What causes Hereditary lymphedema type II ? | What causes hereditary lymphedema type II? The cause of hereditary lymphedema type II is unknown. The condition is thought to be genetic because it tends to run in families. Researchers have studied many genes associated with the lymphatic system; however, to date, no specific genetic change has been associated with this type of lymphedema. | |
Is Hereditary lymphedema type II inherited ? | How is hereditary lymphedema type II inherited? Hereditary lymphedema type II appears to have an autosomal dominant pattern of inheritance, which means that one copy of an altered gene in each cell is sufficient to cause the disorder. People with hereditary lymphedema type II usually have at least one other affected family member, in most cases, a parent. When the condition occurs in only one person in a family, the condition is described as Meige-like lymphedema. | |

What is (are) Anencephaly ? | Anencephaly is a type of neural tube defect characterized by abnormal development of the brain and the bones of the skull. The neural tube is a narrow channel that normally folds and closes between the 3rd and 4th weeks of pregnancy, forming the brain and spinal cord of the embryo. Anencephaly occurs when the 'cephalic' or head end of the neural tube fails to close, causing the absence of a major portion of the brain, skull, and scalp. Infants with this disorder are born without a forebrain (the front part of the brain) and a cerebrum (the thinking and coordinating part of the brain). The remaining brain tissue is often exposed (not covered by bone or skin). Affected babies are usually blind, deaf, unconscious, and unable to feel pain. Almost all babies with anencephaly die before birth, although some may survive a few hours or a few days after birth. Anencephaly is likely caused by an interaction between genetic and environmental factors, many of which remain unknown. | |

What causes Anencephaly ? | What causes anencephaly? The underlying cause of anencephaly is not fully understood. Like other forms of neural tube defects (NTDs), anencephaly is likely caused by the interaction of multiple genes and environmental factors, many of which remain unknown. Variations in many genes may influence the risk of developing anencephaly. The best-studied gene thus far is the MTHFR gene, which gives the body instructions to make a protein used to process the vitamin folate (also called vitamin B9). A deficiency of folate is a known risk factor for NTDs. Other genes involved in folate processing, and the development of the neural tube, may also affect the risk. Researchers have also looked at environmental factors that could contribute to the risk of anencephaly. Folate appears to play a significant role, and studies have shown that taking folic acid (a form of folate), before getting pregnant and very early in pregnancy, significantly reduces the risk to have a baby with a NTD. Other possible maternal risk factors for anencephaly include diabetes mellitus; obesity; exposure to high heat (such as a fever or use of a hot tub or sauna) in early pregnancy; and the use of certain anti-seizure medications during pregnancy. | |
Is Anencephaly inherited ? | Is anencephaly inherited? Most cases of anencephaly are sporadic, which means they occur in people with no family history of anencephaly or other neural tube defects (NTDs). In some cases, it may be associated with a chromosome abnormality, a severe malformation syndrome, or disruption of the amniotic membrane. A small portion of cases have appeared to be familial, but it often does not have a clear inheritance pattern. In isolated populations, anencephaly has been suspected to be due to a single gene. In Iranian Jews, who have high rates of consanguinity (mating with family members), it is inherited in an autosomal recessive manner. Parents who have had a child with anencephaly are at an increased risk to have another affected child (compared with the risk in the general population). Because most cases are believed to be multifactorial (due to interaction of genetic and environmental factors), the recurrence risk is estimated to be between 2% and 5% after a single case. If anencephaly is known to be associated with an underlying disorder, the recurrence risk may depend on that of the underlying disorder. For women who have previously had a fetus or infant with anencephaly, the Centers for Disease Control and Prevention (CDC) recommends increasing the intake of folic acid to 4mg per day beginning at least one month prior to conception. People who have had a pregnancy or child with anencephaly or another NTD, and have questions about future risk, are encouraged to speak with a genetic counselor or other genetics professional. | |
What is (are) Urachal cancer ? | Urachal cancer is a rare type of bladder cancer, making up less than 1% of all bladder cancers. Only about 350 cases have been described in the medical literature to date. The urachus is a primitive structure which before birth connected the bellybutton and the bladder. This connection normally disappears before birth, but in some people remains. Urachal cancers are classified as such based on location at the dome or anterior wall of the bladder and discovery of remnants of the urachus. Most urachal cancers are adenocarcinomas (cancers that develop from gland cells). Others may be sarcomas (which develop from connective tissue - such as leiomyosarcoma, rhabdomyosarcoma, and malignant fibrous histiocytoma), small cell carcinomas, transitional cell cancer, and mixed neoplasias. Most individuals with urachal cancer present with hematuria (blood in urine). Other symptoms may include abdominal pain, a palpable abdominal mass, mucinuria, and bacteriuria. Patients who present with early disease confined to the urachus have a good prognosis when treated with partial cystectomy, umbilicotomy, and urachal resection. The prognosis for those with advanced disease is less promising. | |
What are the treatments for Urachal cancer ? | How might urachal cancer be treated? Surgical resection in the form of partial (segmental) or radical cystoprostatectomy is the main form of treatment. However, similar results are seen with a conservative surgery that involves partial cystectomy with umbilicotomy and removal of the urachus. The role of chemotherapy and radiation therapy for the treatment of urachal cancer is unclear, although some studies show that chemotherapy can induce objective response in some cases. Chemotherapy regimens that may be used include: single-agent 5-fluorouracil (5-FU), 5-FU and cisplatin, 5-FU, lomustine and vincristine, taxol and cisplatin, platinum and etoposide, and MVAC (methotrexate, vinblastine, doxorubicin, cisplatin) alone or in conjunction with radiation therapy. | |

What is (are) Phacomatosis pigmentovascularis ? | Phacomatosis pigmentovascularis (PPV) is a skin and blood vessel disorder that is present from birth. Common signs and symptoms include port wine stain and pigmentary lesions, such as melanocytic nevi or epidermal nevi. A variety of classification systems have been proposed for PPV, largely depending on what type of pigmentary lesion is present. Around half of individuals with PPV have systemic disease, meaning that body systems other than the skin are affected. Systemic symptoms can vary greatly from person to person. PPV is not inherited, but is thought to be caused by a genetic phenomenon called twin spotting. | |
What are the symptoms of Phacomatosis pigmentovascularis ? | What are the signs and symptoms of phacomatosis pigmentovascularis? Characteristic signs and symptoms of phacomatosis pigmentovascularis (PPV), include port wine stain and pigmentary lesions. The port wine stain and pigmentary lesions are often extensive and can affect several areas of the body, including the face. Examples of associated pigmentary lesions, include: Melanocytic nevi Epidermal nevi In addition to the port wine stain and pigmentary lesions, other skin lesions are not uncommon, such as: Nevus anemicus Cafe-au-lait spots Mongolian spots Nevus of Ota Nevus of Ito Nevus spilus Around half of people with PPV have systemic involvement (i.e., other body systems are affected). Eye conditions such as ocular melanosis (also called ocular melanocytosis) is common. Ocular melanosis refers to a blue-gray pigmentation in the 'white of the eye' or sclerae. This condition often occurs along with nevus of Ota and may affect one or both eyes. The complications of nevus of Ota are glaucoma and melanoma, as a result people with nevus of Ota require careful examination and follow-up by an opthamologist. Other eye conditions reported in PPV include iris hamartomas, iris mammillations, and iris nodules. Some individuals with PPV also have Sturge-Weber syndrome or Klippel-Trenaunay syndrome. Signs and symptoms of Sturge-Weber syndrome include a large port-wine stain facial birthmark, blood vessel abnormalities in the brain called leptomeningeal angiomas, as well as glaucoma, seizures, muscle weakness, paralysis, developmental delay, and intellectual disability. Klippel-Trenaunay syndrome is characterized by a port-wine stain, abnormal overgrowth of soft tissues and bones, and vein malformations. You can learn more about Sturge-Weber syndrome on our Web site at the following link: http://rarediseases.info.nih.gov/GARD/Condition/7706/Sturge_Weber_syndrome.aspx You can learn more about Klippel-Trenaunay syndrome on the Genetic Home Reference Web site at the following link: http://ghr.nlm.nih.gov/condition/klippel-trenaunay-syndrome A variety of other symptoms have been reported in individual cases of PPV (e.g., primary lymphedema, renal angiomas, moyamoya disease, scoliosis, malignant colonic polyposis, hypoplastic larynx, multiple granular cell tumors, and selective IgA deficiency). Conditions associated with PPV can vary greatly from person to person and can be difficult to predict. | |
What causes Phacomatosis pigmentovascularis ? | What causes phacomatosis pigmentovascularis? Phacomatosis pigmentovascularis (PPV) is thought to occur as a result of a change in the arrangement of a small piece of genetic material in a developing embryo. Because of this change some of the baby's body cells carry two copies of recessive gene mutations while the majority of his or her body cells carry only one. Having two copies of the recessive gene mutations result in a diseased cell (and symptoms of PPV). This phenomenon is called twin spotting. PPV occurs by chance, it is not inherited, and affects only a subset of the body's cells. As a result risk to future offspring is very small. | |
How to diagnose Phacomatosis pigmentovascularis ? | How might phacomatosis pigmentovascularis be diagnosed? Diagnosis of phacomatosis pigmentovascularis is based primarily on physical evaluation and appearence of the skin lesions. | |
What are the treatments for Phacomatosis pigmentovascularis ? | How might phacomatosis pigmentovascularis be treated? If phacomatosis pigmentovascularis (PPV) is not associated with systemic complications (e.g., Sturge-Weber syndrome, Klippel-Trenaunay syndrome, eye conditions) it requires no treatment, however pulsed dye laser may improve the appearance of port wine stains and Q-switched laser the appearance of pigmentary nevus. Medical treatment of PPV with systemic complications requires individualized plans and often assistance from a team of specialists (e.g., opthamologist, neurologist, and vascular specialist). | |

What is (are) TARP syndrome ? | TARP syndrome is a rare condition affecting males that causes several birth defects. TARP stands for Talipes equinovarus, Atrial septal defect, Robin sequence, and Persistent left superior vena cava. Those with TARP syndrome have clubfoot deformity (talipes equinovarus) and congenital heart defects involving failure of the upper heart chambers to close (atrial septal defect). The Robin sequence (also known as Pierre Robins sequence) is characterized by a small lower jaw at birth that prevents proper feeding of the infant, followed by a retracted or displaced tongue. A high-arched, cleft soft palate is also commonly seen. Affected individuals also have persistent left superior vena cava. TARP syndrome has been reported to cause death before birth or soon after birth. This condition is caused by mutations in the RBM10 gene and is inherited in an X-linked recessive fashion. | |
What are the symptoms of TARP syndrome ? | What are the signs and symptoms of TARP syndrome? TARP is an acronym for the 4 main features that were present in individuals originally diagnosed with TARP syndrome: Talipes equinovarus (clubfoot) Atrial septal defect (ASD) - a heart defect at birth characterized by failure of an opening of the upper heart chambers to close Robin sequence Persistence of the left superior vena cava (SVC). More recently, some affected individuals (confirmed by genetic testing) have been described having a more diverse range of signs and symptoms. Two boys from one family with TARP syndrome were born without clubfoot, but had additional features including polydactyly (additional fingers and/or toes); cutaneous syndactyly (webbing of the skin between the fingers and/or toes); and masses on the underside of the tongue (sublingual tongue masses). An individual in another family had only one of the 4 main features. An individual in a third family had only 2 of the 4 features of TARP. Additional abnormalities that have been reported in the medical literature in affected individuals include failure to thrive; abnormal skull shape; round face; short palpebral fissures (decreased width of each eye); small or abnormally-shaped ears; poor muscle tone (hypotonia); developmental delay; eye or visual abnormalities; hearing loss; airway or lung abnormalities; undescended testicles (cryptorchidism); structural brain abnormalities; and intellectual disability. Most affected males have died before birth or shortly after birth. However, in 2011 there was a report of an affected individual who was 3 years, 7 months old and was surviving with intensive medical care. The authors of this report concluded that long-term survival is possible for individuals with TARP syndrome and that older affected individuals may exist.

What causes TARP syndrome ? | What causes TARP syndrome? TARP syndrome is a genetic condition caused by mutations in the RBM10 gene, which is located on the X chromosome. There is little information available about how mutations in this gene specifically cause TARP syndrome. However, in 2010 researchers showed that the RBM10 gene is expressed in mouse embryos in the branchial arches (embryonic structures that give rise to parts of the head and neck) and limbs, which is consistent with body parts known to be affected in individuals with TARP syndrome. The signs and symptoms of TARP syndrome occur when this gene does not function correctly. | |
Is TARP syndrome inherited ? | How is TARP syndrome inherited? TARP syndrome is inherited in an X-linked recessive manner. This means that the mutated gene responsible for TARP syndrome (RBM10) is located on the X chromosome, and typically only affects males. Males have one X chromosome and one Y chromosome, while females have two X chromosomes. If a female has one mutated copy of RBM10 and one normal copy, she would typically be an unaffected carrier of this condition. Occasionally, female carriers of an X-linked recessive condition may have varying degrees of signs or symptoms of the condition; this is due to differences in X chromosome inactivation. When a female carrier of an X-linked condition has children, each daughter has a 50% (1 in 2) risk to also be a carrier, and a 50% risk to not be a carrier (and have 2 normal copies of the gene). Each son has a 50% risk to be affected and a 50% risk to be unaffected. | |
How to diagnose TARP syndrome ? | Is genetic testing available for TARP syndrome? Yes, genetic testing (including carrier testing) is available for TARP syndrome. The Genetic Testing Registry (GTR) provides information about the labs that offer genetic testing for this condition. On the GTR Web site, click on the title "Test for TARP syndrome" to find out more information about each test. The intended audience for the GTR is health care providers and researchers. Therefore, patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. | |

What is (are) Thrombotic thrombocytopenic purpura, congenital ? | Thrombotic thrombocytopenic purpura (TTP), congenital is a blood disorder characterized by low platelets (i.e., thrombocytopenia), small areas of bleeding under the skin (i.e., purpura), low red blood cell count, and hemolytic anemia. TTP causes blood clots (thrombi) to form in small blood vessels throughout the body. These clots can cause serious medical problems if they block vessels and restrict blood flow to organs such as the brain, kidneys, and heart. Resulting complications can include neurological problems (such as personality changes, headaches, confusion, and slurred speech), fever, abnormal kidney function, abdominal pain, and heart problems. Hemolytic anemia can lead to paleness, yellowing of the eyes and skin (jaundice), fatigue, shortness of breath, and a rapid heart rate. TTP, congenital is much rarer than the acquired form and typically appears in infancy or early childhood. Signs and symptoms often recur on a regular basis. TTP, congenital results from mutations in the ADAMTS13 gene. The condition is inherited in an autosomal recessive manner. | |

What is (are) Tietze syndrome ? | Tietze syndrome is an inflammatory condition characterized by chest pain and swelling of the cartilage that joins the upper ribs to the breastbone (costochondral junction). Signs and symptoms of this condition usually develop in young adults (before age 40) and include mild to severe chest pain that may extend into the arms and/or shoulders. The cause of this condition is unknown. In some cases, Tietze syndrome may resolve on its own without treatment. Management for others may include minimizing physical activity; applying local heat; and taking pain medications and/or nonsteroidal anti-inflammatory drugs. Of note, this syndrome is different from Tietz syndrome, which is characterized by profound hearing loss from birth, fair skin, and light-colored hair. | |
What are the symptoms of Tietze syndrome ? | What are the signs and symptoms of Tietze syndrome? The signs and symptoms of Tietze syndrome usually develop in young adulthood (before age 40). The most common symptom is mild to severe chest pain that may extend into the arms and/or shoulders. The onset of pain can be gradual or sudden and may worsen with coughing, sneezing, or deep breathing. More than 70% of cases occur on only one side (unilateral) and affect one joint. The affected joint is typically tender and swollen. While the pain associated with Tietze syndrome usually subsides after several weeks or months, the swelling may persist. | |

How to diagnose Tietze syndrome ? | How is Tietze syndrome diagnosed? Tietze syndrome is a diagnosis of exclusion. This means that a diagnosis is made in people with chest pain and swelling of the cartilage that joins the upper ribs to the breastbone (costochondral junction) after other conditions with similar signs and symptoms have been ruled out. A thorough physical exam and various tests (i.e. electrocardiogram, x-ray, CT scan) may be necessary to exclude other conditions. | |
What are the treatments for Tietze syndrome ? | How might Tietze syndrome be treated? In some individuals, the pain associated with Tietze syndrome resolves on its own without any treatment. Management options for others may include avoidance of strenuous activity; applying local heat; taking pain medications and/or nonsteroidal anti-inflammatory drugs; and receiving local corticosteroid injections. Although the pain usually subsides after several weeks or months, swelling may persist. | |
What is (are) Progeria ? | Progeria is a rare condition characterized by dramatic, rapid aging beginning in childhood. Affected newborns usually appear normal but within a year, their growth rate slows significantly. Affected children develop a distinctive appearance characterized by baldness, aged-looking skin, a pinched nose, and a small face and jaw relative to head size. They also often have symptoms typically seen in much older people including joint stiffness, hip dislocations and severe, progressive cardiovascular disease. Intelligence is typically normal. The average lifespan is age 13-14; death is usually due to heart attack or stroke. Progeria is caused by mutations in the LMNA gene, but almost always results from a new mutation rather than being inherited from a parent. Management focuses on the individual signs and symptoms of the condition. Although there is currently no cure, research involving treatment is ongoing and progress is being made. | |

What causes Progeria ? | What genes are related to Hutchinson-Gilford progeria syndrome? Mutations in the LMNA gene cause Hutchinson-Gilford progeria syndrome. The LMNA gene provides instructions for making a protein called lamin A. This protein plays an important role in determining the shape of the nucleus within cells. It is an essential scaffolding (supporting) component of the nuclear envelope, which is the membrane that surrounds the nucleus. Mutations that cause Hutchinson-Gilford progeria syndrome result in the production of an abnormal version of the lamin A protein. The altered protein makes the nuclear envelope unstable and progressively damages the nucleus, making cells more likely to die prematurely. Researchers are working to determine how these changes lead to the characteristic features of Hutchinson-Gilford progeria syndrome. | |
What are the treatments for Progeria ? | How might progeria be treated? Management for progeria generally focuses on the signs and symptoms of the condition and may include the following: Exercise, diet modification, and medication when the lipid profile becomes abnormal Frequent small meals to maximize caloric intake Oral hydration Use of shoe pads for foot discomfort due to lack of body fat Use of sunscreen on all exposed areas of skin Nitroglycerin for angina Routine anticongestive therapy if congestive heart failure is present Statins for their putative effect on farnesylation inhibition Anticoagulation therapy if vascular blockage, transient ischemic attacks, stroke, angina, or heart attack occur Routine physical and occupational therapy to help maintain range of motion in large and small joints Although there is currently no cure for progeria, research involving treatments is ongoing and scientists have been making much progress. The results of a recently published phase II clinical trial provided preliminary evidence that lonafarnib, a farnesyltransferase inhibitor, may improve cardiovascular status, bone structure, and audiological (hearing) status in affected children.

What is (are) Adenylosuccinase deficiency ? | Adenylosuccinase deficiency is a rare, inherited metabolic condition that results from a lack of the enzyme adenylosuccinate lyase. Signs and symptoms vary greatly from person to person. In general, affected individuals may have a mix of neurological symptoms, which usually includes abnormalities with cognition and movement, autistic features, epilepsy, muscle wasting, and feeding problems. Although less common, abnormal physical features can include severe growth failure, small head, abnormally shaped head, strabismus, small nose with upturned nostrils, thin upper lip, and low set ears. Adenylosuccinase deficiency is caused by mutations in the ADSL gene and is inherited in an autosomal recessive fashion. | |
What are the symptoms of Adenylosuccinase deficiency ? | What are the signs and symptoms of Adenylosuccinase deficiency? The signs and symptoms of adenylosuccinase deficiency vary greatly from person to person. Seizures are observed in 60 percent of affected individuals. Seizures may begin within the first month of life and, in many cases, are the first sign of the condition. Some of the neurological symptoms include floppiness (hypotonia) with severe tension of the hands and feet (hypertonia); muscle wasting; muscle twitchings of the tongue or hands and feet; and crossed eyes (strabismus). Almost all affected individuals experience delayed motor milestones ranging from mild to severe. In the first years of life, growth delay has been observed in 30 percent of affected individuals, mainly related to feeding problems. Autism has been found to be present in one-third of cases. Some children display unusual behavior such as stereotyped behavior, (hand washing movements, repetitive manipulation of toys, grimacing, clapping hands, rubbing feet, and inappropriate laughter), aggressive behavior, temper tantrums, impulsivity, hyperactivity, short attention span, and hypersensitivity to noise and lights.

What is (are) Variant Creutzfeldt-Jakob disease ? | There are several known variants of Creutzfeldt-Jakob disease (CJD). These variants differ somewhat in the symptoms and course of the disease. For example, a variant form of the disease-called new variant or variant (nv-CJD, v-CJD), described in Great Britain and France, begins primarily with psychiatric symptoms, and has a longer than usual duration from onset of symptoms to death. New variant CJD accounts for less than 1% of cases, and tends to affect younger people. It can result when someone is exposed to contaminated products. While classic CJD is not related to mad cow disease, new variant CJD (nvCJD) is an infectious form that is related to mad cow disease. The infection responsible for the disease in cows (bovine spongiform encephalitis) is believed to be the same one responsible for vCJD in humans. There have not been any cases of nvCJD reported in the U.S. Another variant, called the panencephalopathic form, occurs primarily in Japan and has a relatively long course, with symptoms often progressing for several years. Scientists are trying to gain a better understanding about what causes these variations in the symptoms and course of the disease. | |

What is (are) Lentigo maligna melanoma ? | Lentigo maligna melanoma (LMM) is a type of skin cancer that usually develops in older, fair-skinned adults. The average age of diagnosis is 65. LMM is thought to be caused by a history of sun exposure to the affected area. Treatment includes surgery to remove as much of the LMM as possible. | |
What is (are) Glioblastoma ? | Glioblastoma is a malignant (cancerous) brain tumor that develops from a specific type of brain cell called an astrocyte. These cells help support and nourish neurons (nerve cells of the brain) and form scar tissue that helps repair brain damage in response to injury. Glioblastomas are often very aggressive and grow into surrounding brain tissue. Signs and symptoms, such as headache, nausea, vomiting and/or drowsiness, may develop when the tumor begins to put excess pressure on the brain. Affected people may also experience other features depending on the size and location of the tumor. In most cases, the exact underlying cause is unknown; however, they can rarely occur in people with certain genetic syndromes such as neurofibromatosis type 1, Turcot syndrome and Li Fraumeni syndrome. There is currently no cure for glioblastoma. Treatment is palliative and may include surgery, radiation therapy and/or chemotherapy. | |
What are the symptoms of Glioblastoma ? | What are the signs and symptoms of glioblastoma? Signs and symptoms of glioblastoma vary depending on the size and location of the tumor but may include: Headache Nausea and vomiting Drowsiness Changes in personality Weakness on one side of the body Memory loss Speech difficulty Changes in vision Seizures | |
What causes Glioblastoma ? | What causes glioblastoma? In most cases, the exact underlying cause of glioblastoma is unknown. In rare cases, they can occur in people with certain genetic syndromes such as neurofibromatosis type 1, Turcot syndrome and Li Fraumeni syndrome. In these cases, affected people usually have other characteristic features of the condition that are all caused by changes (mutations) in a specific gene. | |
Is Glioblastoma inherited ? | Is glioblastoma inherited? Most glioblastomas are not inherited. They usually occur sporadically in people with no family history of tumors. However, they can rarely occur in people with certain genetic syndromes such as neurofibromatosis type 1, Turcot syndrome and Li Fraumeni syndrome. All of these conditions are inherited in an autosomal dominant manner. | |
How to diagnose Glioblastoma ? | Is genetic testing available for glioblastoma? Genetic testing is not available for many people with glioblastoma since most of these tumors occur sporadically (by chance) and are not caused by a genetic mutation. However, genetic testing is an option for people with an inherited condition that predisposes to glioblastoma such as neurofibromatosis type 1, Turcot syndrome and Li Fraumeni 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. It provides a list of laboratories performing genetic testing for neurofibromatosis type 1, Turcot syndrome and Li Fraumeni syndrome. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional. How is glioblastoma diagnosed? Glioblastoma is typically diagnosed based on a physical exam that identifies characteristic symptoms and various imaging studies such as computed tomography (CT) and/or magnetic resonance imaging (MRI). A CT scan is an imaging method that uses x-rays to create pictures of cross-sections of the body, while an MRI scan uses powerful magnets and radio waves to create pictures of the brain and surrounding nerve tissues. These imaging studies will also provide information regarding the size of the tumor and which parts of the brain are affected. Surgical removal of the tumor or a small biopsy may confirm the diagnosis. | |
What are the treatments for Glioblastoma ? | How might glioblastoma be treated? Unfortunately, there is no cure for glioblastoma. Treatment is palliative and may include surgery, radiation therapy and/or chemotherapy. The best treatment options for each person depend on many factors including the size and location of the tumor; the extent to which the tumor has grown into the surrounding normal brain tissues; and the affected person's age and overall health. Glioblastoma is often treated with surgery initially to remove as much of the tumor as possible. In most cases, it is not possible to remove the entire tumor so additional treatment with radiation therapy and/or chemotherapy is necessary. In elderly people or people in whom surgery is not an option, radiation therapy and/or chemotherapy may be used. | |
What is (are) Split hand/foot malformation X-linked ? | 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 is (are) Lipodermatosclerosis ? | Lipodermatosclerosis refers to changes in the skin of the lower legs. It is a form of panniculitis (inflammation of the layer of fat under the skin). Signs and symptoms include pain, hardening of skin, change in skin color (redness), swelling, and a tapering of the legs above the ankles. The exact underlying cause is unknown; however, it appears to be associated with venous insufficiency and/or obesity. Treatment usually includes compression therapy. | |
What are the symptoms of Lipodermatosclerosis ? | What are the signs and symptoms of lipodermatosclerosis? Lipodermatosclerosis refers to changes in the skin of the lower legs. One or both legs may be involved. Signs and symptoms vary but may include: Pain Hardening and/or thickening of the skin Varicose veins Changes in skin color (redness) Small white scarred areas (atrophie blanche) Swelling Leg ulcers Tapering of the legs above the ankles | |
What causes Lipodermatosclerosis ? | What causes lipodermatosclerosis? The exact cause of lipodermatosclerosis is unknown; however, it may be related to certain vein abnormalities and/or obesity. Lipodermatosclerosis often occurs in people with venous insufficiency. Approximately two thirds of affected people are obese. | |
How to diagnose Lipodermatosclerosis ? | How is lipodermatosclerosis diagnosed? Lipodermatosclerosis is usually diagnosed based on the presence of characteristic signs and symptoms. A skin biopsy and/or blood tests are usually not required to confirm a diagnosis but may be performed in rare cases. Ultrasound scans and/or magnetic resonance imaging (MRI) may be used to obtain more information regarding the severity of the condition and to determine the best treatment approach. | |
What are the treatments for Lipodermatosclerosis ? | How might lipodermatosclerosis be treated? Lipodermatosclerosis is primarily treated with compression therapy to improve venous insufficiency. Other strategies for managing venous insufficiency include leg elevation; not sitting or standing in one place for long periods of time; regular exercise; and weight loss if overweight or obese. Some affected people may require medications to prevent blood clotting; reduce pain and inflammation; and/or increase blood flow. Depending on the severity of the condition and the response to initial treatments, vein surgery may be recommended. | |
What is (are) Prothrombin thrombophilia ? | Prothrombin thrombophilia is an inherited disorder of blood clotting. Thrombophilia is an increased tendency to form abnormal blood clots in blood vessels. People who have prothrombin thrombophilia are at somewhat higher than average risk for a type of clot called a deep venous thrombosis, which typically occur in the deep veins of the legs. Affected people also have an increased risk of developing a pulmonary embolism. However, most people with prothrombin thrombophilia never develop abnormal blood clots. Prothrombin thrombophilia is the second most common inherited form of thrombophilia after factor V Leiden thrombophilia. It is more common in Caucasian populations. This condition is caused by a particular mutation (written G20210A or 20210G>A) in the F2 gene. People can inherit one or two copies of the gene mutation from their parents. | |
What are the symptoms of Prothrombin thrombophilia ? | What are the signs and symptoms of Prothrombin thrombophilia? The signs and symptoms of this condition depend on whether a person has inherited one or two copies of the F2 gene mutation from his or her parents. A person who inherits one gene mutation is called a heterozygote. Whereas a person that inherits two gene mutations (one from each parent) is considered a homozygote for this condition; although it is very rare to find individuals who are homozygous. An affected heterozygous person usually experiences mild to moderate increase in their thrombin production, which is associated with 2.5 to 3 fold greater risk of developing a venous thromboembolism. There is not enough information about risk in those who are homozygous. Some research suggests that in women, prothrombin thrombophilia is associated with a somewhat increased risk of pregnancy loss (miscarriage) and may also increase the risk of other complications during pregnancy. These complications may include pregnancy-induced high blood pressure (preeclampsia), slow fetal growth, and early separation of the placenta from the uterine wall (placental abruption). It is important to note, however, that most women with prothrombin thrombophilia have normal pregnancies. The Human Phenotype Ontology provides the following list of signs and symptoms for Prothrombin thrombophilia. If the information is available, the table below includes how often the symptom is seen in people with this condition.

Is Prothrombin thrombophilia inherited ? | How is prothrombin thrombophilia inherited? Prothrombin thrombophilia is inherited in an autosomal dominant manner. For this condition, this means that having one mutated copy of the disease-causing gene (F2) in each cell may be sufficient to cause signs or symptoms of the condition. The mutation in the F2 gene that causes prothrombin thrombophilia is called 20210G>A (also called the 20210G>A allele). An individual can be heterozygous (having the mutation in only one copy of the F2 gene) or homozygous (having a mutation in both copies of the F2 gene). Heterozygosity results in an increased risk for thrombosis; homozygosity results in more severe thrombophilia and/or increased risk for thrombosis. All individuals reported to date with prothrombin thrombophilia who are heterozygous for the 20210G>A allele have had an affected parent. Because of the relatively high prevalence of this allele in the general population, occasionally one parent is homozygous or both parents are heterozygous for this allele. When an individual who is heterozygous for the 20210G>A allele has children, each child has a 50% (1 in 2) risk to inherit that allele and also be heterozygous. An individual who is homozygous will always pass one of the 20210G>A alleles to each of his/her children. If two heterozygotes have children together, each child has a 25% (1 in 4) risk to be homozygous (having 2 mutated copies), a 50% risk to be heterozygous like each parent, and a 25% risk to inherit 2 normal copies of the F2 gene. | |
How to diagnose Prothrombin thrombophilia ? | What kind of tests can determine if an individual has, or is a carrier of, prothrombin thrombophilia? No clinical signs or symptoms are specific for prothrombin thrombophilia. A confirmed diagnosis of this condition requires specific genetic testing via DNA analysis of the F2 gene, which provides instructions for making the protein prothrombin. The test identifies the presence of a common change (mutation) called 20210G>A. An individual can be a heterozygote (having one mutated copy of the F2 gene) or a homozygote (having two mutated copies). Most heterozygotes have a mildly elevated plasma concentration of prothrombin (which can be measured in a blood test) that is approximately 30% higher than normal. However, these values can vary greatly, and the range of prothrombin concentrations in heterozygotes overlaps significantly with the normal range. Therefore, plasma concentration of prothrombin is not reliable for diagnosis of this condition. Individuals interested in learning more about testing for prothrombin thrombophilia should speak with a genetics professional or other healthcare provider. | |

What is (are) Nonspherocytic hemolytic anemia due to hexokinase deficiency ? | Nonspherocytic hemolytic anemia due to hexokinase deficiency (NSHA due to HK1 deficiency) is a very rare condition mainly characterized by severe, chronic hemolysis, beginning in infancy. Approximately 20 cases of this condition have been described to date. Signs and symptoms of hexokinase deficiency are very similar to those of pyruvate kinase deficiency but anemia is generally more severe. Some affected individuals reportedly have had various abnormalities in addition to NSHA including multiple malformations, panmyelopathy, and latent diabetes. It can be caused by mutations in the HK1 gene and is inherited in an autosomal recessive manner. Treatment may include red cell transfusions for those with severe anemia. | |
What are the symptoms of Nonspherocytic hemolytic anemia due to hexokinase deficiency ? | What are the signs and symptoms of Nonspherocytic hemolytic anemia due to hexokinase deficiency? Hexokinase deficiency manifests itself primarily as nonspherocytic hemolytic anemia (NSHA). The signs and symptoms of hexokinase deficiency are very similar to those of pyruvate kinase deficiency, a more common inherited cause of hemolytic anemia, and may include jaundice, fatigue, lethargy, and pale skin.. However, the anemia associated with hexokinase deficiency is generally more severe. There have been reports of some affected individuals having various other abnormalities including multiple malformations, panmyelopathy, and latent diabetes. The Human Phenotype Ontology provides the following list of signs and symptoms for Nonspherocytic hemolytic anemia due to hexokinase deficiency.

What causes Nonspherocytic hemolytic anemia due to hexokinase deficiency ? | What causes nonspherocytic hemolytic anemia due to hexokinase deficiency? Nonspherocytic hemolytic anemia due to hexokinase deficiency has been shown to be caused by mutations in the HK1 gene, which cause at least a partial deficiency of the enzyme hexokinase. This enzyme plays an important role in the chemical processes involved in the breakdown of sugar molecules (glycolysis). Red blood cells depend on this process for energy; if an enzyme is defective in any one of the stages, the red blood cell cannot function properly and hemolysis takes place. When red blood cells cannot be replaced faster than they destroy themselves, anemia results. | |
Is Nonspherocytic hemolytic anemia due to hexokinase deficiency inherited ? | How is nonspherocytic hemolytic anemia due to hexokinase deficiency inherited? Nonspherocytic hemolytic anemia due to hexokinase deficiency is inherited in an autosomal recessive manner. This means that a mutation in both copies of the gene associated with the condition must be present in order to be affected. The parents of an individual with an autosomal recessive condition each have one mutated copy of the gene in each cell and are referred to as carriers. Carriers typically do not have any signs or symptoms of the condition. When two carriers of the same autosomal recessive condition have children, each child has a 25% (1 in 4) risk to be affected, a 50% (1 in 2) risk to be an unaffected carrier like each parent, and a 25% risk to be unaffected and have 2 normal copies of the gene. | |
What are the treatments for Nonspherocytic hemolytic anemia due to hexokinase deficiency ? | How might nonspherocytic hemolytic anemia due to hexokinase deficiency be treated? When severe anemia is present, blood transfusions may be necessary. Affected individuals should avoid any drugs that can cause destruction of red blood cells, as well as any environmental triggers that may be identified. | |

What is (are) Autoimmune hepatitis ? | Autoimmune hepatitis is a disease in which the bodys immune system attacks liver cells. This immune response causes inflammation of the liver, also called hepatitis. The disease can be quite serious and, if not treated, gets worse over time, leading to cirrhosis of the liver and/or liver failure. Autoimmune hepatitis sometimes occurs in relatives of people with autoimmune diseases, suggesting a genetic cause. This disease is most common in young girls and women. |
