NCIt definition : Human CPOX wild-type allele is located in the vicinity of 3q11.2 and is approximately
23 kb in length. This allele, which encodes oxygen-dependent coproporphyrinogen-III
oxidase, mitochondrial protein, plays a role in the biosynthesis of heme via production
of protoporphyrinogen-IX. Mutations in the gene are associated with coproporphyria
and harderoporphyria.;
