Summary

MCEE (methylmalonyl-CoA epimerase, HGNC:16732) is a protein-coding gene on chromosome 2p13.3, encoding Methylmalonyl-CoA epimerase, mitochondrial (Q96PE7). Methylmalonyl-CoA epimerase involved in propionyl-CoA metabolism.

The product of this gene catalyzes the interconversion of D- and L-methylmalonyl-CoA during the degradation of branched chain amino acids. odd chain-length fatty acids, and other metabolites. Mutations in this gene result in methylmalonyl-CoA epimerase deficiency, which is presented as mild to moderate methylmalonic aciduria.
