Genes affected

MLYCD (HGNC:7150): (malonyl-CoA decarboxylase) The product of this gene catalyzes the breakdown of malonyl-CoA to acetyl-CoA and carbon dioxide. Malonyl-CoA is an intermediate in fatty acid biosynthesis, and also inhibits the transport of fatty acyl CoAs into mitochondria. Consequently, the encoded protein acts to increase the rate of fatty acid oxidation. It is found in mitochondria, peroxisomes, and the cytoplasm. Mutations in this gene result in malonyl-CoA decarboyxlase deficiency. [provided by RefSeq, Jul 2008]

The c.13G>C (p.G5R) alteration is located in exon 1 (coding exon 1) of the MLYCD gene. This alteration results from a G to C substitution at nucleotide position 13, causing the glycine (G) at amino acid position 5 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
