Genes affected

GPAT3 (HGNC:28157): (glycerol-3-phosphate acyltransferase 3) This gene encodes a member of the lysophosphatidic acid acyltransferase protein family. The encoded protein is an enzyme which catalyzes the conversion of glycerol-3-phosphate to lysophosphatidic acid in the synthesis of triacylglycerol. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Jan 2012]

Ambry Genetics

Jan 05, 2022

The c.1214G>A (p.G405E) alteration is located in exon 12 (coding exon 12) of the GPAT3 gene. This alteration results from a G to A substitution at nucleotide position 1214, causing the glycine (G) at amino acid position 405 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
