Genes affected

MOGAT1 (HGNC:18210): (monoacylglycerol O-acyltransferase 1) Acyl-CoA:monoacylglycerol acyltransferase (MOGAT; EC 2.3.1.22) catalyzes the synthesis of diacylglycerols, the precursor of physiologically important lipids such as triacylglycerol and phospholipids (Yen et al., 2002 [PubMed 12077311]).[supplied by OMIM, Mar 2008]

Nov 03, 2022

The c.651T>A (p.H217Q) alteration is located in exon 4 (coding exon 4) of the MOGAT1 gene. This alteration results from a T to A substitution at nucleotide position 651, causing the histidine (H) at amino acid position 217 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
