Ornithine carbamoyltransferase deficiency

OTC deficiency is an x-linked recessive metabolic disorder of the urea cycle characterized by hyperammonemia. The disease is manageable by dietary arginine and low protein diet.

Epidemiology

OTC deficiency is the most common urea cycle disorder. Its prevalence is about 1/40,000.[Error: Macro 'ref' doesn't exist]
