndrome have mutations in the genes known to cause these conditions. In these cases, the cause remains unknown. Carrier testing for autosomal recessive Robinow syndrome is possible if the disease-causing mutations have been identified in an affected family member. The Genetic Testing Registry (GTR) provides information about the genetic tests for Robinow syndrome. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
When present, the tumor and cancer are treated first, followed by efforts to decrease the autoimmune response -- either through steroids such as cortisone or prednisone, high-dose intravenous immunoglobulin, or irradiation. Plasmapheresis, a process that cleanses antibodies from the blood, may ease symptoms in people with paraneoplastic disorders that affect the peripheral nervous system. Speech and physical therapy may help individuals regain some functions.
This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Most cases result from new mutations in the gene and occur in people with no history of the disorder in their family. In a small number of cases, an affected person inherits the mutation from one affected parent.
What are the signs and symptoms of White sponge nevus of cannon? The Human Phenotype Ontology provides the following list of signs and symptoms for White sponge nevus of cannon. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Abnormality of metabolism/homeostasis - Autosomal dominant inheritance - Oral leukoplakia - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.
As with any surgery, cataract surgery poses risks such as infection and bleeding. Before cataract surgery, your doctor may ask you to temporarily stop taking certain medications that increase the risk of bleeding during surgery. After surgery, you must keep your eye clean, wash your hands before touching your eye, and use the prescribed medications to help minimize the risk of infection. Serious infection can result in loss of vision. Cataract surgery slightly increases your risk of retinal detachment. Other eye disorders, such as nearsightedness, can further increase your risk of retinal detachment after cataract surgery. A retinal detachment causes no pain. Early treatment for retinal detachment often can prevent permanent loss of vision. The longer the retina stays detached, the less likely you will regain good vision once you are treated. Even if you are treated promptly, some vision may be lost. Talk to your eye care professional about these risks. Make sure cataract surgery is right for you.
The NINDS conducts and supports an extensive research program on seizures and seizure-related disorders. Much of this research is aimed at increasing scientific understanding of these disorders and finding ways to prevent, treat, and potentially cure them.
How is Klinefelter syndrome diagnosed? A diagnosis of Klinefelter syndrome is often suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis. This generally includes a chromosomal analysis (called a karyotype). It is also possible to diagnosis Klinefelter syndrome before birth through chorionic villous sampling or amniocentesis.
What causes sideroblastic anemia? The exact cause of sideroblastic anemia in many patients remains unknown. Reversible sideroblastic anemia can be caused by alcohol, isoniazid, pyrazinamide, cycloserine (a prescription antibiotic that may cause anemia, peripheral neuritis, or seizures by acting as a pyridoxine antagonist or increasing excretion of pyridoxine), chloramphenicol, or copper deficiency. The hereditary forms may be passed through families in autosomal recessive, autosomal dominant, or X-linked patterns.
- Simple kidney cysts are abnormal, fluid-filled sacs that form in the kidneys. - Simple kidney cysts usually do not cause symptoms or harm the kidneys. - Most simple kidney cysts are found during imaging tests done for other reasons. - Treatment is not needed for simple kidney cysts that do not cause any symptoms. - Simple kidney cysts that are causing symptoms or blocking the flow of blood or urine through the kidney may need to be treated using sclerotherapy or surgery.
What causes juvenile amyotrophic lateral sclerosis? Juvenile amyotrophic lateral sclerosis (ALS) is often genetic and may be caused by mutations in the ALS2 or SETX genes. In some cases the underlying gene abnormality cannot be determined. Juvenile ALS may be inherited in an autosomal dominant (as in ALS type 4) or autosomal recessive (as in ALS type 2) fashion.
You can keep your nervous system healthy by taking these steps: - Eat healthy meals and follow the meal plan that you and your doctor or dietitian have worked out. - If you drink alcoholic beverages, limit your intake to no more than one drink per day for women and two drinks per day for men. Drinking too many alcoholic beverages can make nerve damage worse. More information is provided in the NIDDK health topic, What I need to know about Eating and Diabetes.

Glucose 6 phosphate dehydrogenase (G6PD) deficiency is a hereditary condition in which red blood cells break down (hemolysis) when the body is exposed to certain foods, drugs, infections or stress. This condition occurs when a person is missing or doesn't have enough glucose-6-phosphate dehydrogenase, an enzyme which helps red blood cells work properly. G6PD deficiency is more likely to occur in males, particularly African Americans, and those from certain parts of Africa, Asia, and the Mediterranean. This condition is inherited in an X-linked recessive manner and is caused by mutations in the G6PD gene. Treatment may involve medicines to treat an infection, stopping drugs that are causing red blood cell destruction, and/or transfusions, in some cases.
Agenesis of the dorsal pancreas describes a congenital malformation of the pancreas in which either the entire dorsal pancreas or part of the dorsal pancreas fails to develop (complete agenesis or partial agenesis, respectively). Some individuals experience no symptoms, while others may develop hyperglycemia, diabetes mellitus, bile duct obstruction, abdominal pain, pancreatitis, or other conditions. Hyperglycemia has been shown to be present in approximately 50% of affected individuals. The cause of agenesis of the dorsal pancreas is currently not well understood. It may occur in individuals with no history of the condition in the family (sporadically) and in some cases, autosomal dominant or X-linked dominant inheritance has been suggested. It has also been reported to occur with very rare conditions including polysplenia and polysplenia/heterotaxy syndrome.
Peters plus syndrome is a genetic condition characterized by abnormalities of the front part of the eye called the anterior chamber, short stature, cleft lip with or without cleft palate, and distinctive facial features. The most common eye abnormality is Peters anomaly which involves the thinning and clouding of the cornea and attachment of the iris to the cornea causing blurred vision. Other eye abnormalities such as glaucoma and cataracts are common. The severity of symptoms may vary from person to person. The only gene that has been associated with Peters plus syndrome is B3GALTL. The syndrome is inherited in an autosomal recessive fashion. Treatment varies based on the severity of the symptoms; however, regular appointments with an ophthalmologist and avoidance of agents that increase the risk of glaucoma (e.g., corticosteroids) is recommended.
How might aceruloplasminemia be diagnosed? When a person has more than one of the following symptoms, aceruloplasminemia should be suspected: Diabetes mellitus Retinal degeneration Anemia Movement disorder Diagnosis can be further supported by MRI and pathology results demonstrating iron deposition in the body. People with aceruloplasminemia tend to have low serum copper (<10 ug/dL), low serum iron (< 45 ug/dL), high serum ferritin (850-4000 ng/mL) and absent serum ceruloplasmin concentration. Patients also tend to demonstrate altered serum ceruloplasmin ferroxidase activity. Genetic testing is available on a research basis.
Your esophagus is the tube that carries food from your mouth to your stomach. Gastroesophageal reflux disease (GERD) happens when a muscle at the end of your esophagus does not close properly. This allows stomach contents to leak back, or reflux, into the esophagus and irritate it. You may feel a burning in the chest or throat called heartburn. Sometimes, you can taste stomach fluid in the back of the mouth. If you have these symptoms more than twice a week, you may have GERD. You can also have GERD without having heartburn. Your symptoms could include a dry cough, asthma symptoms, or trouble swallowing. Anyone, including infants and children, can have GERD. If not treated, it can lead to more serious health problems. In some cases, you might need medicines or surgery. However, many people can improve their symptoms by - Avoiding alcohol and spicy, fatty or acidic foods that trigger heartburn - Eating smaller meals - Not eating close to bedtime - Losing weight if needed - Wearing loose-fitting clothes NIH: National Institute of Diabetes and Digestive and Kidney Diseases
The NINDS supports research on conditions such as neurogenic orthostatic hypotension aimed at increasing scientific understanding of the condition and finding ways to treat and prevent it.
This condition is inherited in an autosomal recessive pattern, which means both copies of the gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition.
Episodic ataxia refers to a group of related conditions that affect the nervous system and cause problems with movement. It is characterized by episodes of poor coordination and balance (ataxia). During these episodes, many people also experience dizziness (vertigo), nausea and vomiting, migraine headaches, blurred or double vision, slurred speech, and ringing in the ears (tinnitus). Seizures, muscle weakness, and paralysis affecting one side of the body (hemiplegia) may also occur during attacks. Episodes of ataxia and other symptoms can begin anytime from early childhood to adulthood, with the frequency of attacks ranging from several per day to one or two per year. There are at least seven types of episodic ataxia, designated type 1 through type 7, which are distinguished by their signs and symptoms, age of onset, length of attacks, and, when known, genetic cause. Only types 1 and 2 have been identified in more than one family; episodic ataxia type 2 is the most common form of the condition.
Facioscapulohumeral muscular dystrophy is a disorder characterized by muscle weakness and wasting (atrophy). This condition gets its name from the areas of the body that are affected most often: muscles in the face (facio-), around the shoulder blades (scapulo-), and in the upper arms (humeral). The signs and symptoms of facioscapulohumeral muscular dystrophy usually appear in adolescence. However, the onset and severity of the condition varies widely. Facioscapulohumeral muscular dystrophy results from a deletion of genetic material from a region of DNA known as D4Z4. This region is located near one end of chromosome 4. It is inherited in an autosomal dominant pattern.
If you think you might be sick with nocardiosis, talk to your doctor. He or she can help find out if you have the disease by performing tests that can identify the bacteria that causes nocardiosis. Testing may involve taking tissue samples from the part of the body that is infected. Tissue samples may include the: - Brain - Skin - Lungs (or other parts of the lower airways) - Mucus from the lower airways
What causes Currarino triad? Currarino triad is caused by mutations in the MNX1 gene in nearly all familial and 30% of sporadic cases. These mutations in the gene are called loss of function mutations because the gene can no longer produce working (functional) protein. Less frequently, a complex phenotype of Currarino triad can be caused by microdeletions of 7q containing MNX1 (the long arm of chromosome 7 is missing a small piece of DNA which includes MNX1 and other genes).

A predisposition to Kawasaki disease appears to be passed through generations in families, but the inheritance pattern is unknown. Children of parents who have had Kawasaki disease have twice the risk of developing the disorder compared to the general population. Children with affected siblings have a tenfold higher risk.
Generally, prognosis for individuals with whiplash is good. The neck and head pain clears within a few days or weeks. Most patients recover within 3 months after the injury, however, some may continue to have residual neck pain and headaches.
Mutations in the PRSS1 gene cause most cases of hereditary pancreatitis. The PRSS1 gene provides instructions for making an enzyme called cationic trypsinogen. This enzyme is produced in the pancreas and helps with the digestion of food. When cationic trypsinogen is needed, it is released (secreted) from the pancreas and transported to the small intestine, where it is cut (cleaved) into its working or active form called trypsin. When digestion is complete and trypsin is no longer needed, the enzyme is broken down. Some PRSS1 gene mutations that cause hereditary pancreatitis result in the production of a cationic trypsinogen enzyme that is prematurely converted to trypsin while it is still in the pancreas. Other mutations prevent trypsin from being broken down. These changes result in elevated levels of trypsin in the pancreas. Trypsin activity in the pancreas can damage pancreatic tissue and can also trigger an immune response, causing inflammation in the pancreas. It is estimated that 65 to 80 percent of people with hereditary pancreatitis have mutations in the PRSS1 gene. The remaining cases are caused by mutations in other genes, some of which have not been identified.

In these cases, the sign or symptom may be rare or common.
What causes Denys-Drash syndrome? Denys-Drash syndrome is caused by mutations in the WT1 gene. This gene provides instructions for making a protein (the WT1 protein) that regulates the activity of other genes by attaching (binding) to specific regions of DNA. The WT1 protein plays a role in the development of the kidneys and gonads (ovaries in females and testes in males) before birth. The WT1 gene mutations that cause Denys-Drash syndrome lead to the production of an abnormal protein that cannot bind to DNA. As a result, the activity of certain genes is unregulated, which impairs the development of the kidneys and reproductive organs. Abnormal development of these organs leads to diffuse glomerulosclerosis (where scar tissue forms throughout glomeruli, the tiny blood vessels in the kidney that filter waste from blood) and gonadal dysgenesis, which are characteristic features of Denys-Drash syndrome. The abnormal gene activity caused by the loss of normal WT1 protein also increases the risk of developing Wilms tumor in affected individuals.
How might mosaic trisomy 14 be treated? Treatment for signs and symptoms of mosaic trisomy 14 focuses on the specific features present in each individual. Infants with congenital heart defects may need surgery or other therapies to alleviate symptoms and correct heart malformations. Respiratory infections should be treated aggressively and early. Some infants and children with the condition may need surgical repair of certain craniofacial, genital, or other abnormalities. Early intervention may be important in ensuring that children with the reach their potential. Special services that may be beneficial include special education, physical therapy, and/or other medical, social, and/or vocational services.
Is tracheoesophageal fistula inherited? In most cases, tracheoesophageal fistula (TEF) is not inherited and there is only one affected person in a family. When TEF is isolated (i.e. does not occur with any other abnormalities), it is considered a multifactorial condition (caused by a combination of various genetic and environmental factors). However, in most isolated cases, no specific genetic changes or environmental factors have been proven to cause the condition. When TEF occurs as a feature of a specific genetic syndrome or chromosome abnormality, it may follow the inheritance pattern and recurrence risk for the underlying condition. In these cases, it may be caused by changes in single genes or chromosomes, or it may be multifactorial.
Pulmonary alveolar microlithiasis is a disorder in which tiny fragments (microliths) of calcium phosphate gradually accumulate in the small air sacs (alveoli) of the lungs. These deposits eventually cause widespread damage to the alveoli and surrounding lung tissue (interstitial lung disease). People with this disorder may also develop a persistent cough and difficulty breathing (dyspnea), especially during physical exertion. Chest pain that worsens when coughing, sneezing, or taking deep breaths is another common feature. People with pulmonary alveolar microlithiasis may also develop calcium phosphate deposits in other organs and tissue of the body. Though the course of the disease can be variable, many cases slowly progress to lung fibrosis, respiratory failure, or cor pulmonale. The only effective therapy is lung transplantation. In some cases, pulmonary alveolar microlithiasis is caused by mutations in the SLC34A2 gene and inherited in an autosomal recessive manner.

Monilethrix is a condition that affects hair growth. Its most characteristic feature is that individual strands of hair have a beaded appearance like the beads of a necklace. The name monilethrix comes from the Latin word for necklace (monile) and the Greek word for hair (thrix). Noticeable when viewed under a microscope, the beaded appearance is due to periodic narrowing of the hair shaft. People with monilethrix also have sparse hair growth (hypotrichosis) and short, brittle hair that breaks easily. Affected individuals usually have normal hair at birth, but the hair abnormalities develop within the first few months of life. In mild cases of monilethrix, only hair on the back of the head (occiput) or nape of the neck is affected. In more severe cases, hair over the whole scalp can be affected, as well as pubic hair, underarm hair, eyebrows, eyelashes, or hair on the arms and legs. Occasionally, the skin and nails are involved in monilethrix. Some affected individuals have a skin condition called keratosis pilaris, which causes small bumps on the skin, especially on the scalp, neck, and arms. Affected individuals may also have abnormal fingernails or toenails.
The prevalence of monilethrix is unknown.

This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder.
Researchers have not found that eating, diet, and nutrition play a role in causing inguinal hernias. A person with an inguinal hernia may be able to prevent symptoms by eating high-fiber foods. Fresh fruits, vegetables, and whole grains are high in fiber and may help prevent the constipation and straining that cause some of the painful symptoms of a hernia. The surgeon will provide instructions on eating, diet, and nutrition after inguinal hernia surgery. Most people drink liquids and eat a light diet the day of the operation and then resume their usual diet the next day.
Although the exact incidence of Tourette syndrome is uncertain, it is estimated to affect 1 to 10 in 1,000 children. This disorder occurs in populations and ethnic groups worldwide, and it is more common in males than in females.
Hajdu-Cheney syndrome is a rare disease; its prevalence is unknown. Fewer than 100 affected individuals have been described in the medical literature.

A UTI is an infection in the urinary tract. Infections are caused by microbesorganisms too small to be seen without a microscope. Bacteria * are the most common cause of UTIs. Normally, bacteria that enter the urinary tract are quickly removed by the body before they cause symptoms. But sometimes bacteria overcome the bodys natural defenses and cause infection. *See the Pronunciation Guide for tips on how to say the underlined words.
Dementia with Lewy bodies (DLB) is one of the most common types of progressive dementia. The central features of DLB include progressive cognitive decline, fluctuations in alertness and attention, visual hallucinations, and parkinsonian motor symptoms, such as slowness of movement, difficulty walking, or rigidity. People may also suffer from depression. The symptoms of DLB are caused by the build-up of Lewy bodies accumulated bits of alpha-synuclein protein -- inside the nuclei of neurons in areas of the brain that control particular aspects of memory and motor control. Researchers dont know exactly why alpha-synuclein accumulates into Lewy bodies or how Lewy bodies cause the symptoms of DLB, but they do know that alpha-synuclein accumulation is also linked to Parkinson's disease, multiple system atrophy, and several other disorders, which are referred to as the "synucleinopathies." The similarity of symptoms between DLB and Parkinsons disease, and between DLB and Alzheimers disease, can often make it difficult for a doctor to make a definitive diagnosis. In addition, Lewy bodies are often also found in the brains of people with Parkinson's and Alzheimers diseases. These findings suggest that either DLB is related to these other causes of dementia or that an individual can have both diseases at the same time. DLB usually occurs sporadically, in people with no known family history of the disease. However, rare familial cases have occasionally been reported.
Noonan syndrome is a genetic disorder that causes abnormal development of multiple parts of the body. Features of Noonan syndrome may include a distinctive facial appearance, short stature, a broad or webbed neck, congenital heart defects, bleeding problems, skeletal malformations, and developmental delay. Noonan syndrome may be caused by mutations in any one of several genes including the PTPN11, KRAS, RAF1, SOS1, NRAS and BRAF genes. It is sometimes referred to as a specific subtype based on the responsible gene in an affected person. Noonan syndrome is typically inherited in an autosomal dominant manner but many cases are due to a new mutation and are not inherited from an affected parent.
This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder.
What causes CREST syndrome? In people with CREST syndrome, the immune system appears to stimulate cells called fibroblasts to produce excess amounts of collagen. Normally, fibroblasts synthesize collagen to help heal wounds, but in this case, the protein is produced even when it's not needed, forming thick bands of connective tissue around the cells of the skin, blood vessels and in some cases, the internal organs. Although an abnormal immune system response and the resulting production of excess collagen appears to be the main cause of limited scleroderma, researchers suspect that other factors may play a role, including: genetic factors, pregnancy, hormones, and environmental factors.
Hypoglycemia causes symptoms such as - hunger - shakiness - nervousness - sweating - dizziness or light-headedness - sleepiness - confusion - difficulty speaking - anxiety - weakness Hypoglycemia can also happen during sleep. Some signs of hypoglycemia during sleep include - crying out or having nightmares - finding pajamas or sheets damp from perspiration - feeling tired, irritable, or confused after waking up
Indigestion can be caused by a condition in the digestive tract such as gastroesophageal reflux disease (GERD), peptic ulcer disease, cancer, or abnormality of the pancreas or bile ducts. If the condition improves or resolves, the symptoms of indigestion usually improve. Sometimes a person has indigestion for which a cause cannot be found. This type of indigestion, called functional dyspepsia, is thought to occur in the area where the stomach meets the small intestine. The indigestion may be related to abnormal motilitythe squeezing or relaxing actionof the stomach muscle as it receives, digests, and moves food into the small intestine.
What treatment might be available for someone who has had recurrence of gigantomastia following a breast reduction? Breast reduction with or without hormonal therapy is often the first line of treatment for women who have gigantomastia. However, recurrence of gigantomastia may occur, requiring a second breast reduction procedure or mastectomy. Mastectomy might be recommended following recurrence of gigantomastia after breast reduction, especially in those patients who have gigantomastia associated with puberty or pregnancy. It is important to discuss this information with a health care provider in order to determine what treatment might be appropriate.
Your LDL cholesterol goal level depends on your risk for developing heart disease or having a heart attack at the time you start treatment. Major risk factors that affect your LDL goal include - cigarette smoking - high blood pressure (140/90 mmHg or higher), or being on blood pressure medicine - low HDL cholesterol (less than 40 mg/dL) - family history of early heart disease (heart disease in father or brother before age 55; heart disease in mother or sister before age 65) - age (men 45 years or older; women 55 years or older). cigarette smoking high blood pressure (140/90 mmHg or higher), or being on blood pressure medicine low HDL cholesterol (less than 40 mg/dL) family history of early heart disease (heart disease in father or brother before age 55; heart disease in mother or sister before age 65) age (men 45 years or older; women 55 years or older).
- Don't smoke. - Keep blood glucose and blood pressure under control. - Keep blood fats close to normal. - Be physically active. - Ask your doctor if you should take aspirin every day. You also may need surgery to treat PAD.
Osteopetrosis is a bone disease that makes bones abnormally dense and prone to breakage (fracture). Researchers have described several major types of osteopetrosis, which are usually distinguished by their pattern of inheritance: autosomal dominant, autosomal recessive, or X-linked. The different types of the disorder can also be distinguished by the severity of their signs and symptoms. Mutations in at least nine genes cause the various types of osteopetrosis.
The NINDS supports and conducts a wide range of studies which focus on identifying and learning more about the genes involved in normal brain development. The knowledge gained from these fundamental studies provides the foundation for understanding how this process can go awry and, thus, may eventually give clues to understanding disorders such as Sotos syndrome.

Sarcoidosis affects people of all ages and races. However, it's more common among African Americans and Northern Europeans. In the United States, the disease affects African Americans somewhat more often and more severely than Whites. Studies have shown that sarcoidosis tends to vary amongst ethnic groups. For example, eye problems related to the disease are more common in Japanese people. Lofgren's syndrome, a type of sarcoidosis, is more common in people of European descent. Lofgren's syndrome may involve fever, enlarged lymph nodes, arthritis (usually in the ankles), and/or erythema nodosum. Erythema nodosum is a rash of red or reddish-purple bumps on your ankles and shins. The rash may be warm and tender to the touch. Sarcoidosis is somewhat more common in women than in men. The disease usually develops between the ages of 20 and 50. People who have a family history of sarcoidosis also are at higher risk for the disease. Researchers have looked for a link between sarcoidosis and exposure to workplace and environmental factors. However, no clear link has been found.
Is genetic testing available for thalassemia? Yes, genetic testing is available for HBB, HBA1 and HBA2, the genes known to cause thalassemia. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutations in the family are known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. It has additional information on genetic testing for alpha thalassemia and beta thalassemia. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.
Mutations in at least three genes can cause NBCIE. These genes provide instructions for making proteins that are found in the outermost layer of the skin (the epidermis). The epidermis forms a protective barrier between the body and its surrounding environment. The skin abnormalities associated with NBCIE disrupt this protective barrier, making it more difficult for affected infants to control water loss, regulate body temperature, and fight infections. Mutations in the ALOX12B and ALOXE3 genes are responsible for the majority of cases of NBCIE. Mutations in one other gene associated with this condition are found in only a small percentage of cases. In some people with NBCIE, the cause of the disorder is unknown. Researchers are looking for additional genes that are associated with NBCIE.
Batten disease is a fatal, inherited disorder of the nervous system that begins in childhood. In some cases, the early signs are subtle, taking the form of personality and behavior changes, slow learning, clumsiness, or stumbling. Symptoms of Batten disease are linked to a buildup of substances called lipopigments in the body's tissues. Lipopigments are made up of fats and proteins. Because vision loss is often an early sign, Batten disease may be first suspected during an eye exam. Often, an eye specialist or other physician may refer the child to a neurologist. Diagnostic tests for Batten disease include blood or urine tests, skin or tissue sampling, an electroencephalogram (EEG), electrical studies of the eyes, and brain scans.
Dermatitis herpetiformis is caused by the deposit of immunoglobulin A (IgA) in the skin, which triggers further immunologic reactions resulting in lesion formation. DH is an external manifestation of an abnormal immune response to gluten, in which IgA antibodies form against the skin antigen epidermal transglutaminase. Family studies show that 5 percent of first-degree relatives of a person with DH will also have DH. An additional 5 percent of first-degree relatives of a person with DH will have celiac disease.4 Various other autoimmune diseases are associated with DH, the most common being hypothyroidism.
Mutations in the ABCA1 gene cause Tangier disease. This gene provides instructions for making a protein that releases cholesterol and phospholipids from cells. These substances are used to make HDL, which transports them to the liver. Mutations in the ABCA1 gene prevent the release of cholesterol and phospholipids from cells. As a result, these substances accumulate within cells, causing certain body tissues to enlarge and the tonsils to acquire a yellowish-orange color. A buildup of cholesterol can be toxic to cells, leading to impaired cell function or cell death. In addition, the inability to transport cholesterol and phospholipids out of cells results in very low HDL levels, which increases the risk of cardiovascular disease. These combined factors cause the signs and symptoms of Tangier disease.
Ovarian small cell carcinoma is a rare cancer that typically occurs in young women. It is an aggressive tumor that can metastasize to other parts of the body. Ovarian small cell carcinoma is associated with hypercalcemia and is usually treated with platinum or etoposide-based chemotherapy.
Once you have cirrhosis, nothing can make all the scar tissue go away. But treating the cause will keep cirrhosis from getting worse. For example, if cirrhosis is from heavy alcohol use, the treatment is to completely stop drinking alcohol. If cirrhosis is caused by hepatitis C, then the hepatitis C virus is treated with medicine. Your doctor will suggest treatment based on the cause of your cirrhosis and your symptoms. Being diagnosed early and carefully following a treatment plan can help many people with cirrhosis. In the late stages of cirrhosis, certain treatments may not be effective. In that case, your doctor will work with you to prevent or manage the problems that cirrhosis can cause. What if the cirrhosis treatment doesnt work? If too much scar tissue forms, your liver could fail. Then you will need a liver transplant. A liver transplant can return you to good health. For information about liver transplantation, see the booklet What I need to know about Liver Transplantation from the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK).
Your paranasal sinuses are small hollow spaces around the nose. They are lined with cells that make mucus, which keeps your nose from drying out. The nasal cavity is the passageway just behind your nose. Air passes through it on the way to your throat as you breathe. Cancer of the nasal cavity and paranasal sinuses is rare. You are at greater risk if you are - Male and over 40 years old - Exposed to certain workplace chemicals - Infected with HPV - A smoker There may be no symptoms at first, and later symptoms can be like those of infections. Doctors diagnose nasal cancer with imaging tests, lighted tube-like instruments that look inside the nose, and biopsies. Treatment options include surgery, radiation, and chemotherapy.

Hereditary hemorrhagic telangiectasia (HHT) is an inherited disorder of the blood vessels that can cause excessive bleeding. People with this condition can develop abnormal blood vessels called arteriovenous malformations (AVMs) in several areas of the body. If they are on the skin, they are called telangiectasias. The AVMs can also develop in other parts of the body, such as the brain, lungs, liver, or intestines. HHT is caused by mutations in the ACVRL1, ENG, and SMAD4 genes. It is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. There is no cure for HHT. Treatment is symptomatic and supportive, with a focus on controlling bleeding, either through surgery or medication.
Mutations in the DNAJC19 gene cause DCMA syndrome. The DNAJC19 gene provides instructions for making a protein found in structures called mitochondria, which are the energy-producing centers of cells. While the exact function of the DNAJC19 protein is unclear, it may regulate the transport of other proteins into and out of mitochondria. The DNAJC19 gene mutations that cause DCMA syndrome lead to the production of an abnormally shortened protein that likely has impaired function. Researchers speculate that a lack of functional DNAJC19 protein alters the transport of other proteins into and out of the mitochondria. When too many or too few proteins move in and out of the mitochondria, energy production and mitochondrial survival can be reduced. Tissues that have high energy demands, such as the heart and the brain, are especially susceptible to decreases in cellular energy production. It is likely that this loss of cellular energy damages these and other tissues, leading to heart problems, movement difficulties, and other features of DCMA syndrome.
Like all arenaviruses, Lujo virus has a rodent host as its reservoir. Humans can contract LUHF through contact with an infected rodent. Contact can be direct or through inhalation of aerosolized Lujo virus from the urine or feces of infected rodents. Person-to-person transmission of Lujo virus was observed in the small, nosocomial cluster of hemorrhagic disease which resulted in the discovery of the Lujo virus. Transmission of arenaviruses, and Lujo virus in particular, is most likely the result of direct contact with the body fluids of an infected person, in the absence of infection control precautions.
Phosphoglycerate kinase deficiency appears to be a rare disorder. About 30 families with affected members have been reported in the scientific literature.
Acquired pulmonary alveolar proteinosis (PAP) is a rare, acquired lung disorder characterized by the accumulation of grainy material consisting mostly of protein and fat (lipoproteinaceous material) in the air sacs of the lungs (alveoli). Most cases affect adults between the ages of 20-50. The symptoms can vary greatly; some individuals may not show symptoms, while others may experience progressive difficulty breathing and shortness of breath upon exertion. Other signs and symptoms may include a dry, chronic cough; fatigue; weight loss; chest pain; and a general feeling of ill health. In rare cases, the coughing up of blood, rounding and swelling of the tips of the fingers, and cyanosis may be present. Most cases occur for no known reason, but some cases may occur secondary to environmental exposures or underlying diseases; some researchers believe it may be an autoimmune disorder. The treatment varies from case to case depending upon the age of the affected individual and severity of the disease. Acquired PAP differs from congenital PAP, an extremely rare form of PAP that occurs in some newborns.
Adult neuronal ceroid lipofuscinosis is a rare condition that affects the nervous system. Signs and symptoms usually begin around age 30, but they can develop anytime between adolescence and late adulthood. There are two forms of adult neuronal ceroid lipofuscinosis that are differentiated by their underlying genetic cause, mode of inheritance and certain symptoms: Type A is characterized by a combination of seizures and uncontrollable muscle jerks (myoclonic epilepsy); dementia; difficulties with muscle coordination (ataxia); involuntary movements such as tremors or tics; and dysarthria. It is caused by changes (mutations) in the CLN6 or PPT1 gene and is inherited in an autosomal recessive manner. Type B shares many features with type A; however, affected people also experience behavioral abnormalities and do not develop myoclonic epilepsy or dysarthria. It can be caused by mutations in the DNAJC5 or CTSF gene and is inherited in an autosomal dominant manner. Treatment options for adult neuronal ceroid lipofuscinosis are limited to therapies that can help relieve some of the symptoms.
Is Wilson disease inherited? Wilson disease is inherited in an autosomal recessive manner. This means that to be affected, a person must have a mutation in both copies of the responsible gene in each cell. The parents of an affected person usually each carry one mutated copy of the gene and are referred to as carriers. Carriers typically do not show signs or symptoms of the condition. When two carriers of an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be a carrier like each of the parents, and a 25% chance to not have the condition and not be a carrier.

Complete LCAT deficiency is caused by mutations in the LCAT gene. This gene provides instructions for making an enzyme called lecithin-cholesterol acyltransferase (LCAT). The LCAT enzyme plays a role in removing cholesterol from the blood and tissues by helping it attach to molecules called lipoproteins, which carry it to the liver. Once in the liver, the cholesterol is redistributed to other tissues or removed from the body. The enzyme has two major functions, called alpha- and beta-LCAT activity. Alpha-LCAT activity helps attach cholesterol to a lipoprotein called high-density lipoprotein (HDL). Beta-LCAT activity helps attach cholesterol to other lipoproteins called very low-density lipoprotein (VLDL) and low-density lipoprotein (LDL). LCAT gene mutations that cause complete LCAT deficiency either prevent the production of LCAT or impair both alpha-LCAT and beta-LCAT activity, reducing the enzyme's ability to attach cholesterol to lipoproteins. Impairment of this mechanism for reducing cholesterol in the body leads to cholesterol deposits in the corneas, kidneys, and other tissues and organs. LCAT gene mutations that affect only alpha-LCAT activity cause a related disorder called fish-eye disease that affects only the corneas.
Having certain inherited disorders can increase the risk of an extracranial germ cell tumor. Anything that increases your risk of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your childs doctor if you think your child may be at risk. Possible risk factors for extracranial germ cell tumors include the following: - Having certain genetic syndromes: - Klinefelter syndrome may increase the risk of germ cell tumors in the mediastinum. - Swyer syndrome may increase the risk of germ cell tumors in the testicles or ovaries. - Turner syndrome may increase the risk of germ cell tumors in the ovaries. - Having an undescended testicle may increase the risk of developing a testicular germ cell tumor.
Aquagenic pruritus is a condition in which contact with water of any temperature causes intense itching without any visible skin changes. The symptoms may begin immediately after contact with water and can last for an hour or more. The cause of aquagenic pruritus is unknown; however, familial cases have been described. The symptoms of the condition are similar to those seen in patients with other conditions; therefore, a thorough evaluation should be performed to rule out other more serious conditions. Overall, treatment is a challenge. Antihistamines, UVB phototherapy, PUVA therapy and various medications have been tried with varying success.
How might Behcet's disease be treated? Although there is no cure for Behet's disease, people can usually control symptoms with proper medication, rest, exercise, and a healthy lifestyle. The goal of treatment is to reduce discomfort and prevent serious complications such as disability from arthritis or blindness. The type of medicine and the length of treatment depend on the person's symptoms and their severity. It is likely that a combination of treatments will be needed to relieve specific symptoms. Patients should tell each of their doctors about all of the medicines they are taking so that the doctors can coordinate treatment. Topical medicine is applied directly on the sores to relieve pain and discomfort. For example, doctors prescribe rinses, gels, or ointments. Creams are used to treat skin and genital sores. The medicine usually contains corticosteroids (which reduce inflammation), other anti-inflammatory drugs, or an anesthetic, which relieves pain. Doctors also prescribe medicines taken by mouth to reduce inflammation throughout the body, suppress the overactive immune system, and relieve symptoms. Doctors may prescribe one or more of the medicines listed below to treat the various symptoms of Behet's disease. Corticosteroids Immunosuppressive drugs (Azathioprine, Chlorambucil or Cyclophosphamide, Cyclosporine, Colchicine, or a combination of these treatments) Methotrexate
How might fumarase deficiency be treated? There is currently no effective treatment for fumarase deficiency. Nutritional intervention may be appropriate for children with feeding difficulties. Physical therapy and wheelchairs can also be useful for some individuals.
Multiminicore disease is thought to be a rare disorder, although its incidence is unknown.
The prognosis depends upon the severity of symptoms. Children with early-onset AGS have the highest risk of death. Children with the later-onset form may be left with weakness or stiffness in the peripheral muscles and arms, weak muscles in the trunk of the body, and poor head control. Almost all children with AGS have mild to severe intellectual and physical impairment.
Diabetes-related Hypoglycemia - When people with diabetes think their blood glucose level is low, they should check it and treat the problem right away. - To treat hypoglycemia, people should have a serving of a quick-fix food, wait 15 minutes, and check their blood glucose again. They should repeat the treatment until their blood glucose is 70 mg/dL or above. - People at risk for hypoglycemia should keep quick-fix foods in the car, at workanywhere they spend time. - People at risk for hypoglycemia should be careful when driving. They should check their blood glucose frequently and snack as needed to keep their level 70 mg/dL or above. Hypoglycemia Unrelated to Diabetes - In reactive hypoglycemia, symptoms occur within 4 hours of eating. People with reactive hypoglycemia are usually advised to follow a healthy eating plan recommended by a registered dietitian. - Fasting hypoglycemia can be caused by certain medications, critical illnesses, hereditary enzyme or hormonal deficiencies, and some kinds of tumors. Treatment targets the underlying problem.
How might lamellar ichthyosis be treated? Unfortunately, there is currently no cure for lamellar ichthyosis. Management is generally supportive and based on the signs and symptoms present in each person. For infants, providing a moist environment in an isolette (incubator) and preventing infection are most important. Petrolatum-based creams and ointments are used to keep the skin soft, supple, and hydrated. As affected children become older, treatments to promote peeling and thinning of the stratum corneum (the outermost layer of skin cells) are often recommended. This may include humidification with long baths, lubrication, and keratolytic agents such as alpha-hydroxy acid or urea preparations. For people with ectropion (turning out of the eyelid), lubrication of the cornea with artificial tears or prescription ointments is helpful to prevent the cornea from drying out. Topical or oral retinoid therapy may be recommended for those with severe skin involvement; however, these medications can be associated with undesired side effects and are, therefore, generally prescribed with caution.
Adiposis dolorosa is a condition characterized by painful folds of fatty (adipose) tissue or the growth of multiple noncancerous (benign) fatty tumors called lipomas. This condition occurs most often in women who are overweight or obese, and signs and symptoms typically appear between ages 35 and 50. In people with adiposis dolorosa, abnormal fatty tissue or lipomas can occur anywhere on the body but are most often found on the torso, buttocks, and upper parts of the arms and legs. Lipomas usually feel like firm bumps (nodules) under the skin. The growths cause burning or aching that can be severe. In some people, the pain comes and goes, while in others it is continuous. Movement or pressure on adipose tissue or lipomas can make the pain worse. Other signs and symptoms that have been reported to occur with adiposis dolorosa include general weakness and tiredness (fatigue), depression, irritability, confusion, recurrent seizures (epilepsy), and a progressive decline in intellectual function (dementia). These problems do not occur in everyone with adiposis dolorosa, and it is unclear whether they are directly related to the condition.
Is hemifacial microsomia inherited? Hemifacial microsomia most often occurs in a single individual in a family and is not inherited. If the condition is caused by a chromosomal abnormality, it may be inherited from one affected parent or it may result from a new abnormality in the chromosome and occur in people with no history of the disorder in their family. In a very small number of cases, hemifacial microsomia is inherited in an autosomal dominant pattern, which means one copy of an altered gene in each cell is sufficient to cause the disorder. In rare cases, the condition is inherited in an autosomal recessive pattern, which means both copies of a gene in each cell have mutations. The parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but they typically do not show signs and symptoms of the condition. The gene or genes involved in hemifacial microsomia are unknown. In some affected families, people seem to inherit an increased risk of developing hemifacial microsomia, not the condition itself. In these cases, some combination of genetic changes and environmental factors may be involved.
