Riboflavin-responsive ethylmalonic-adipic aciduria

J Inherit Metab Dis. 1985;8(2):67-70. doi: 10.1007/BF01801667.


A patient presenting with a condition resembling Reye's syndrome was found to have a urinary organic acid excretion pattern similar to those previously described in a single patient with ethylmalonic-adipic aciduria. The present patient responded clinically to riboflavin supplementation and his fibroblasts, when cultured in riboflavin-depleted medium, showed an abnormal reduction in the rate of butyrate oxidation.
