Genes affected

MCEE (HGNC:16732): (methylmalonyl-CoA epimerase) 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. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.469C>T (p.P157S) alteration is located in exon 3 (coding exon 3) of the MCEE gene. This alteration results from a C to T substitution at nucleotide position 469, causing the proline (P) at amino acid position 157 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
