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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 02, 2024The c.113A>G (p.Y38C) alteration is located in exon 1 (coding exon 1) of the GPAT3 gene. This alteration results from a A to G substitution at nucleotide position 113, causing the tyrosine (Y) at amino acid position 38 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
