[[http://www.uniprot.org/uniprot/OTC_HUMAN OTC_HUMAN]] Defects in OTC are the cause of ornithine carbamoyltransferase deficiency (OTCD) [MIM:[http://omim.org/entry/311250 311250]]. OTCD is an X-linked disorder of the urea cycle which causes a form of hyperammonemia. Mutations with no residual enzyme activity are always expressed in hemizygote males by a very severe neonatal hyperammonemic coma that generally proves to be fatal. Heterozygous females are either asymptomatic or express orotic aciduria spontaneously or after protein intake. The disorder is treatable with supplemental dietary arginine and low protein diet.
