| Definitions |
[CSP Definition]: Autosomal recessive inborn error of methionine metabolism usually caused by a deficiency of cystathionine beta-synthase and associated with elevations of homocysteine in plasma and urine; clinical features include a tall, slender habitus, scoliosis, arachnodactyly, muscle weakness, genu varis, thin blond hair, malar flush, lens dislocations, an increased incidence of mental retardation, and a tendency to develop fibrosis of arteries, frequently complicated by cerebrovascular accidents and myocardial infarction. [HPO Definition]: An increased concentration of homocystine in the urine. [HPO:gcarletti] [NCIt Definition]: An autosomal recessive inherited metabolic disorder caused by mutations in the CBS, MTHFR, MTR, and MTRR genes. It is characterized by abnormalities in the methionine metabolism and is associated with deficiency of cystathionine synthase. It results in the accumulation of homocysteine in the serum. It may affect the cardiovascular, musculoskeletal and the central nervous systems. [MSH Definition]: Autosomal recessive inborn error of methionine metabolism usually caused by a deficiency of CYSTATHIONINE BETA-SYNTHASE and associated with elevations of homocysteine in plasma and urine. Clinical features include a tall slender habitus, SCOLIOSIS, arachnodactyly, MUSCLE WEAKNESS, genu varus, thin blond hair, malar flush, lens dislocations, an increased incidence of MENTAL RETARDATION, and a tendency to develop fibrosis of arteries, frequently complicated by CEREBROVASCULAR ACCIDENTS and MYOCARDIAL INFARCTION. (From Adams et al., Principles of Neurology, 6th ed, p979) [GARD Definition]: Homocystinuria is an inherited disorder in which the body is unable to process certain building blocks of proteins (amino acids) properly. The most common form, called cystathionine beta-synthase deficiency, is characterized by dislocation of the lens in the eye, an increased risk of abnormal blood clots, skeletal abnormalities, and sometimes problems with development and learning. Less common forms are caused by a lack of other enzymes. These disorders can cause intellectual disability, seizures, problems with movement, and a blood disorder called megaloblastic anemia. Mutations in the CBS, MTHFR, MTR, and MTRR genes cause homocystinuria, and it is inherited in an autosomal recessive manner. Treatment varies depending upon the cause of the disorder. - this information is from GARD/ORDR/NCATS. |
