How to diagnose GM1 gangliosidosis ? 

Is genetic testing available for GM1 gangliosidosis? Yes. A diagnosis of GM1 gangliosidosis (GM1), can be made by either enzyme analysis of the beta-galactosidase enzyme, or by molecular genetic testing of the GLB1 gene. Despite the availability of molecular genetic testing, the mainstay of diagnosis will likely continue to be enzyme activity because of cost and difficulty in interpreting unclear results. However, enzyme activity may not be predictive of carrier status in relatives of affected people. Carrier testing for at-risk family members is done with molecular genetic testing, and is possible if the disease-causing mutations in the family are already known. The Genetic Testing Registry (GTR) provides information about the labs that offer genetic testing for this condition. 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 are the treatments for GM1 gangliosidosis ? 

How might GM1 gangliosidosis be treated? There is currently no effective medical treatment for GM1 gangliosidosis. Symptomatic treatment for some of the neurologic signs and symptoms is available, but does not significantly alter the progression of the condition. For example, anticonvulsants may initially control seizures. Supportive treatments may include proper nutrition and hydration, and keeping the affected individual's airway open. Bone marrow transplantation was reportedly successful in an individual with infantile/juvenile GM1 gangliosidosis; however, no long-term benefit was reported. Presymptomatic cord-blood hematopoietic stem-cell transplantation has been advocated by some as a possible treatment due to its success in other lysosomal storage disorders. Active research in the areas of enzyme replacement and gene therapy for the condition is ongoing but has not yet advanced to human trials. Neurologic and orthopedic sequelae may prevent adequate physical activity, but affected individuals may benefit from physical and occupational therapy.
What is (are) GRACILE syndrome ? 

GRACILE syndrome is an inherited metabolic disease. GRACILE stands for growth retardation, aminoaciduria, cholestasis, iron overload, lactacidosis, and early death. Infants are very small at birth and quickly develop life-threatening complications. During the first days of life, infants will develop a buildup of lactic acid in the bloodstream (lactic acidosis) and amino acids in the urine (aminoaciduria). They will also have problems with the flow of bile from the liver (cholestasis) and too much iron in their blood. Affected individuals arent typically born with unique physical features. Although alkali therapy is used as treatment, about half of affected infants do not survive past the first days of life. Those that do survive this period generally do not live past 4 months despite receiving treatment. GRACILE syndrome is caused by a mutation in the BCS1L gene, and it is inherited in an autosomal recessive pattern. The BCS1L gene provides instructions needed by the mitochondria in cells to help produce energy.

What is (are) Hemophilia ? 

Hemophilia is a bleeding disorder that slows the blood clotting process. People with this disorder experience prolonged bleeding following an injury, surgery, or having a tooth pulled. In severe cases, heavy bleeding occurs after minor trauma or in the absence of injury. Serious complications can result from bleeding into the joints, muscles, brain, or other internal organs. The major types of this disorder are hemophilia A and hemophilia B. Although the two types have very similar signs and symptoms, they are caused by mutations in different genes. People with an unusual form of hemophilia B, known as hemophilia B Leyden, experience episodes of excessive bleeding in childhood, but have few bleeding problems after puberty. Another form of the disorder, acquired hemophilia, is not caused by inherited gene mutations.

What is (are) WaterhouseFriderichsen syndrome ? 

WaterhouseFriderichsen syndrome is adrenal gland failure due to bleeding into the adrenal gland. It is usually caused by severe meningococcal infection or other severe, bacterial infection. Symptoms include acute adrenal gland insufficiency, and profound shock. Most patients with this condition are children, although adults may rarely be affected. It is deadly if not treated immediately.
What are the symptoms of WaterhouseFriderichsen syndrome ? 

What are the symptoms of Waterhouse-Friderichsen syndrome? Waterhouse-Friderichsen syndrome is characterized by the abrupt onset of fever, petechiae, septic shock, and disseminated intravascular coagulation (DIC) followed by acute hemorrhagic necrosis of the adrenal glands and severe cardiovascular dysfunction. Patients often experience prodromic, nonspecific symptoms, including malaise, headache, weakness, dizziness, cough, arthralgia (joint pain), and myalgia (muscle pain).  A characteristic skin rash with a typical evolution occurs in approximately 75% of patients with Waterhouse-Friderichsen syndrome. In its early stages, the rash consists of small, pink macules or papules. These are rapidly followed by petechial lesions, which gradually transform into large, purpuric, coalescent plaques in late stages of the disease.
What causes WaterhouseFriderichsen syndrome ? 

What causes Waterhouse-Friderichsen syndrome? Waterhouse-Friderichsen syndrome is most often associated with meningococcal disease (accounts for 80% of cases). The syndrome also has been associated with other bacterial pathogens, including Streptococcus pneumoniae, group A beta-hemolytic streptococci, Neisseria gonorrhoeae, Escherichia coli, Klebsiella pneumoniae, Haemophilus influenzae (group B), Salmonella choleraesuis, Pasteurella multocida, Acinetobacter calcoaceticus, and Plesiomonas shigelloides. It may also be associated with a history of splenectomy. In rare cases, it may be caused by the use of medications that promote blood clotting, low platelet counts, primary antiphospholipid syndrome, renal vein thrombosis or steroid use. While the exact mechanism of disease is not clear, activation of several cytokine mediators appears to lead to sepsis and shock.
What are the treatments for WaterhouseFriderichsen syndrome ? 

How might Waterhouse-Friderichsen syndrome be treated? Treatment may include antibiotics and glucocorticoids.  Other treatment is symptomatic and supportive.
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) Lenz microphthalmia syndrome ? 

Lenz microphthalmia syndrome is a genetic disorder that causes abnormal development of the eyes and several other parts of the body.  Eye symptoms vary, but may include underdeveloped (small) or absent eyes, cataract, nystagmus, coloboma (a gap or split in structures that make up the eye), and glaucoma. Eye symptoms may affect one or both eyes and may cause vision loss or blindness.  Other signs and symptoms may include abnormalities of the ears, teeth, hands, skeleton, urinary system and occasionally heart defects.  Around 60% of people with this condition have delayed development or intellectual disability ranging from mild to severe. Mutations in the BCOR gene cause some cases of Lenz microphthalmia syndrome. The other causative gene(s) have yet to be identified. This condition is inherited in an X-linked recessive fashion.
What is (are) Denys-Drash syndrome ? 

Denys-Drash syndrome is a condition that affects the kidneys and genitalia. Kidney disease typically begins in the first few months of life, often leading to kidney failure in childhood. In addition, up to 90 percent of people with this condition develop a rare form of kidney cancer known as Wilms tumor. Males with Denys-Drash syndrome have gonadal dysgenesis, a condition in which the external genitalia do not look clearly male or clearly female (ambiguous genitalia) or the genitalia appear to be completely female. The testes are also undescended, meaning that they remain in the pelvis, abdomen, or groin. Affected females usually have normal genitalia. For this reason, females with this condition may be diagnosed with isolated nephrotic syndrome. Denys-Drash syndrome is caused by mutations in the WT1 gene. This condition is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. However, most cases result from new mutations in the gene and occur in people with no history of the disorder in their family.
What are the symptoms of Denys-Drash syndrome ? 

What are the signs and symptoms of Denys-Drash syndrome? The Human Phenotype Ontology provides the following list of signs and symptoms for Denys-Drash syndrome.

In these cases, the sign or symptom may be rare or common.
What causes Denys-Drash syndrome ? 

What causes Denys-Drash syndrome? Denys-Drash syndrome is caused by mutations in the WT1 gene. This gene provides instructions for making a protein (the WT1 protein) that regulates the activity of other genes by attaching (binding) to specific regions of DNA. The WT1 protein plays a role in the development of the kidneys and gonads (ovaries in females and testes in males) before birth. The WT1 gene mutations that cause Denys-Drash syndrome lead to the production of an abnormal protein that cannot bind to DNA. As a result, the activity of certain genes is unregulated, which impairs the development of the kidneys and reproductive organs. Abnormal development of these organs leads to diffuse glomerulosclerosis (where scar tissue forms throughout glomeruli, the tiny blood vessels in the kidney that filter waste from blood) and gonadal dysgenesis, which are characteristic features of Denys-Drash syndrome. The abnormal gene activity caused by the loss of normal WT1 protein also increases the risk of developing Wilms tumor in affected individuals.
Is Denys-Drash syndrome inherited ? 

Is Denys-Drash syndrome inherited? Denys-Drash syndrome is inherited in an autosomal dominant pattern, which means one copy of the altered gene in each cell is sufficient to cause the disorder. Most cases of Denys-Drash syndrome result from new (de novo) mutations in the gene that occur during the formation of reproductive cells (eggs or sperm) or in early embryonic development. These cases occur in people with no history of the disorder in their family.
