Dietary treatment of homocystinuria.

Abstract
Homocystinuric patients fed normal diets accumulate methionine in their body fluids and tissues. There is also an abnormal amount of circulating homocystine and a lack of cystathionine in certain tissues. Proper, inexpensive therapy might be to reduce the methionine intake to minimal requirements and supplement the diet with cystine. This was tried on a homocystinuric infant. Presently the 2-year old girl''s mental and physical development are normal (except for a tendency to show genu valgum). She has no more manifestations of homocystinuria.
