Abstract
Three infants with malonic aciduria are reported, one of whom could be studied in detail. All children had severe and progressive encephalopathy with intermittent ketoacidosis and hypoglycemia. One infant died of cardiomyopathy. Biochemical studies revealed that one patient had neither malonyl-CoA decarboxylase nor glutaryl-CoA dehydrogenase deficiencies. This variant of malonic aciduria is different from that of four patients previously reported, both in its clinical and biochemical presentations. The biochemical pathology of this variant malonic aciduria is unknown.
