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]

Ambry Genetics

Feb 13, 2024

The c.423C>G (p.H141Q) alteration is located in exon 3 (coding exon 3) of the MOGAT1 gene. This alteration results from a C to G substitution at nucleotide position 423, causing the histidine (H) at amino acid position 141 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
