Genes affected

MOGAT2 (HGNC:23248): (monoacylglycerol O-acyltransferase 2) The protein encoded by this gene is an enzyme that catalyzes the synthesis of diacylglycerol from 2-monoacylglycerol and fatty acyl-CoA. The encoded protein is important in the uptake of dietary fat by the small intestine. This protein forms a complex with diacylglycerol O-acyltransferase 2 in the endoplasmic reticulum, and this complex catalyzes the synthesis of triacylglycerol. [provided by RefSeq, Dec 2015]

Ambry Genetics

Dec 01, 2022

The c.649G>A (p.G217R) alteration is located in exon 4 (coding exon 4) of the MOGAT2 gene. This alteration results from a G to A substitution at nucleotide position 649, causing the glycine (G) at amino acid position 217 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
