AbstractWe have studied six known heterozygotes for ornithine transcarbamylase (McKusick 31125; OTC) deficiency. All had abnormal results when tested by measurement of urine orotic acid after protein loading. Duodenal mucosa OTC assay detected fewer of the known heterozygotes but was a useful supplementary test. Urine orotic acid excretion after protein loading is influenced by age and results from women being tested must be compared with those from controls of appropriate age.
