Summaries for Homocystinuria Due to Cbs Deficiency

NIH Rare Diseases : 53 Homocystinuria due to CBS deficiency is an inherited disorder in which the body is unable to process certain building blocks of proteins (amino acids) properly. This form of homocystinuria is caused by the lack of an enzyme called cystathionine beta-synthase, which results from a mutation in the CBS gene. It is characterized by dislocation of the lens in the eye, an increased risk of abnormal blood clots, and skeletal abnormalities. Problems with development and learning are also evident in some cases. Homocystinuria due to CBS deficiency is inherited in an autosomal recessive pattern. Treatment aims to correct the biochemical abnormalities, especially to control blood homocystine concentration and prevent thrombosis (blood clots). Vitamin B6 (pyridoxine) therapy, protein-restricted and methionine-restricted diets, betaine treatment, and/or folate and vitamin B12 supplementation may be used to manage the condition.

MalaCards based summary : Homocystinuria Due to Cbs Deficiency, also known as homocystinuria due to cystathionine beta-synthase deficiency, is related to homocystinuria caused by cystathionine beta-synthase deficiency and homocystinuria due to cystathionine beta-synthase deficiency, and has symptoms including seizures An important gene associated with Homocystinuria Due to Cbs Deficiency is CBS (Cystathionine-Beta-Synthase). The drug Taurine has been mentioned in the context of this disorder. Affiliated tissues include eye, monocytes and liver.
