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 GeneticsDec 18, 2023The c.598C>T (p.R200W) alteration is located in exon 5 (coding exon 5) of the GPAT3 gene. This alteration results from a C to T substitution at nucleotide position 598, causing the arginine (R) at amino acid position 200 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
