RESUMO

Seven infants in one kindred died: one was stillborn; the others, who were floppy at birth and were breast-fed, developed a disorder with the odor of sweaty feet and died in early infancy. In two further pregnancies, 3-hydroxvisovaleric, glutaric, and C6-C10-dicarboxylic acids were demonstrated in the mother's urine during the seventh month. Riboflavin therapy in the last trimester of pregnancy and a riboflavin-rich diet given the infants prevented this syndrome. The presence of abnormal erythrocyte glutathione-reductase activity in the mother while she excreted normal amounts of riboflavin in her urine indicates a probable disorder of riboflavin metabolism resulting in multiple acyl-CoA dehydrogenase deficiency.
