WebBackground & aims: Cystathionine beta-synthase (CBS) deficiency causes severe hyperhomocysteinemia, which confers diverse clinical manifestations, notably liver disease. To investigate this aspect of hyperhomocysteinemia, we performed a thorough investigation of liver pathology in CBS-deficient mice, a murine model of severe hyperhomocysteinemia. WebCystathionine beta-synthase, along with vitamin B 6, converts homocysteine to cystathionine (see Fig. 5-8). A deficiency of this enzyme leads to accumulation not only of homocysteine but also its precursor, methionine. The genetic disorder, homocystinuria, is attributable to a mutation on chromosome 21. WebCystathionine β-synthase is a pyridoxine (vitamin B6)-dependent enzyme. Rare disorders that also lead to homocystinuria include defects in folate or cobalamin metabolism. Screening programs for homocystinuria are based on detection of elevated blood levels of methionine, a precursor of cystathionine. in a haphazard manner crossword
