Methylmalonic acidemia is an inborn error of organic acid metabolism resulting from defects in methylmalonyl CoA mutase. Analysis of plasma free amino acids in a 15-month-old Thai infant by HPLC showed marked elevation of glycine. HPLC analysis of urinary organic acids showed high levels of methylmalonic acid.
