How to diagnose MTHFR gene mutation ? | Is genetic testing available to detect MTHFR gene mutations? Yes. Genetic testing is available for MTHFR gene mutations. This testing can be used in people with suspected homocystinuria or to determine the cause of elevated homocysteine levels in the blood. Genetic testing for C677T and A1286C may be indicated in a person with elevated homocysteine levels and one or more of the following, coronary artery disease venous thromboembolism stroke heart attack peripheral artery disease aneurysm high blood pressure recurrent pregnancy loss However, the American Heart Association recommends against testing for the common MTHFR gene mutations (C677T and A1298C) as a screen for increased risk of cardiovascular conditions. The College of American Pathologists and the American College of Medical Genetics recommend against testing for C677T and A1298C in people with blood clots. This is because the relationship between C677T and A1298C mutations and risk for cardiovascular disease is not completely understood. 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 MTHFR gene mutation ? | How might a MTHFR gene mutation be treated? High homocysteine levels in the body may occur if the MTHFR enzyme is not functioning normally due to MTHFR mutations, such as C677T and A1298C. Currently there are no treatments to remove adverse risks associated with MTHFR gene mutations. However, elevated levels of homocysteine can also occur if there is a lack of folate or B vitamins. Homocysteine levels also tend to rise with age, smoking, and use of certain drugs (such as carbamazepine, methotrexate, and phenytoin). It is important to ensure that people with and without MTHFR gene mutations receive adequate amounts of naturally occurring folate, choline, and B vitamins (B12, B6, and riboflavin) to mitigate nutritional risks. If adequate nutrition cannot be attained through diet alone, supplementation with folate (e.g., levomefolate (5-methyl THF) or folinic acid) and B vitamins is considered. We recommend that you talk to your doctor to learn if supplementation would benefit you. Smoking cessation and, when possible, avoidance of medications that adversely affect homocystiene level are additional management strategies. | |
What is (are) Split hand foot malformation ? | Split hand foot malformation (SHFM) is a type of birth defect that consists of missing digits (fingers and/or toes), a deep cleft down the center of the hand or foot, and fusion of remaining digits. The severity of this condition varies widely among affected individuals. SHFM is sometimes called ectrodactyly; however, this is a nonspecific term used to describe missing digits. SHFM may occur by itself (isolated) or it may be part of a syndrome with abnormalities in other parts of the body. At least six different forms of isolated SHFM have been described. Each type is associated with a different underlying genetic cause. SHFM1 has been linked to chromosome 7, and SHFM2 is linked to the X chromosome. SHFM3 is caused by a duplication of chromosome 10 at position 10q24. Changes (mutations) in the TP63 gene cause SHFM4. SHFM5 is linked to chromosome 2, and SHFM6 is caused by mutations in the WNT10B gene. SHFM may be inherited in an autosomal dominant, autosomal recessive, or X-linked manner. | |

What causes Split hand foot malformation ? | What causes split hand foot malformation? Split hand foot malformation may occur as an isolated feature or it may be associated with a genetic syndrome. Researchers believe that a large number of mutations can cause split hand foot malformation. A few of which have been identified: FBXW4 and TP63. Most commonly the conditions are passed through families in an autosomal dominant fashion with reduced penetrance. In autosomal dominant inheritance an affected parent would have a 1 in 2 or 50% chance with each pregnancy of passing the genetic defect to his/her offspring. In conditions with reduced penetrance a person who inherits the underlying genetic defect, may never develop the condition. More rarely other forms of inheritance have been reported (e.g., autosomal-recessive, X-linked, chromosome deletions, chromosome duplications). | |

What is (are) Konigsmark Knox Hussels syndrome ? | Konigsmark Knox Hussels syndrome is an inherited condition that causes both hearing and vision loss. This condition is characterized by late-onset progressive sensorineural deafness and progressive optic atrophy, which results in mildly reduced visual acuity. Some affected individuals can develop ophthalmoplegia (paralysis of the muscles that control eye movements), ptosis, ataxia, and non-specific myopathy in middle age. This condition is caused by a particular mutation in the OPA1 gene and is inerited in an autosomal dominant fashion. | |

What is (are) Congenital dyserythropoietic anemia type 2 ? | Congenital dyserythropoietic anemia type 2 (CDA II) is an inherited blood disorder characterized by mild to severe anemia. It is usually diagnosed in adolescence or early adulthood. Many affected individuals have yellowing of the skin and eyes (jaundice) and an enlarged liver and spleen (hepatosplenomegaly) and gallstones. This condition also causes the body to absorb too much iron, which builds up and can damage tissues and organs. In particular, iron overload can lead to an abnormal heart rhythm (arrhythmia), congestive heart failure, diabetes, and chronic liver disease (cirrhosis). Rarely, people with CDA type II have mediastinal tumors. CDA type II usually results from mutations in the SEC23B gene. It is inherited in an autosomal recessive pattern. Treatment depends on the severity of the symptoms and may involve blood transfusions, iron chelation therapy and removal of the spleen and gallbladder. | |

What are the treatments for Congenital dyserythropoietic anemia type 2 ? | How might congenital dyserythropoietic anemia (CDA) type 2 be treated? The goal of CDA type 2 treatment is to address and prevent complications from anemia and iron overload. Most people with CDA type 2 develop iron overload, for some this is as early as in their 20's. If a person with CDA type 2 has mild anemia, but evidence of iron loading, treatment may involve phlebotomy. An alternative treatment is chelation therapy. In particular, chelation therapy is preferred for people with iron (ferritin) levels greater than 1000 mg/L. The Iron Disorders Institute provides information on chelation therapy through their Web site at: http://www.irondisorders.org/chelation-therapy Many people with CDA-2 maintain hemoglobin levels just above the threshold for symptoms. Mild anemia may not need treatment, as long as it doesn't worsen. Less commonly CDA-2 causes severe anemia. Treatment of severe anemia may involve blood transfusions. Blood transfusions can raise iron levels so, careful monitoring and treatment for iron overload is required. The National Heart, Lung, and Blood Institute offers tips for living with hemolytic anemia at the following link: http://www.nhlbi.nih.gov/health/health-topics/topics/ha/livingwith Splenectomy is considered for people with CDA-2 and severe anemia. Splenectomy can cause a consistent rise in hemoglobin values. The spleen, however, is important in fighting infection. People, particularly children, who have had a splenectomy are more likely to contract a serious and possibly life-threatening infection (sepsis). This risk must be carefully weighed. Splenectomy does not affect iron overload. Lastly, people with very severe CDA-2 may be candidates for hematopoietic stem cell transplantation (HSCT). Currently this is the only available curative treatment for CDA-2. | |

What is (are) Leukoplakia ? | Leukoplakia is a condition in which thickened, white patches form on the tongue, gums, inside of the cheek, or sometimes on the outer female genitals. Although the sores can vary in appearance, they are usually white or gray; thick; and slightly raised with a hard surface. The condition is thought to be caused by irritation, but the cause is not always known. Tobacco is considered to be the main cause of its development in the mouth. Most patches are benign, but a small percentage show early signs of cancer. Removing the source of irritation may cause the condition to go away, but surgery to remove the sore(s) may be necessary in some cases. | |
What are the symptoms of Leukoplakia ? | What are the early signs of cancer in vulvar leukoplakia? Early signs of cancer may not be apparent. The clinical appearance of leukoplakia does not generally correlate with its appearance when examined under a microscope. For example, the lesion may appear unchanged for a period of time but may actually show changes when looked at under a microscope. Therefore, a biopsy is typically recommended in all cases to determine which lesions are precancerous. Small lesions may be biopsied and just followed periodically if it is shown to remain benign. However, those that show precancerous or cancerous features should be removed. | |
What are the treatments for Leukoplakia ? | How might leukoplakia be treated? For most people, removing the source of irritation is important and often causes the lesion to disappear. For example, if tobacco use is thought to be the cause, stopping tobacco use usually clears the condition. Dental causes such as rough teeth or fillings should be treated as soon as possible. When this is not effective or if the lesions show early signs of cancer, treatment may include removing the patches. The lesion is usually removed in the health care provider's office using local anesthesia. Leukoplakia on the vulva is treated in the same way as oral lesions. Recurrences are common, so follow-up visits with a physician are recommended. | |

What is (are) Neuroacanthocytosis ? | Neuroacanthocytosis (NA) refers to a group of genetic disorders that are characterized by misshapen, spiny red blood cells (acanthocytosis) and neurological abnormalities, especially movement disorders. The onset, severity and specific physical findings vary depending upon the specific type of NA present. Signs and symptoms usually include chorea (involuntary, dance-like movements), involuntary movements of the face and tongue, progressive cognitive impairment, muscle weakness, seizures and behavioral or personality changes. NA syndromes typically progress to cause serious, disabling complications and are usually fatal. NA is inherited, but the disease-causing gene and inheritance pattern varies for each type. Although there is some disagreement in the medical literature about what disorders should be classified as forms of NA, four distinct disorders are usually classified as the "core" NA syndromes - chorea-acanthocytosis, McLeod syndrome, Huntington's disease-like 2 and pantothenate kinase-associated neurodegeneration (PKAN). | |
What are the treatments for Neuroacanthocytosis ? | How might neuroacanthocytosis be treated? There is currently no cure for neuroacanthocytosis. Management generally focuses on the specific symptoms that are present in each individual and may require the coordination of various specialists. Psychiatric symptoms and chorea may be treated with certain antipsychotic medications known as dopamine-receptor blocking drugs. Other antipsychotic medications as well as antidepressants and/or sedatives may also be used to treat some affected individuals. Seizures may be treated with anti-convulsants, which may also help to treat psychiatric symptoms. Anti-seizure medications that can can worsen involuntary movements are generally avoided. Dystonia has been treated with botulinum toxin to relax the muscles and reduce spasms. Because of feeding difficulties in some cases, individuals may need to have their nutrition monitored. Nutritional support, supplementation and/or a feeding tube may be necessary in some cases. Additional therapies that may be used to treat affected individuals may include speech therapy, physical therapy and occupational therapy. Mechanical devices, such as braces or a wheelchair, may benefit some people. Computer-assisted speech devices may be necessary in some cases.

What is (are) Fournier gangrene ? | Fournier gangrene refers to the death of body tissue of the genitals and/or perineum. Signs and symptoms of the condition include genital pain, tenderness, redness, and swelling with a rapid progression to gangrene. Although the condition can affect men and women of all ages, it is most commonly diagnosed in adult males. Most cases of Fournier gangrene are caused by an infection in the genital area or urinary tract. People with impaired immunity (i.e. due to diabetes or HIV) have an increased susceptibility to the condition. Treatment generally includes surgery and medications such as antibiotics and/or antifungal therapy. | |

What is (are) Osteogenesis imperfecta ? | Osteogenesis imperfecta (OI) is a group of genetic disorders that mainly affect the bones. People with this condition have bones that break easily, often from little or no trauma. Severity varies among affected people. Multiple fractures are common, and in severe cases, can even occur before birth. Milder cases may involve only a few fractures over a person's lifetime. People with OI also have dental problems (dentinogenesis imperfecta) and hearing loss in adulthood. Other features may include muscle weakness, loose joints, and skeletal malformations. There are various recognized forms of OI which are distinguished by their features and genetic causes. Depending on the genetic cause, OI may be inherited in an autosomal dominant (more commonly) or autosomal recessive manner. Treatment is supportive and aims to decrease the number of fractures and disabilities. | |

What causes Osteogenesis imperfecta ? | What causes osteogenesis imperfecta? Osteogenesis imperfecta (OI) may be caused by changes (mutations) in any of several genes. OI is most commonly due to a mutation in either the COL1A1 or COL1A2 gene, causing OI types I through IV. These genes play a role in how the body makes collagen, a material that helps to strengthen the bones. The type and severity of OI depends on the effect that the specific mutation has on normal collagen production. OI caused by mutations in these genes is inherited in an autosomal dominant manner. In about 10% of people with OI, the COL1A1 and COL1A2 genes are normal and the condition is due to mutations in other genes; many of these people have an autosomal recessive form of OI. Other genes in which mutations may be responsible for less common types of OI, some of which have been reported in only one individual or family, include: IFITM5 (type V) SERPINF1 (type VI) CRTAP (type VII) LEPRE1, also called P3H1 (type VIII) PPIB (type IX) SERPINH1 (type X) FKBP10 (type XI) SP7 (type XII) BMP1 (type XIII) TMEM38B (type XIV) WNT1 (type XV) SPARC (type XVII) | |
Is Osteogenesis imperfecta inherited ? | How is osteogenesis imperfecta inherited? Osteogenesis imperfecta (OI) is most commonly inherited in an autosomal dominant manner. This means that having only one changed (mutated) copy of the responsible gene in each cell is enough to cause features of OI. The mutated copy of the gene may be inherited from an affected parent, or it may occur for the first time in an affected person (a de novo mutation). When a person with an autosomal dominant form of OI has children, each child has a 50% (1 in 2) chance of inheriting the mutated gene. If the child inherits the mutated gene, the child's symptoms may be milder, or more severe, than those of the parent. Less commonly, OI is inherited in an autosomal recessive manner. This means that both copies of the responsible gene in each cell must have a mutation for a person to be affected. The parents of a person with an autosomal recessive condition typically are unaffected, but each carry one mutated copy of the gene. When two carriers of an autosomal recessive form of OI have children, each child has a 25% (1 in 4) chance to be affected, a 50% (1 in 2) chance to be a carrier like each parent, and a 25% chance to be unaffected and not be a carrier. | |
How to diagnose Osteogenesis imperfecta ? | Is genetic testing available for osteogenesis imperfecta? Genetic testing is available for individuals with osteogenesis imperfecta. The rate for detecting mutations in the genes that are responsible for OI varies depending on the type. Carrier testing may be available to relatives of affected individuals if the type of OI, disease-causing gene, and specific mutation in the affected individual are known. Prenatal testing for at-risk pregnancies can be performed by analysis of collagen made by fetal cells obtained by chorionic villus sampling (CVS) at about ten to 12 weeks' gestation if an abnormality of collagen has been identified in cells from the affected individual. Analysis of collagen after an amniocentesis (usually performed at 15-20 weeks gestation) is not useful, because the cells obtained do not produce type I collagen. However, prenatal testing can be performed by analyzing the genes (molecular genetic testing) if the specific mutation has been identified in the affected relative. GeneTests lists the names of laboratories that are performing genetic testing for different types of osteogenesis imperfecta. To view the contact information for the clinical laboratories conducting testing, click here and click on "Testing" next to the type of OI in which you are interested. Please note that most of the laboratories listed through GeneTests do not accept direct contact from patients and their families; therefore, if you are interested in learning more, you will need to work with a health care provider or genetics professional. Genetics professionals, such as genetic counselors, can also explain the inheritance of OI in detail including information about genetic risks to specific family members. | |
What is (are) Muscle eye brain disease ? | Muscle eye brain disease is a rare form of congenital muscular dystrophy. Individuals with this condition are born with muscle weakness (hypotonia), severe nearsightedness (myopia), glaucoma, and brain abnormalities. They also have developmental delay and intellectual disability. People with muscle eye brain disease frequently have additional eye abnormalities, hydrocephalus, and distinctive facial features. This condition is caused by mutations in gene a called POMGNT1, and it is inherited in an autosomal recessive pattern. The signs and symptoms of this condition vary among affected individuals, even among members of the same family. | |

What causes Muscle eye brain disease ? | What causes muscle eye brain disease? Muscle eye brain disease is caused by mutations in the POMGNT1 gene. This gene provides instructions for making a protein that is involved in adding sugar molecules to a protein called alpha dystroglycan. Alpha dystroglycan is important for stabilizing the muscle cell during contraction and relaxation. This protein is also found in the brain and spinal cord (central nervous system), eye, and other parts of the body. All of the reported mutations in the POMGNT1 gene result in a complete loss of function of the POMGNT1 protein. The lack of functional POMGNT1 protein disrupts production of alpha dystroglycan. | |

What is (are) Gamma aminobutyric acid transaminase deficiency ? | GABA (gamma-aminobutyric acid) is an important molecule which slows down the activity of cells in the brain.[1] GABA is broken down in the body by a substance known as 4-aminobutyrate aminotransferase, also known as GABA-transaminase or GABA-T.[1] Mutations in the ABAT gene can cause less GABA-T to be made, a condition known as GABA-T deficiency.[1] The symptoms for an individual with GABA-T deficiency can include: psychomotor retardation (a slowing down of thought and activity), low muscle tone, hyperactive responses, lethargy, seizures, and EEG abnormalities.[1] GABA-T deficiency is very rare, with fewer than 5 cases reported in the literature.[2] It is thought to be inherited in an autosomal recessive manner.[3][4] | |
What is (are) Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia ? | Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare condition in which cells called neuroendocrine cells spread and cluster in the small airways of the lungs. The majority of affected individuals are middled-aged women. Symptoms include shortness of breath and coughing. It is considered to be a precursor for pulmonary carcinoid tumors. Because so few cases have been reported in the medical literature, there is limited information on the prognosis and management of this condition. | |
What is (are) 22q13.3 deletion syndrome ? | 22q13.3 deletion syndrome, also known as Phelan-McDermid syndrome, is a chromosome abnormality caused by the loss (deletion) of a small piece of chromosome 22. The deletion occurs near the end of the long arm (or q arm) at a location designated as q13.3. The signs and symptoms of this condition vary widely from person to person. Common symptoms include low muscle tone (hypotonia), intellectual disability, delayed or absent speech, abnormal growth, tendency to overheat, large hands, and abnormal toenails. Affected individuals may have characteristic behaviors, such as mouthing or chewing on non-food items, decreased perception of pain, and autistic-like behaviors. The loss of a particular gene on chromosome 22, called the SHANK3 gene, is likely responsible for many of the signs and symptoms of 22q13.3 deletion syndrome. Additional genes within the deleted region probably contribute to the variable features of the syndrome. | |

In these cases, the sign or symptom may be rare or common. | |
What is (are) Schindler disease type 1 ? | Schindler disease is an inherited condition that primarily causes neurological problems. There are three types of Schindler disease. Schindler disease type 1, also called the infantile type, is the most severe form. Babies with this condition appear healthy a birth, but by the age of 8 to 15 months they stop developing new skills and begin losing skills they had already acquired. As the condition progresses, affected individuals develop blindness and seizures, and eventually lose awareness of their surroundings and become unresponsive. People with this form of the condition usually don't survive past early childhood. Schindler disease type 1 is caused by mutations in the NAGA gene. The condition follows an autosomal recessive pattern of inheritance. | |

What causes Schindler disease type 1 ? | What causes Schindler disease type 1? Schindler disease type 1 is caused by mutations in the NAGA gene. This gene provides instructions for making the enzyme alpha-N-acetylgalactosaminidase.This enzyme works in the lysosomes (compartments within cells that digest and recycle materials) to help break down complexes called glycoproteins and glycolipids (sugar molecules attached to certain proteins and fats). More specifically, alpha-N-acetylgalactosaminidase helps remove a molecule called alpha-N-acetylgalactosamine from sugars in these complexes. Mutations in the NAGA gene interfere with the ability of the alpha-N-acetylgalactosaminidase enzyme to perform its role in breaking down glycoproteins and glycoliipids. These substances accumulate in the lysosomes and cause cells to malfunction and eventually die. Cell damage in the nervous system and other tissues and organs of the body leads to the signs and symptoms of Schindler disease type 1. | |
Is Schindler disease type 1 inherited ? | How is Schindler disease type 1 inherited? Schindler disease type 1 is inherited in an autosomal recessive pattern. This means that 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 so not show signs and symptoms of the condition. | |

What is (are) Epithelial basement membrane corneal dystrophy ? | Epithelial basement membrane corneal dystrophy is a condition where the epithelium of the cornea (the outermost region of the cornea) loses its normal clarity due to a buildup of cloudy material. It gets its name from the unusual appearance of the cornea during an eye exam. This dystrophy occurs when the epithelium's basement membrane develops abnormally, causing the epithelial cells to not properly adhere to it. This leads to recurrent epithelial erosions, which can cause blurred vision and severe pain. This condition is usually not inherited. However, families with autosomal dominant inheritance and mutations in the TGFBI gene have been identified. | |
What are the symptoms of Epithelial basement membrane corneal dystrophy ? | What are the signs and symptoms of Epithelial basement membrane corneal dystrophy? A chronic problem seen in this condition is the epithelial erosions. They can alter the cornea's normal curvature, causing periodic blurred vision. These erosions may also expose the nerve endings that line the tissue, resulting in moderate to severe pain lasting as long as several days. Generally, the pain will be worse upon awakening in the morning. Other symptoms include sensitivity to light, excessive tearing, and foreign body sensation in the eye. This condition usually affects adults between the ages of 40 and 70, although it can develop earlier in life. It gets its name from the unusual appearance of the cornea during an eye exam. Most often, the affected epithelium will have a map-like appearance, i.e., large, slightly gray outlines that look like a continent on a map. There may also be clusters of opaque dots close to the map-like patches. Less frequently, the irregular basement membrane will form concentric lines in the central cornea that resemble small fingerprints. Epithelial basement membrane corneal dystrophy is not a progressive condition. Typically, it will flare up occasionally for a few years and then go away on its own, with no lasting loss of vision. Most people never know that they have this condition, since they do not have any pain or vision loss. The Human Phenotype Ontology provides the following list of signs and symptoms for Epithelial basement membrane corneal dystrophy.

What are the treatments for Epithelial basement membrane corneal dystrophy ? | How might epithelial basement membrane corneal dystrophy be treated? Because most people do not develop noticeable signs or symptoms, treatment usually is not necessary. However, if treatment is needed, doctors will try to control the pain associated with the epithelial erosions. They may patch the eye to immobilize it, or prescribe lubricating eye drops and ointments. With treatment, these erosions usually heal within three days, although periodic flashes of pain may occur for several weeks thereafter. Other treatments include anterior corneal punctures to allow better adherence of cells; corneal scraping to remove eroded areas of the cornea and allow regeneration of healthy epithelial tissue; and use of the excimer laser to remove surface irregularities.

What is (are) Chronic active Epstein-Barr virus infection ? | Chronic active Epstein-Barr virus infection is a rare condition in which the body makes too many lymphocytes, a type of white blood cell. Lymphocytes are an important part of the immune system because they help fight off diseases and protect the body from infection. About 95% of adults are infected with Epstein-Barr virus (EBV). Most infections occur during childhood and do not cause any symptoms. EBV infection in adolescents or young adults can often result in infectious mononucleosis. Rarely, people infected with EBV develop a life-threatening condition called chronic active EBV virus (CAEBV). Patients with CAEBV most often have fever, liver dysfunction, an enlarged spleen (splenomegaly), swollen lymph nodes (lymphadenopathy), and low numbers of platelets (thrombocytopenia). Hematopoietic stem cell transplantation has shown promise in the treatment of CAEBV. | |

What is (are) Pars planitis ? | Pars planitis is a disease of the eye that is characterized by inflammation of the narrowed area (pars plana) between the colored part of the eye (iris) and the choroid. This may lead to blurred vision; dark, floating spots in the vision; and progressive vision loss. As the condition advances, cataracts, retinal detachment, or macular edema (fluid within the retina) may develop. Pars planitis most often affects young men and is generally not associated with any other disease or symptoms (idiopathic); however, it can be associated with other autoimmune conditions such as multiple sclerosis and sarcoidosis. Treatment typically includes corticosteroid drugs, immunosuppressive medications, and/or surgery. | |
What are the symptoms of Pars planitis ? | What are the signs and symptoms of pars planitis? Pars planitis is characterized by inflammation of the narrowed area (pars plana) between the colored part of the eye (iris) and the choroid. This may lead to blurred vision; dark, floating spots in the vision; and progressive vision loss. Approximately 80% of cases are bilateral (affecting both eyes), although one eye is typically more affected than the other. As the condition advances, cataracts, retinal detachment, or macular edema (fluid within the retina) may develop. | |
What causes Pars planitis ? | What causes pars planitis? The exact underlying cause of pars planitis is unknown. Scientists suspect that it is an autoimmune condition in which the body's immune system mistakenly attacks healthy tissues (certain parts of the eyes, in this case). This is further supported by the fact that pars planitis is sometimes associated with other autoimmune conditions such as multiple sclerosis and sarcoidosis. Although most cases occur sporadically in people with no family history of the condition, pars planitis can rarely affect more than one family member. In these cases, there may be a genetic component; however, a disease-causing gene and specific inheritance pattern have not been identified. | |
How to diagnose Pars planitis ? | How is pars planitis diagnosed? Pars planitis is typically diagnosed based on a specialized eye examination. During the exam, the ophthalmologist will typically see clusters of white blood cells trapped within the eyeball that are called snowballs (or "inflammatory exudate"). If these clusters are located on the pars plana, they are known as snowbanks. Snowbanks are considered a "hallmark" sign of pars planitis. It is often recommended that people over age 25 with pars planitis have an MRI of their brain and spine to rule out multiple sclerosis. | |
What are the treatments for Pars planitis ? | How might pars planitis be treated? The first approach to treating pars planitis is corticosteroid eye drops or injections near the eye to control inflammation. Non-steroidal anti-inflammatory drugs (NSAIDs, including aspirin) or steroid medications (such as prednisone) can be taken by mouth. If these strategies are not successful, other medications may be given to reduce the body's immune response (medications called immunosuppressants, such as methotrexate). If medications are not effective, surgery may be considered. Cryotherapy has been performed in affected people to remove eye tissue that has inflammation. Although this surgery has been shown to be effective in restoring clarity of vision, there are concerns that it may cause damage to other parts of the eye. Another surgery, known as vitrectomy, can be done to remove cloudy fluid (vitreous humor) from the eye. | |

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 is (are) Multiple myeloma ? | Multiple myeloma is a form of cancer that occurs due to abnormal and uncontrolled growth of plasma cells in the bone marrow. Some people with multiple myeloma, especially those with early stages of the condition, have no concerning signs or symptoms. When present, the most common symptom is anemia, which can be associated with fatigue and shortness of breath. Other features of the condition may include multiple infections; abnormal bleeding; bone pain; weak and/or easily broken bones; and numbness and/or weakness of the arms and legs. The exact underlying cause of multiple myeloma is currently unknown. Factors that are associated with an increased risk of developing multiple myeloma include increasing age, male sex, African American race, radiation exposure, a family history of the condition, obesity, and/or a personal history of monoclonal gammopathy of undetermined significance (MGUS). Treatment varies based on many factors, but may include one or more of the following interventions: chemotherapy, corticosteroid medications, targeted therapy, stem cell transplant, biological therapy, radiation therapy, surgery and/or watchful waiting. | |

What causes Multiple myeloma ? | What causes multiple myeloma? Although the exact underlying cause of multiple myeloma is poorly understood, the specific symptoms of the condition result from abnormal and excessive growth of plasma cells in the bone marrow. Plasma cells help the body fight infection by producing proteins called antibodies. In people with multiple myeloma, excess plasma cells form tumors in the bone, causing bones to become weak and easily broken. The abnormal growth of plasma cells also makes it more difficult for the bone marrow to make healthy blood cells and platelets. The plasma cells produced in multiple myeloma produce abnormal antibodies that the immune system is unable to use. These abnormal antibodies build up in the body and cause a variety of problems. Factors that are associated with an increased risk of developing multiple myeloma include increasing age, male sex, African American race, radiation exposure, a family history of the condition, obesity, and/or a personal history of monoclonal gammopathy of undetermined significance (MGUS). | |
How to diagnose Multiple myeloma ? | How is multiple myeloma diagnosed? A diagnosis of multiple myeloma may be suspected based on the presence of characteristic signs and symptoms. Additional testing can then be ordered to confirm the diagnosis. This may include: Specialized blood tests including immunoglobulin studies, complete blood count with differential, and blood chemistry studies Urine tests such as immunoglobulin studies and a twenty-four-hour urine test Bone marrow aspiration and biopsy Imaging studies such as an X-ray of the bones (skeletal bone survey), MRI, CT scan, and/or PET scan The American Cancer Society offers more information regarding the diagnosis of multiple myeloma, including a summary of the many tests that may be recommended. Please click on the link to access this resource. Some affected people may have no suspicious signs or symptoms of multiple myeloma, especially in the early stages of the condition. In these cases, multiple myeloma is sometimes diagnosed by chance when a blood test or urine test is ordered to investigate another condition. | |
What are the treatments for Multiple myeloma ? | How might multiple myeloma be treated? The treatment of multiple myeloma varies based on many factors including the age and general health of the affected person; the associated signs and symptoms; and the severity of the condition. In general, one or more of the following interventions may be used to treat multiple myeloma: Chemotherapy Corticosteroid medications Targeted therapy Stem cell transplant Biological therapy Radiation therapy Surgery Watchful waiting The National Cancer Institute offers information regarding the management of multiple myeloma, including more specific information regarding the treatments outlined above.

What is (are) Trigeminal Trophic Syndrome ? | Trigeminal trophic syndrome is a rare disease that affects the skin on the side of the nose, supplied by the trigeminal nerve. People with trigeminal trophic syndrome have a loss of sensation in the nose or abnormal sensations like tingling, numbness, or burning and they rub or scratch the skin causing cuts or ulcers in the area. When the cuts heal, they can cause scars that pull up the lip. Similar cuts may also occur in the corners of the eyes, scalp or inside the mouth. The tip of the nose is spared because its sensation comes from a different nerve. Trigeminal trophic syndrome may occur in people who were treated for trigeminal neuralgia or after leprosy (Hansen's disease) or shingles infection. Treatment options include medications, radiotherapy, and covering the wounds until they have fully healed. Another treatment option is a technique called transcutaneous electrical stimulation that uses a small electronic device to direct mild electric pulses to nerve endings that lie beneath the skin. | |
What is (are) Pyruvate kinase deficiency ? | Pyruvate kinase deficiency is a genetic blood disorder characterized by low levels of an enzyme called pyruvate kinase, which is used by red blood cells. Without pyruvate kinase, red blood cells break down too easily, resulting in low levels of these cells (hemolytic anemia). The signs and symptoms of the disease may vary greatly from person to person. However, they usually include jaundice, enlargement of the spleen, and mild or severe hemolysis (red cell breakdown), leading to anemia. In some cases, the problems may first appear while in utero, causing a condition in which abnormal amounts of fluid build up in two or more body areas of the fetus (hydrops fetalis). Newborns may present with prolonged jaundice and anemia. Older children may be pale (due to anemia) and have intermittent episodes of jaundice. Mild cases may escape detection until adulthood. Although the anemia tends to stabilize in adulthood, episodes of anemia may occur with acute infections, stress, and pregnancy. Pyruvate kinase deficiency is caused by a mutation in the PKLR gene and is inherited in an autosomal recessive fashion. Treatment remains supportive rather than curative. | |
What are the symptoms of Pyruvate kinase deficiency ? | What are the signs and symptoms of Pyruvate kinase deficiency? The signs and symptoms of pyruvate kinase deficiency may vary greatly from person to person, but usually include the breakdown of red blood cells resulting in hemolytic anemia, a yellowing of the whites of the eyes (icterus), fatigue, lethargy, recurrent gallstones, jaundice, and pale skin (pallor). In more severe cases, the first signs and symptoms may appear in utero in the form of hydrops fetalis, a condition in which abnormal amounts of fluid build up in two or more body areas of the fetus. Newborns may present with prolonged jaundice and anemia. Older children may be pale (due to anemia) and have intermittent episodes of jaundice. Mild cases may escape detection until adulthood. Although the anemia tends to stabilize in adulthood, episodes of anemia may occur with acute infections, stress, and pregnancy.

What causes Pyruvate kinase deficiency ? | What causes pyruvate kinase deficiency? In most cases, pyruvate kinase deficiency is caused by mutations in the PKLR gene. More than 100 different mutation in the PKLR gene have been detected. Medical conditions, such as acute leukemia, preleukemia, and refractory sideroblastic anemia, as well as complications from chemotherapy, can cause an acquired pyruvate kinase deficiency. This type is more common and milder than the hereditary type. | |
Is Pyruvate kinase deficiency inherited ? | How is pyruvate kinase deficiency inherited? Pyruvate kinase deficiency is inherited in an autosomal recessive fashion, which means that a child must inherit a gene with a disease-causing mutation from both parents to develop the disorder. The gene that causes pyruvate kinase deficiency is called the PKLR gene that is located on chromosome 1q21. Although the inheritance is clinically autosomal recessive, most affected individuals are compound heterozygous for two different mutant alleles. It is estimated that approximatly 1 in 100 people carry one copy of a disease-causing mutation in the PKLR gene. Carriers of one non-working PKLR gene usually have moderatly reduced levels of pyruvate kinase activity but do not develop clinical symptoms. It is possible that carriers of a mutant pyruvate kinase genemay have a protective advantage against malaria in areas where the disease is endemic. | |
How to diagnose Pyruvate kinase deficiency ? | Is genetic testing available for pyruvate kinase deficiency? Yes. GeneTests lists laboratories offering clinical genetic testing for this condition. Clinical genetic tests are ordered to help diagnose an affected person or other family members and to aid in decisions regarding medical care or reproductive issues. We recommend that you talk to your health care provider or a genetic professional to learn more about your testing options. | |
What are the treatments for Pyruvate kinase deficiency ? | How might pyruvate kinase deficiency be treated? Mild cases require no treatment. People with severe anemia may need blood transfusions. In newborns with dangerous levels of jaundice, a health care provider may recommend an exchange transfusion. Surgical removal of the spleen (splenectomy) may also be necessary to help reduce the destruction of red blood cells. However, this does not help in all cases. With small children, this is delayed as long as possible to allow the immune system to mature. Other treatment is symptomatic and supportive. Someone who had a splenectomy should receive the pneumococcal vaccine at recommended intervals. They also should receive preventive antibiotics until age 5.

What is (are) Erythema nodosum, idiopathic ? | Erythema nodosum (EN) is a skin condition in which red bumps (nodules) form on the shins. Less commonly, the nodules form on other areas of the body such as the thighs and forearms. The lesions begin as firm, hot, red, painful lumps and progress to a purplish color. EN is a type of inflammatory disorder affecting the layer of fat under the skin (panniculitis). Other symptoms that may accompany the skin findings include the following: fever, a general feeling of being ill. joint aches, and swelling of the affected area. In many cases, EN is presumed to be a delayed reaction to antigens associated with various infections, drugs, and certain systemic diseases. In many cases, however, EN has no identifiable cause (idiopathic); in these cases, clinical follow-up is needed to rule out certain conditions including inflammatory bowel disease, sarcoidosis, lymphoma, and Behcet's disease. Treatment may include rest, nonsteroidal anti-inflammatory drugs (NSAIDS), steroids, hot or cold compresses, potassium iodide solution, and supportive bandages or compression stockings. Symptoms usually resolve within six weeks, but EN may become a chronic disorder lasting for months and, occasionally, for years. Approximately 30% cases of idiopathic EN may last more than 6 months. | |
What is (are) Wolman disease ? | Wolman disease is a type of lysosomal storage disorder. It is an inherited condition that causes a buildup of lipids (fats) in body organs and calcium deposits in the adrenal glands. Common symptoms in infants include enlarged liver and spleen, poor weight gain, low muscle tone, jaundice, vomiting, diarrhea, developmental delay, anemia, and poor absorption of nutrients from food. Wolman disease is caused by mutations in the LIPA gene. It is inherited in an autosomal recessive manner. The condition is severe and life-threatening, however new therapies, such as bone marrow transplantation, have shown promise in improving the outlook of children with this disease. Enzyme replacement therapy is also being developed. | |

What is (are) Charcot-Marie-Tooth disease type 1A ? | Charcot-Marie-Tooth disease type 1A (CMT1A) is a type of inherited neurological disorder that affects the peripheral nerves. Affected individuals experience weakness and wasting (atrophy) of the muscles of the lower legs beginning in adolescence; later they experience hand weakness and sensory loss. CMT1A is caused by having an extra copy (a duplication) of the PMP22 gene. It is inherited in an autosomal dominant manner. Treatment for this condition may include physical therapy; occupational therapy; braces and other orthopedic devices; orthopedic surgery; and pain medications. | |
What are the symptoms of Charcot-Marie-Tooth disease type 1A ? | What are the signs and symptoms of Charcot-Marie-Tooth disease type 1A? CMT1 is generally slowly progressive over many years. However, affected individuals often experience long periods without any obvious deterioration or progression. Occasionally, individuals show accelerated deterioration of function over a few years. Nerve conduction velocities (NCVs) tend to slow progressively over the first two to six years of life, but they appear to remain relatively stable throughout adulthood. Worsening of signs and symptoms tends to be slow in the second to fourth decades of life. It remains to be confirmed whether, and to what extent, there is clinical and electrophysiological disease progression in affected adults; two studies of adult with CMT1A have shown conflicting results. Authors of one study reported disease progression over time (23 years on average), while authors of another study found that both patients and controls (individuals without the condition) had a similar decline of strength and of electrophysiological findings. The findings in the latter study suggested that the decline in adulthood in affected individuals may reflect a process of normal aging rather than on-going active disease. Any major changes in the pace of progression may warrant consideration of additional acquired, or possibly independently inherited forms, of neuromuscular diseases. The severity of signs and symptoms of CMT1A can vary greatly among affected individuals. Individuals who have questions about their own specific signs and symptoms and how they may relate to progression of CMT should speak with their health care provider. The Human Phenotype Ontology provides the following list of signs and symptoms for Charcot-Marie-Tooth disease type 1A.

What is (are) Idiopathic acute eosinophilic pneumonia ? | Idiopathic acute eosinophilic pneumonia (IAEP) is characterized by the rapid accumulation of eosinophils in the lungs. Eosinophils are a type of white blood cell and are part of the immune system. IAEP can occur at any age but most commonly affects otherwise healthy individuals between 20 and 40 years of age. Signs and symptoms may include fever, cough, fatigue, difficulty breathing (dyspnea), muscle pain, and chest pain. IAEP can progress rapidly to acute respiratory failure. The term idiopathic means the exact cause for the overproduction of eosinophils is not known. Possible triggers of acute eosinophilic pneumonia include cigarette smoking, occupational exposure to dust and smoke, and certain medications. Diagnosis of IAEP generally involves a bronchoscopy and bronchoalveolar lavage (BAL). Treatment with corticosteroids is effective in most cases. Because IAEP often progresses rapidly, respiratory failure can occur; in these cases, mechanical ventilation is required. | |

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 is (are) Chromosome 7p deletion ? | Chromosome 7p deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the short arm (p) of chromosome 7. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved. Features that often occur in people with chromosome 7p deletion include developmental delay, intellectual disability, behavioral problems, and distinctive facial features. Most cases are not inherited, but people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person. |
