Is Hemifacial microsomia inherited ? | 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. | |
What are the treatments for Hemifacial microsomia ? | How might hemifacial microsomia be treated? Treatment of hemifacial microsomia varies depending on the features present and the severity in each affected person. Various types of surgeries may be needed in many cases. Some children need breathing support or a tracheostomy soon after birth if the jaw is severely affected. However in most cases, airway problems can be managed without surgery. Those with a jaw deformity and/or clefts may have feeding problems and may need supplemental feedings through a nasogastric tube to support growth and weight gain. Babies born with cleft lip or palate can have surgical repairs done during the first year. Cleft lip repair is typically performed when the child is 3-6 months old, while cleft palate surgery is generally performed when the child is about a year old. A lateral facial cleft, one of the most severe abnormalities associated with the condition, also requires reconstruction in stages. If eye closure is incomplete due to eyelid abnormalities or facial paralysis is present, a child may need eye protection or surgery. Surgery may also be used for eyelid differences to reposition the lower lids and corners of the eyes. Some children with abnormally shaped or missing ears may choose to have a series of reconstructive surgeries to make the ear appear more normal. Children with skin, cheek and other soft tissue deficiencies may need augmentation procedures such as fat grafting or tissue transfer. Severe bone abnormalities may require surgery as well. Because multiple body systems may be involved in hemifacial microsomia, affected people should continually be monitored for complications. | |
What is (are) Pityriasis rubra pilaris ? | Pityriasis rubra pilaris (PRP) refers to a group of skin conditions that cause constant inflammation and scaling of the skin. Affected people have reddish-orange colored patches; they may occur everywhere on the body or only on certain areas. There are several types of PRP, which are classified based on age of onset, body areas affected, and whether other associated conditions are present. PRP is usually sporadic (occurring randomly) but some forms may be inherited. | |
What are the symptoms of Pityriasis rubra pilaris ? | What are the signs and symptoms of Pityriasis rubra pilaris? Features of this condition vary greatly between affected individuals. The onset is gradual in the familial type and can be more rapid in the acquired type. Redness and scaling of the face and scalp are often seen first, followed by redness and thickening of the palms and soles. Overall, the elbows, knees, backs of the hands and feet, and ankles are most commonly affected. A more widespread eruption consisting of scaling orange-red plaques can be observed on the trunk and extremities. The lesions may expand and coalesce and eventually cover the entire body. When the disease becomes widespread, the nails, mucous membranes and eyes may be affected. The familial type often persists throughout life, but the acquired form may have periods of remission (periods of time where symptoms improve or completely resolve). The Human Phenotype Ontology provides the following list of signs and symptoms for Pityriasis rubra pilaris. 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) Irregular hyperpigmentation 90% Palmoplantar keratoderma 90% Abnormality of the fingernails 50% Pruritus 50% Abnormality of the oral cavity 7.5% Eczema 7.5% Ichthyosis 7.5% Lichenification 7.5% Neoplasm 7.5% Pustule 7.5% Autosomal dominant inheritance - Subungual hyperkeratosis - 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. | |
What causes Pityriasis rubra pilaris ? | What causes pityriasis rubra pilaris? In most cases, pityriasis rubra pilaris (PRP) occurs sporadically for unknown reasons. In a few families with the inherited form, familial PRP, the condition is caused by mutations in the CARD14 gene. This gene gives instructions for making a protein that turns on other proteins that regulate genes that control the body's immune responses and inflammatory reactions. It also protects cells from certain signals that would otherwise cause them to self-destruct. The CARD14 protein is particularly abundant in the skin. Mutations in the gene can cause a person to have an abnormal inflammatory response. Researchers are trying to find out how these mutations cause the specific features of familial PRP. | |
What are the treatments for Pityriasis rubra pilaris ? | How might pityriasis rubra pilaris be treated? Treatment of pityriasis rubra pilaris (PRP) is mainly based on reports of patients' experiences. No controlled trials have been done, so the effectiveness and safety of treatments is unclear. Currently there are no treatments approved by the US Food and Drug Administration (FDA) or the European Medicines Agency (EMA) for use in PRP. Management of PRP often involves systemic and topical therapies combined. Topical therapies can help with the symptoms and may be enough for people with mild PRP. Topical treatments are usually combined with systemic therapy for PRP that affects a large part of the body. Most people need systemic therapy to control the condition. Oral retinoids (synthetic vitamin A derivatives) are usually preferred as a first-line systemic treatment for PRP. Methotrexate may be an alternative option for people who should not use systemic retinoids, or who don't respond to systemic retinoid therapy. For people who don't respond well to retinoid or methotrexate therapy, options may include biologic TNF-alpha inhibitors, azathioprine, cyclosporine, and/or phototherapy. Topical treatments used for PRP may include topical corticosteroids, keratolytics, tar, calcipotriol, topical tretinoin, and tazarotene. Some of the medications used to treat PRP can harm a developing fetus and are not recommended for use right before or during pregnancy. People seeking information about specific treatment options for themselves or family members should speak with their health care provider. | |
What is (are) Keutel syndrome ? | Keutel syndrome is an inherited condition characterized by cartilage calcification in the ears, nose, larnyx, trachea (voice box), and ribs; pulmonary artery stenoses; brachytelephalangism (short fingers and nails that resemble drumsticks); and facial dysmorphism.

What is (are) Carnitine palmitoyltransferase 2 deficiency ? | Carnitine palmitoyltransferase 2 (CPT2) deficiency is a condition that prevents the body from using certain fats for energy, particularly during periods without food (fasting). There are three main types of CPT2 deficiency: a lethal neonatal form, a severe infantile hepatocardiomuscular form, and a myopathic form. The neonatal and infantile forms are severe multisystemic diseases characterized by liver failure with hypoketotic hypoglycemia (extremely low levels of ketones (substances produced when fat cells break down in the blood) and low blood sugar), cardiomyopathy, seizures, and early death. The myopathic form is characterized by exercise-induced muscle pain and weakness and occasional myoglobinuria (rust-colored urine indicating breakdown of muscle tissue). Mutations in the CPT2 gene cause CPT2 deficiency. It is inherited in an autosomal recessive pattern. Treatment is based on avoidance of prolonged fasting and a low-fat and high-carbohydrate diet. | |

What is (are) Abetalipoproteinemia ? | Abetalipoproteinemia is a condition characterized by the inability to fully absorb dietary fats, cholesterol and fat-soluble vitamins. Signs and symptoms appear in the first few months of life and can include failure to thrive; diarrhea; acanthocytosis; and stool abnormalities. Other features develop later in childhood and often impair the function of the nervous system, potentially causing slower intellectual development; poor muscle coordination; progressive ataxia; and an eye disorder called retinitis pigmentosa. Most of the symptoms are due to defects in the absorption and transport of vitamin E. Abetalipoproteinemia is caused by mutations in the MTTP gene and is inherited in an autosomal recessive manner. Early diagnosis, high-dose vitamin E therapy, and medium-chain fatty acid supplements may slow the progression of the nervous system abnormalities. Long-term outlook is reasonably good for most affected people who are diagnosed early. If left untreated, the condition can result in early death. | |

What causes Abetalipoproteinemia ? | What causes abetalipoproteinemia? Abetalipoproteinemia is caused by changes (mutations) in the MTTP gene. The MTTP gene gives the body instructions to make a protein needed for creating beta-lipoproteins. These lipoproteins are necessary for the body to absorb fats, cholesterol, and fat-soluble vitamins (vitamins A, D, E and K), and for transporting these substances in the blood. Mutations in the MTTP result in a lack of beta-lipoproteins, leading to an inability to absorb and transport these substances. This in turn leads to the nutritional and neurologic problems in affected people. | |
Is Abetalipoproteinemia inherited ? | How is abetalipoproteinemia inherited? Abetalipoproteinemia 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. Affected people inherit one mutated copy of the gene from each parent, who is referred to as a carrier. Carriers of an autosomal recessive condition typically do not have any signs or symptoms (they are unaffected). When 2 carriers of an autosomal recessive condition have children, each child has a: 25% (1 in 4) chance to be affected 50% (1 in 2) chance to be an unaffected carrier like each parent 25% chance to be unaffected and not be a carrier | |
How to diagnose Abetalipoproteinemia ? | Is genetic testing available for abetalipoproteinemia? Yes. The Genetic Testing Registry (GTR) provides information about the genetic tests available for abetalipoproteinemia. 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. Prenatal testing may also be available for pregnancies at increased risk if the mutations in the family have been identified. | |
What are the treatments for Abetalipoproteinemia ? | How might abetalipoproteinemia be treated? A nutritionist or other qualified medical professional should be consulted for specific dietary instruction in people with abetalipoproteinemia. Treatment involves very large doses of vitamin E, as well as large doses of vitamin supplements containing other fat-soluble vitamins (vitamin A, vitamin D, and vitamin K). Linoleic acid supplements are also recommended. Several diet changes and/or restrictions are also needed to prevent stomach problems. A low-fat diet may help with digestive symptoms; medium chain triglycerides may be used (under supervision of a specialist) as a source of fat in the diet. Management in adults typically focuses on specific complications associated with the disorder, and depends on the signs and symptoms present. Affected people may need consultations with several other types of specialists, including a lipidologist, gastroenterologist, hepatologist, ophthalmologist, and neurologist. | |
What is (are) Ovarian sex cord tumor with annular tubules ? | An ovarian sex cord tumor with annular tubules (SCTAT) is a tumor that grows from cells in the ovaries known as sex cord cells. As these cells grow, they form tube-like shapes in the tumor. SCTATs can develop in one or both ovaries, and may cause symptoms such as puberty at an exceptionally young age (precocious puberty), irregular menstrual cycles, or post-menopausal bleeding. Most ovarian SCTATs are benign. However, because there is a chance that an SCTAT may be malignant, treatment may include surgery to remove the tumor. | |
What causes Ovarian sex cord tumor with annular tubules ? | What causes an ovarian sex cord tumor with annular tubules? Approximately one third of ovarian sex cord tumors with annual tubules (SCTATs) develop because of an underlying genetic condition called Peutz Jeghers syndrome (PJS), which is caused by a mutation in the STK11 gene. In these genetic cases, many small SCTATs develop in both ovaries and are almost always benign. The remaining two thirds of ovarian SCTATs are not related to a genetic condition and develop as a single tumor in one ovary; up to 25% of SCTATs in this group may be malignant.

What is (are) Congenital central hypoventilation syndrome ? | Congenital central hypoventilation syndrome (CCHS) is a disorder of the autonomic nervous system that affects breathing. It causes a person to hypoventilate (especially during sleep), resulting in a shortage of oxygen and a buildup of carbon dioxide in the blood. Symptoms usually begin shortly after birth. Affected infants hypoventilate upon falling asleep and exhibit a bluish appearance of the skin or lips (cyanosis). Other features may include difficulty regulating heart rate and blood pressure; decreased perception of pain; low body temperature; sporadic profuse sweating; Hirschsprung disease; constipation; learning difficulties; eye abnormalities; and a characteristic facial appearance (having a short, wide, somewhat flattened face). CCHS is caused by a mutation in the PHOX2B gene and is inherited in an autosomal dominant manner. However, over 90% of cases are due to a new mutation in the affected person and are not inherited from a parent. Treatment typically includes mechanical ventilation or use of a diaphragm pacemaker. | |

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. | |
Is Congenital central hypoventilation syndrome inherited ? | How is congenital central hypoventilation syndrome inherited? Congenital central hypoventilation syndrome (CCHS) is inherited in an autosomal dominant manner. This means that having a change (mutation) in only one copy of the responsible gene in each cell is enough to cause features of the condition. The genetics of CCHS can be complex. Most people with CCHS have a new (de novo) mutation in the responsible gene (the PHOX2B gene). De novo mutations occur for the first time in the affected person and are not inherited from a parent. Some people with CCHS have a parent with the condition, and inherit the mutation from that parent. In some cases, an asymptomatic parent of a person with symptoms has a PHOX2B mutation in some of their germ cells (egg or sperm cells, not body cells). This is called germline mosaicism. Some of these parents also have a PHOX2B mutation in some of their body cells. This is called somatic mosaicism. Germline mosaicism with or without somatic mosaicism is present in about 25% of asymptomatic parents of people with CCHS. Parents with mosaicism should have a comprehensive assessment to determine if any features of CCHS are present. It is also recommended that parents of a person with a presumed de novo mutation have genetic testing for the presence of the mutation, including testing that detects mosaicism at low levels. | |
What is (are) Lattice corneal dystrophy type 1 ? | Lattice corneal dystrophy is a type of stromal dystrophy. It is characterized by the build up of protein fibers (i.e., amyloid) in the stroma. Symptoms may include corneal erosions, decreased vision, photosensitivity, and eye pain. Most cases of lattice dystrophy are caused by mutations in the TGFBI gene. | |

What is (are) Amniotic band syndrome ? | Amniotic band syndrome refers to a condition in which bands extend from (and originating from) the inner lining of the amnion. The amnion is the sac that surrounds the baby in the womb. As the baby develops in the womb, its extremities may become entangled in the amniotic band resulting in constriction or even amputation. When this happens the baby is said to have amniotic band syndrome. Amniotic bands are thought to happen sporadically or in association with trauma to the abdomen. It can be a complication after an amniocentesis and/or it can indicate early rupture of the amniotic sac. | |
What are the symptoms of Amniotic band syndrome ? | What are the signs and symptoms of Amniotic band syndrome? The symptoms of amniotic band syndrome depend on the severity and location of the constrictions. The mildest constrictions affect only the superficial skin and may not require treatment. Deeper constrictions may block lymphatic vessels, impair blood flow, and require immediate surgical care. When the bands affect the limbs, the lower part of the limbs are most often involved, especially the middle, long, and index fingers of the hand. When the feet are involved, the bands most commonly affect the big toe. Pressure from the bands may result in additional abnormalities, such as underdevelopment of a limb, bone abnormalities, amputations, leg-length discrepancy, and club feet. Constriction bands across the head and face may lead to facial clefts. Severe clefts affecting vital organs are often life-threatening. The Human Phenotype Ontology provides the following list of signs and symptoms for Amniotic band syndrome.

What causes Amniotic band syndrome ? | What causes amniotic bands? Amniotic bands are caused by damage to a part of the placenta called the amnion. Damage to the amnion may produce fiber-like bands that can trap parts of the developing baby. | |
How to diagnose Amniotic band syndrome ? | How is amniotic band syndrome diagnosed? The earliest reported detection of an amniotic band is at 12 weeks gestation, by vaginal ultrasound. On ultrasound the bands appear as thin, mobile lines, which may be seen attached to or around the baby. However these bands may be difficult to detect by ultrasound, and are more often diagnosed by the results of the fusion, such as missing or deformed limbs. | |
What are the treatments for Amniotic band syndrome ? | How might amniotic band syndrome be treated? Mild cases may not require treatment, however all bands need monitoring as growth occurs to watch for progressive constriction and swelling. Other constrictions may require surgical management; surgical options will vary depending on the abnormality. People with amniotic band syndrome who have amputations may benefit from the use of prosthetics. | |
What is (are) Bilateral generalized polymicrogyria ? | Bilateral generalized polymicrogyria is a rare neurological disorder that affects the cerebral cortex (the outer surface of the brain). This is the most widespread form of polymicrogyria and typically affects the entire surface of the brain. Signs and symptoms include severe intellectual disability, problems with movement, and seizures that are difficult or impossible to treat. While the exact cause of bilateral generalized polymicrogyria is not fully understood, it is thought to be due to improper brain development during embryonic growth. Most cases appear to follow an autosomal recessive pattern of inheritance. Treatment is based on the signs and symptoms present in each person. | |

What is (are) Congenital disorders of glycosylation ? | Congenital disorders of glycosylation (CDG) are a group of inherited metabolic disorders that affect a process called glycosylation. Glycosylation is the complex process by which all human cells build long sugar chains that are attached to proteins, which are called glycoproteins. There are many steps involved in this process, and each step is triggered by a type of protein called an enzyme. Individuals with a CDG are missing one of the enzymes that is required for glycosylation. The type of CDG that a person has depends on which enzyme is missing. Currently, there are 19 identified types of CDG. CDG type IA is the most common form. The symptoms of CDG vary widely among affected individuals. Some people have severe developmental delay, failure to thrive, and multiple organ problems, while others have diarrhea, low blood sugar (hypoglycemia), liver problems, and normal developmental potential. | |

What is (are) Chanarin-Dorfman syndrome ? | Chanarin-Dorfman syndrome is an inherited condition in which fats are stored abnormally in the body. Affected individuals cannot break down certain fats called triglycerides. These fats accumulate in organs and tissues, including skin, liver, muscles, intestine, eyes, and ears. At birth, affected individuals usually present with dry, scaly skin. Additional features include an enlarged liver,cataracts, difficulty with coordinating movements (ataxia), hearing loss, short stature, muscle weakness, nystagmus, and mild intellectual disability. The signs and symptoms vary greatly among individuals with this condition. Some people may have ichthyosis only, while others may have problems affecting many areas of the body. This condition is caused by mutations in the ABHD5 gene and is inherited in an autosomal recessive pattern. | |

What is (are) Alagille syndrome ? | Alagille syndrome is an inherited disorder in which a person has fewer than the normal number of small bile ducts inside the liver. It is a complex disorder that can affect other parts of the body including the heart, kidneys, blood vessels, eyes, face, and skeleton. Symptoms, including jaundice, pale, loose stools, and poor growth, typically develop in the first 2 years of life. Symptoms and symptom severity varies, even among people in the same family. Alagille syndrome is caused by mutations in the JAG1 and NOTCH2 genes. It is inherited in an autosomal dominant pattern. Treatment is symptomatic and supportive. In severe cases, liver transplant may be necessary. | |
What are the symptoms of Alagille syndrome ? | What are the signs and symptoms of Alagille syndrome? Alagille syndrome is a complex multisystem disorder involving the liver, heart, eyes, face, and skeleton. Symptoms typically present in infancy or early childhood. The severity of the disorder varies among affected individuals, even within the same family. Symptoms range from so mild as to go unnoticed to severe enough to require heart and/or liver transplants. One of the major features of Alagille syndrome is liver damage caused by abnormalities in the bile ducts. These ducts carry bile (which helps to digest fats) from the liver to the gallbladder and small intestine. In Alagille syndrome, the bile ducts may be narrow, malformed, and reduced in number. This results in a build-up of bile causing scarring that prevents the liver from working properly. This may lead to jaundice, itchy skin, and deposits of cholesterol in the skin (xanthomas). Alagille syndrome is also associated with several heart problems, including impaired blood flow from the heart into the lungs (pulmonic stenosis). Other heart-related problems include a hole between the two lower chambers of the heart (ventricular septal defect) and a combination of heart defects called tetralogy of Fallot. People with Alagille syndrome may also have distinctive facial features (including a broad, prominent forehead; deep-set eyes; and a small, pointed chin), problems with the blood vessels within the brain and spinal cord (central nervous system) and the kidneys, and an unusual butterfly shape of the bones of the spinal column (vertebrae). Detailed information about the symptoms associated with Allagille syndrome can be accessed through the National Digestive Diseases Information Clearinghouse (NDDIC) and GeneReviews.

What is (are) Behcet's disease ? | Behcet's disease is a chronic multisystem inflammatory disorder characterized by ulcers affecting the mouth and genitals, various skin lesions, and abnormalities affecting the eyes. In some people, the disease also results in arthritis (swollen, painful, stiff joints), skin problems, and inflammation of the digestive tract, brain, and spinal cord. Although it can happen at any age, symptoms generally begin when individuals are in their 20s or 30s. The disease is common in Japan, Turkey and Israel, and less common in the United States. The exact cause of Behcet's disease is still unknown. Treatment is symptomatic and supportive. Experience is evolving with the use of interferon-alpha and with agents which inhibit tumor necrosis factor (TNF) in the treatment of Behets disease. Behcet's disease is a lifelong disorder that comes and goes. Spontaneous remission over time is common for individuals with Behets disease but permanent remission of symptoms has not been reported. | |
What are the symptoms of Behcet's disease ? | What are the signs and symptoms of Behcet's disease? Symptoms of Behcet's disease include recurrent ulcers in the mouth (resembling canker sores) and on the genitals, and eye inflammation (uveitis). The disorder may also cause various types of skin lesions, arthritis, bowel inflammation, meningitis (inflammation of the membranes of the brain and spinal cord), and cranial nerve palsies. Behcet's is a multi-system disease; it may involve all organs and affect the central nervous system, causing memory loss and impaired speech, balance, and movement. The effects of the disease may include blindness, stroke, swelling of the spinal cord, and intestinal complications.

What causes Behcet's disease ? | What causes Behcet's disease? The exact cause of Behet's disease is unknown. Most symptoms of the disease are caused by inflammation of the blood vessels. Inflammation is a characteristic reaction of the body to injury or disease and is marked by four signs: swelling, redness, heat, and pain. Doctors think that an autoimmune reaction may cause the blood vessels to become inflamed, but they do not know what triggers this reaction. Under normal conditions, the immune system protects the body from diseases and infections by killing harmful "foreign" substances, such as germs, that enter the body. In an autoimmune reaction, the immune system mistakenly attacks and harms the body's own tissues. Behet's disease is not contagious; it is not spread from one person to another. Researchers think that two factors are important for a person to get Behet's disease. First, it is believed that abnormalities of the immune system make some people susceptible to the disease. Scientists think that this susceptibility may be inherited; that is, it may be due to one or more specific genes. Second, something in the environment, possibly a bacterium or virus, might trigger or activate the disease in susceptible people. | |
What are the treatments for Behcet's disease ? | 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 | |
What is (are) Spondylocostal dysostosis 3 ? | Spondylocostal dysostosis is a group of conditions characterized by abnormal development of the bones in the spine and ribs. In the spine, the vertebrae are misshapen and fused. Many people with this condition have an abnormal side-to-side curvature of the spine (scoliosis). The ribs may be fused together or missing. These bone malformations lead to short, rigid necks and short midsections. Infants with spondylocostal dysostosis have small, narrow chests that cannot fully expand. This can lead to life-threatening breathing problems. Males with this condition are at an increased risk for inguinal hernia, where the diaphragm is pushed down, causing the abdomen to bulge out. There are several types of spondylocostal dysostosis. These types have similar features and are distinguished by their genetic cause and how they are inherited. Spondylocostal dysostosis 3 is caused by mutations in the LFNG gene. It is inherited in an autosomal recessive manner. Treatment is symptomatic and supportive and may include respiratory support and surgery to correct inguinal hernia and scoliosis. | |
What are the symptoms of Spondylocostal dysostosis 3 ? | What are the signs and symptoms of Spondylocostal dysostosis 3? The Human Phenotype Ontology provides the following list of signs and symptoms for Spondylocostal dysostosis 3.

In these cases, the sign or symptom may be rare or common. | |
What is (are) Patulous Eustachian Tube ? | Patulous eustachian tube is a benign condition in which the eustachian tube stays open most of the time. The eustachian tube is the tube that runs between the middle ear and throat and regulates the ear pressure around the ear drum. Under normal circumstances, it remains closed most of the time, opening only on occasion to equalize air pressure between the middle ear and the exterior environment. Major symptoms include distorted autophony (hearing one's own voice or breathing), echoing which may interfere with speech production, wave-like sounds, and a sensation of fullness in the ear. In severe cases, vertigo and hearing loss may occur. Over time, individuals with patulous eustachian tube may develop serious and even extreme responses to the abnormal sounds and other findings. In most cases, the cause of patulous eustachian tube is unknown. Weight loss and pregnancy may be predisposing factors. Neurologic disorders that cause muscle atrophy such as stroke, multiple sclerosis, and motor neuron disease have been implicated in some cases of patulous eustachian tube. Other cases may be associated with medications such as oral contraceptives or diuretics. Other predisposing factors include fatigue, stress, anxiety, exercise, and temporomandibular joint syndrome. | |
What are the treatments for Patulous Eustachian Tube ? | How might patulous eustacian tube be treated? While no standard treatment has been found to work for every patient, there are several options that have been used to successfully manage the symptoms in a number of cases. Patients are often advised to recline or lower the head between the knees when symptoms occur. They may also be advised to avoid diuretics and/or increase weight. Medications which have been shown to work in some patients include nasal sprays containing anticholinergics, estrogen, diluted hydrochloric acid, chlorobutanol, or benzyl alcohol. Surgical treatment may be indicated in some cases. Information detailing treatment options can be accessed through Medscape Reference. | |

What is (are) Retinochoroidal coloboma ? | Retinochoroidal coloboma is an eye abnormality that occurs before birth. It is characterized by missing pieces of tissue in both the retina (the light-sensitive tissue lining the back of the eye) and choroid (the blood vessel layer under the retina). In many cases, retinochoroidal coloboma does not cause symptoms. However, complications such as retinal detachment may occur at any age. Other possible complications include loss of visual clarity or distorted vision; cataract; and abnormal blood vessel growth in the choroid (choroidal neovascularization). Retinochoroidal coloboma can involve one or both eyes, and may occur alone or in association with other birth defects. It can be inherited or can occur sporadically. | |
What is (are) Porokeratosis of Mibelli ? | Porokeratosis of Mibelli is a skin condition that usually develops in children or young adults. It begins as one or a few small, brownish bumps that grow into raised, bumpy patches. These patches slowly increase in size over time. The cause of this condition is unknown, though exposure to sunlight or other forms of radiation, genetic factors and a weakened immune system have been suggested as possible risk factors. Porokeratosis of Mibelli may sometimes harm normal tissue underlying the affected area; it may also develop into skin cancer. Treatment depends on the size, location, and aggressiveness of porokeratosis in each affected individual; it may include observation only, medication, or surgery. | |

What are the treatments for Porokeratosis of Mibelli ? | How might porokeratosis of Mibelli be treated? Treatment depends on the size, location, and aggressiveness of porokeratosis of Mibelli. Affected individuals are recommended to visit their personal physician regularly to watch for signs of skin cancer, limit sun exposure to the affected area, and use moisturizers as needed. Imiquimod cream has been found to be an effective treatment, as has 5-fluorouracil cream. A group of medications called retinoids (including acitretin and isotretinoin), as a pill or cream, may be another treatment option. If a skin cancer develops from porokeratosis of Mibelli, surgery is recommended. | |
What is (are) Encephalocele ? | Encephaloceles are rare neural tube defects characterized by sac-like protrusions of the brain and the membranes that cover it through openings in the skull. These defects are caused by failure of the neural tube to close completely during fetal development. The result is a groove down the midline of the upper part of the skull, or the area between the forehead and nose, or the back of the skull. When located in the back of the skull, encephaloceles are often associated with neurological problems. Encephaloceles are usually dramatic deformities diagnosed immediately after birth; but occasionally a small encephalocele in the nasal and forehead region can go undetected. There is a genetic component to the condition; it often occurs in families with a history of spina bifida and anencephaly in other family members. | |

What is (are) Rickets ? | Rickets is a condition that causes children to have soft, weak bones. It usually occurs when children do not get enough vitamin D, which helps growing bones absorb important nutrients. Vitamin D comes from sunlight and food. Skin produces vitamin D in response to the sun's rays. Some foods also contain vitamin D, including fortified dairy products and cereals, and some kinds of fish. | |
What are the symptoms of Rickets ? | What are the signs and symptoms of rickets? The signs and symptoms of rickets include: Bone pain or tenderness Bowed (curved) legs Large forehead Stunted growth Abnormally curved spine Large abdomen Abnormally shaped ribs and breastbone Wide wrist and elbow joints Teeth abnormalities | |
What causes Rickets ? | What causes rickets? Rickets is caused by a lack of vitamin D. A child might not get enough vitamin D if he or she: Has dark skin Spends too little time outside Has on sunscreen all the time when out of doors Doesn't eat foods containing vitamin D because of lactose intolerance or a strict vegetarian diet Is breastfed without receiving vitamin D supplements Can't make or use vitamin D because of a medical disorder such as celiac disease Has an inherited disorder that affects vitamin D levels | |
How to diagnose Rickets ? | How is rickets diagnosed? Rickets is typically diagnosed using specific blood tests and x-rays. Blood tests usually show low levels of calcium and phosphorus and high levels of alkaline phosphatase. Bone x-rays may show areas with calcium loss or changes in bone shape. Bone biopsies are rarely performed, but can confirm the diagnosis of rickets. | |
What are the treatments for Rickets ? | What treatment is available for rickets? The treatment for rickets depends on the cause of the condition. If rickets is caused by a lack of vitamin D in the diet, then it is usually treated with carefully adjusted levels of vitamin D and calcium. The child's condition may improve within a few weeks of treatment. If rickets is caused by an inherited disorder or another medical condition, a healthcare provider would determine the appropriate treatment. | |

What are the treatments for Limited cutaneous systemic sclerosis ? | How might CREST syndrome be treated? Unfortunately, CREST syndrome has no known cure. The condition carries both physical and psychological consequences, so a holistic approach to management should be taken. Treatment generally focuses on relieving signs and symptoms and preventing complications. Heartburn may be relieved by antacid medications that reduce the production of stomach acid. Medications that open small blood vessels and increase circulation may help relieve Raynaud's symptoms and reduce increased pressure in the arteries between the heart and lungs. Drugs that suppress the immune system have shown promise in preventing interstitial lung disease (a condition in which excess collagen collects in the tissue between the lungs' air sacs) in some people with CREST syndrome. To prevent loss of mobility, stretching exercises for the finger joints are important. A physical therapist can also show affected individuals some facial exercises that may help keep the face and mouth flexible. If CREST syndrome is making it difficult to perform daily tasks, an occupational therapist can help individuals learn new ways of doing things. For example, special toothbrushes and flossing devices can make it easier to care for the teeth. Surgery may be necessary for some affected individuals. Large or painful calcium deposits sometimes need to be surgically removed, and amputation of fingertips may be necessary if skin ulcers progress to gangrene. Depression affects approximately 45% of patients with systemic sclerosis and 64% also develop anxiety, so early assessment and treatment of these psychological issues is recommended. For pain management, studies have shown that oxycodone is effective and safe for pain due to severe skin ulcers, while topical lidocaine helps reduce pain of digital ulcers in individuals with systemic scleroderma. ` There are also some lifestyle changes and home remedies that may be helpful for some individuals with CREST syndrome. To reduce Raynaud's symptoms, individuals may consider wearing gloves or mittens outdoors when the weather is cool, and indoors when reaching into the freezer, for example. To maintain the body's core temperature, individuals may dress in layers and wear a hat or scarf, thermal socks, and well-fitting boots or shoes that don't cut off the circulation. Individuals who smoke should talk to their doctor about the best ways to quit. Nicotine constricts the blood vessels, making Raynaud's phenomenon worse. Individuals who have difficulty swallowing may consider choosing soft, moist foods and chewing food well. To minimize acid reflux individuals may eat small, frequent meals; avoid spicy or fatty foods, chocolate, caffeine, and alcohol; and avoid exercising immediately before or after eating. Sitting upright for a couple of hours after a meal may also help. To help keep skin soft, individuals may avoid harsh soaps and detergents, while choosing gentle skin cleansers and bath gels with added moisturizers. Individuals may also consider bathing less frequently and taking brief baths and showers, using warm rather than hot water. Moisture levels in the home may be improved by using a humidifier to ease skin and breathing symptoms. For additional information about how CREST syndrome may be treated, the following article from eMedicine may be helpful: http://emedicine.medscape.com/article/1064663-treatment#showall The information provided here is for general educational purposes only. Individuals interested in learning about specific treatment options for themselves or family members should speak with their healthcare provider. | |
What is (are) Cowden syndrome ? | Cowden syndrome is an inherited condition that is characterized primarily by multiple, noncancerous growths (called hamartomas) on various parts of the body. It is considered part of the PTEN Hamartoma Tumor Syndrome spectrum which also includes Bannayan-Riley-Ruvalcaba syndrome and Proteus syndrome. People affected by Cowden syndrome are also at an increased risk of developing certain types of cancer, such as breast, thyroid and endometrial (lining of the uterus) cancer. Most cases are caused by changes (mutations) in the PTEN gene and are inherited in an autosomal dominant manner. Management typically includes high-risk screening for associated tumors and/or prophylactic surgeries. | |
What are the symptoms of Cowden syndrome ? | What are the signs and symptoms of Cowden syndrome? Cowden syndrome is characterized primarily by multiple, noncancerous growths (called hamartomas) on various parts of the body. Approximately 99% of people affected by Cowden syndrome will have benign growths on the skin and/or in the mouth by the third decade of life. A majority of affected people will also develop growths (called hamartomatous polyps) along the inner lining of the gastrointestinal tract. People affected by Cowden syndrome also have an increased risk of developing certain types of cancer. Breast, thyroid and endometrial (the lining of the uterus) cancers are among the most commonly reported tumors. Other associated cancers include colorectal cancer, kidney cancer and melanoma. People with Cowden syndrome often develop cancers at earlier ages (before age 50) than people without a hereditary predisposition to cancer. Other signs and symptoms of Cowden syndrome may include benign diseases of the breast, thyroid, and endometrium; a rare, noncancerous brain tumor called Lhermitte-Duclos disease; an enlarged head (macrocephaly); autism spectrum disorder; intellectual disability; and vascular (the body's network of blood vessels) abnormalities. The Human Phenotype Ontology provides the following list of signs and symptoms for Cowden syndrome.

In these cases, the sign or symptom may be rare or common. | |
What causes Cowden syndrome ? | What causes Cowden syndrome? Most cases of Cowden syndrome are caused by changes (mutations) in the PTEN gene. PTEN is a tumor suppressor gene which means that it encodes a protein that helps keep cells from growing and dividing too rapidly or in an uncontrolled way. Mutations in PTEN result in a defective protein that is unable to carry out its normal role. This leads to the development of the various tumors and cancers associated with Cowden syndrome. Rarely, Cowden syndrome is caused by mutations in KLLN, SDHB, SDHC, SDHD, PIK3CA or AKT1. Some affected families have no identifiable mutation in any of the genes associated with Cowden syndrome; in these families, the exact underlying cause is unknown. | |
Is Cowden syndrome inherited ? | How is Cowden syndrome inherited? Cowden syndrome is inherited in an autosomal dominant manner. This means that to be affected, a person only needs a change (mutation) in one copy of the responsible gene in each cell. In some cases, an affected person inherits the mutation from an affected parent. Other cases may result from new (de novo) mutations in the gene. These cases occur in people with no history of the disorder in their family. A person with Cowden syndrome has a 50% chance with each pregnancy of passing along the altered gene to his or her child. | |
How to diagnose Cowden syndrome ? | How is Cowden syndrome diagnosed? A diagnosis of Cowden syndrome is based on the presence of characteristic signs and symptoms. Genetic testing for a change (mutation) in the PTEN gene can then be ordered to confirm the diagnosis. If a mutation in PTEN is not identified, genetic testing for the other genes known to cause Cowden syndrome can be considered. GeneReviews offers more detailed information regarding the diagnosis of Cowden syndrome including the clinical diagnostic criteria. Click here to view this resource. The PTEN Cleveland Clinic Risk Calculator can be used to estimate the chance of finding a PTEN mutation in children and adults with signs and symptoms of Cowden syndrome. Is genetic testing available for Cowden syndrome? Yes, genetic testing is available for many of the genes known to cause Cowden syndrome. Carrier testing for at-risk relatives and prenatal testing are possible if the disease-causing mutation in the family is known. The Genetic Testing Registry (GTR) is a centralized online resource for information about genetic tests. 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. | |
What are the treatments for Cowden syndrome ? | How might Cowden syndrome be treated? Because Cowden syndrome is associated with an increased risk for certain types of cancer, management is typically focused on high-risk cancer screening. According to the National Comprehensive Cancer Network 2014, the recommended screening protocol for Cowden syndrome includes: Cancer Screening for Women Breast self exams beginning at age 18 Clinical breast exams every 6-12 months beginning at age 25** Annual mammogram and breast MRI beginning at age 30-35** Annual screening for endometrial cancer with ultrasound and/or random biopsy may be considered beginning at age 30-35 Prophylactic surgeries may be considered as a preventative option for some forms of cancer Cancer Screening for Men and Women Annual physical examination beginning at age 18** Annual thyroid ultrasound beginning at age 18** Baseline colonoscopy at age 35 with follow-up every 5 years (more frequent if polyps identified) Consider renal (kidney) ultrasound every 1-2 years beginning at age 40 **or individualized based on the earliest diagnosis of cancer in the family GeneReviews offers more specific information on the treatment and management of Cowden syndrome.

What is (are) Hereditary multiple osteochondromas ? | Hereditary multiple osteochondromas (HMO) (formerly called hereditary multiple exostoses) is a genetic condition in which people develop multiple benign (noncancerous) bone tumors that are covered by cartilage (called osteochondromas). The number and location of osteochondromas varies greatly among affected individuals. These tumors are not present at birth, but almost all affected people develop multiple osteochondromas by the time they are 12 years old. Once the bones stop growing, the development of new osteochondromas also usually stops. Osteochondromas can cause abnormal growth of the arms, hands, and legs, which can lead to uneven limb lengths (limb length discrepancy) and short stature. These tumors may cause pain, limit joint movement, and exert pressure on nerves, blood vessels, and surrounding tissues. Osteochondromas are typically benign; however, researchers estimate that people with HMO have about a 1% lifetime risk of these tumors becoming a cancerous osteochondrosarcoma. HMO is caused by mutations in the EXT1 and EXT2 genes and is inherited in an autosomal dominant pattern. | |

Is Hereditary multiple osteochondromas inherited ? | How is hereditary multiple osteochondromas inherited? HMO is caused by mutations in the EXT1 and EXT2 genes. It is inherited in an autosomal dominant pattern, which means that one copy of the altered gene in each cell is sufficient to cause this condition. In most cases, an affected individual inherits the mutation from one affected parent. Other cases result from new mutations in the gene and occur in people with no history of the condition in their family. Most affected individuals (96%) that have inherited a gene mutation from their parent show signs and symptoms of this condition. However, the family history may appear negative because of the failure to recognize the disorder in family members and/or reduced penetrance. Reports have suggested that some females may not show clinical features of HMO but still have the gene mutation that causes this condition. | |

Surface irregularities and unorganized chalk deposits with light areas in the middle of the tumor and cartilage cap may be seen on a bone scan, ultrasound or preferably an MRI. However the diagnosis of chondrosarcoma can only be confirmed by a bone biopsy. What are the signs and symptoms of malignant transformation in hereditary multiple exostoses (HME)? A doctor may become suspicious of a malignant transformation if there is an increase in the size of the tumor in adults when bone growth is already complete. In addition, cancer should be suspected if the thickness of the cartilaginous cap of the osteochondroma is over 1-2 centimeters (normally, after bone growth is complete, the cap is only a few millimeters thick). Other signs of a malignant transformation may include bone pain, temporary loss of sensory or motor function due to compression of a nerve (neurapraxia) or pressure related symptoms in nearby organs. Is screening recommended for malignant transformation in hereditary multiple exostoses (HME)? At present, medical researchers agree that more studies need to be performed to determine the best screening protocols for those with HME, including the study of benefit/cost/risk. However a compelling study was published in 2014 by Czajka and DiCaprio which compares the screening of malignant transformation in people with HME to the screening of breast and cervical cancer in women. The authors conclude that screening should be offered to individuals with HME over the age of 16 (or when bone growth has been completed). They propose screening should include a thorough clinical examination and a full body MRI every two years. If an MRI is not possible than a bone scan be performed, followed by an ultrasound of the cartilage cap of any suspicious findings. The Czajka and DiCaprio further recommend that individuals with HME should be made aware of warning signs of malignant transformation and taught self examination techniques. | |
What are the treatments for Hereditary multiple osteochondromas ? | How might hereditary multiple osteochondromas (HMO) be treated? Currently, there is no known medical treatment for HMO. Osteochondromas are not usually removed because they stop growing around age 12. Another consideration is how close the tumor is to the affected bone's growth plate, because surgery can affect how the bone grows. Surgery may be considered, however, if an osteochondroma is causing pain, bone fracture, nerve irritation, or if the tumor continues to grow after the person's bones have stopped growing. The surgical treatment of choice is complete removal of the tumor. Depending on the location of the osteochondroma, this may be relatively simple. However, if an osteochondroma is close to nerves and blood vessels, this may make surgery difficult and risky. Surgery may also be necessary to correct painful limb abnormalities that are caused by multiple osteochondromas. Surgery may be needed to cut and realign the bones that have become deformed, which is known as osteotomy. If the legs are not equal in length, treatment may include a procedure to slow down the growth of the longer leg. Surgery may also be needed to correct the forearm deformity seen in this condition. Adults with this condition who have untreated forearm deformities usually do not have significant functional limitations. Although rare, an osteochondroma can become cancerous (malignant), which usually takes the form of a low grade chondrosarcoma. This type of malignant tumor is unlikely to spread elsewhere in the body. Higher grades of cancer can occur, but this is even more uncommon. In that case, other therapies, such as chemotherapy and radiation, may be used in treatment. GeneReviews provides more information about treatment for hereditary multiple osteochondromas. How might a malignant transformation in hereditary multiple exostoses (HME) be treated? Chondrosarcomas in a person with HME tend to be well differentiated and low grade tumors. The tumors usually grow slowly and do not readily metastasize. Surgical removal is the recommended treatment as the condrosarcomas do not respond to radiation or chemotherapy. The prognosis or long term outlook after surgical removal of the chondrosarcoma for a person with HME is good as long as the tumor has not metastasized. | |

What is (are) Salivary gland cancer, adult ? | Salivary gland cancer is a rare disease in which cancerous cells form in the tissues of the salivary glands. The salivary glands make saliva and release it into the mouth. Saliva has enzymes that help to digest food and antibodies that help protect against infections of the mouth and throat. There are 3 pairs of major salivary glands: the parotid glands, the sublingual glands, and the submandibular glands. The National Cancer Institute provides a picture of the anatomy of the salivary glands. Some risk factors for salivary gland cancer are older age, exposure to radiation of the head and/or neck area, and family history. Signs and symptoms of the disease may include: a lump near the ear, cheek, jaw, lip, or inside of the mouth; trouble swallowing; fluid draining from the ear; numbness or weakness in the face; and on-going pain in the face. Different types of treatment are available for patients with salivary gland cancer. Some treatments are standard (currently used by physicians) and some are being tested in clinical trials (by researchers). It is suggested that patients with salivary gland cancer have their treatment planned and managed by a team of doctors who are experts in treating head and neck cancer. Although treatment depends on the stage of the cancer, typically the following three treatments are used: (1) surgery, (2) radiation therapy, and (3) chemotherapy. [1] [2] | |

Less common forms are caused by a lack of other enzymes. These disorders can cause intellectual disability, seizures, problems with movement, and a blood disorder called megaloblastic anemia. Mutations in the CBS, MTHFR, MTR, and MTRR genes cause homocystinuria, and it is inherited in an autosomal recessive manner. Treatment varies depending upon the cause of the disorder. | |
What is (are) Actinomycosis ? | Actinomycosis is a chronic bacterial infection that commonly affects the face and neck. It is usually caused by an anaerobic bacteria called Actinomyces israelii. Actinomyces are normal inhabitants of the mouth, gastrointestinal tract, and female genital tract, and do not cause an infection unless there is a break in the skin or mucosa. The infection usually occurs in the face and neck, but can sometimes occur in the chest, abdomen, pelvis, or other areas of the body. The infection is not contagious. | |
What are the symptoms of Spinal muscular atrophy Ryukyuan type ? | What are the signs and symptoms of Spinal muscular atrophy Ryukyuan type? The Human Phenotype Ontology provides the following list of signs and symptoms for Spinal muscular atrophy Ryukyuan type. 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) Autosomal recessive inheritance - Fasciculations - Infantile onset - Kyphoscoliosis - Pes cavus - Proximal amyotrophy - Spinal muscular atrophy - 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. | |
