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 GeneticsMar 18, 2024The c.985G>A (p.V329I) alteration is located in exon 9 (coding exon 9) of the GPAT3 gene. This alteration results from a G to A substitution at nucleotide position 985, causing the valine (V) at amino acid position 329 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
