Genes affected

MCAT (HGNC:29622): (malonyl-CoA-acyl carrier protein transacylase) The protein encoded by this gene is found exclusively in the mitochondrion, where it catalyzes the transfer of a malonyl group from malonyl-CoA to the mitochondrial acyl carrier protein. The encoded protein may be part of a fatty acid synthase complex that is more like the type II prokaryotic and plastid complexes rather than the type I human cytosolic complex. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Mar 2012]

The c.176C>T (p.P59L) alteration is located in exon 1 (coding exon 1) of the MCAT gene. This alteration results from a C to T substitution at nucleotide position 176, causing the proline (P) at amino acid position 59 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
