Genes affected

DGAT2 (HGNC:16940): (diacylglycerol O-acyltransferase 2) This gene encodes one of two enzymes which catalyzes the final reaction in the synthesis of triglycerides in which diacylglycerol is covalently bound to long chain fatty acyl-CoAs. The encoded protein catalyzes this reaction at low concentrations of magnesium chloride while the other enzyme has high activity at high concentrations of magnesium chloride. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Dec 2011]

The c.1139C>A (p.P380Q) alteration is located in exon 8 (coding exon 8) of the DGAT2 gene. This alteration results from a C to A substitution at nucleotide position 1139, causing the proline (P) at amino acid position 380 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
