Fatal hyperammonemia resulting from a C-to-T mutation at a MspI site of the ornithine transcarbamylase gene.

Human genetics - 1 Dec 1991

Abstract excerpt

Ornithine transcarbamylase (OTC) deficiency is the most common inborn error of the urea cycle in humans and is responsible for lethal neonatal hyperammonemia in males. Partial OTC deficiency also occurs in females and can be responsible for life-threatening hyperammonemic comas in heterozygotes. The cosegregation of the trait with a 5.8-kb abnormal MspI fragment in an affected family led us to hypothesize that...
