Genes affected

DGAT1 (HGNC:2843): (diacylglycerol O-acyltransferase 1) This gene encodes an multipass transmembrane protein that functions as a key metabolic enzyme. The encoded protein catalyzes the conversion of diacylglycerol and fatty acyl CoA to triacylglycerol. This enzyme can also transfer acyl CoA to retinol. Activity of this protein may be associated with obesity and other metabolic diseases. [provided by RefSeq, Jul 2013]

This sequence change falls in intron 13 of the DGAT1 gene. It does not directly change the encoded amino acid sequence of the DGAT1 protein. This variant is present in population databases (rs782682584, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with DGAT1-related conditions. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant is not likely to affect RNA splicing. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
