WebNational Center for Biotechnology Information WebDec 21, 2024 · The homocysteine blood test measures the amount of homocysteine in your body. Typically, this test is used to diagnose a vitamin B6, B9, B12, or folic acid deficiency. A lack of these important vitamins increases homocysteine and can put you at a higher risk of cardiovascular disease.
WebStrategies for the treatment of cystathionine β-synthase (CBS) deficiency include (1) increasing residual enzyme activity by giving pyridoxine in those patients with vitamin responsive variants, (2) reducing the load on the affected pathway with a low methionine diet and supplementing the diet with cysteine; and (3) giving betaine in order to utilise … WebMutations in the CBS, MTHFR, MTR, MTRR, and MMADHC genes cause homocystinuria..
