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]

The c.804T>A (p.H268Q) alteration is located in exon 7 (coding exon 7) of the GPAT3 gene. This alteration results from a T to A substitution at nucleotide position 804, causing the histidine (H) at amino acid position 268 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
