Homocystinuria - Prevention

Alternative Names

Cystathionine beta synthase deficiency

Prevention:

Genetic counseling is recommended for prospective parents with a family history of homocystinuria. Intrauterine diagnosis of homocystinuria is available. This involves culturing amniotic cells or chorionic villi to test for cystathionine synthase (the enzyme that is missing in homocystinuria).
