Abstract

In a 3-year-old mentally retarded girl with homocystinuria due to 5,10-methylenetetrahydrofolate reductase deficiency among different therapeutic approaches only treatment with betaine (15–20 g/day) resulted in a satisfactory biochemical response. Betaine improved homocysteine remethylation and thus lowered plasma homocystine to trace amounts and normalized the previously very low plasma methionine concentration. This biochemical response was associated with a clinical improvement although she remained mentally retarded.
