OTC - ornithine transcarbamylase Gene
Also Known as OCTD; OTC1; OTCD; OTCase
Species: Homo sapiens
About OTC
This gene has 3 transcripts (splice variants), 201 orthologues, 2 paralogues and is associated with 3 phenotypes. Biased expression in liver (RPKM 75.1), duodenum (RPKM 47.8) and 1 other tissue.
Summary
This nuclear gene encodes a mitochondrial matrix enzyme. The encoded protein is involved in the urea cycle which functions to detoxify ammonia into urea for excretion. Mutations in this enzyme lead to ornithine transcarbamylase deficiency, which causes hyperammonemia. [provided by RefSeq, May 2022]
