Genes affected

AGPAT3 (HGNC:326): (1-acylglycerol-3-phosphate O-acyltransferase 3) The protein encoded by this gene is an acyltransferase that converts lysophosphatidic acid into phosphatidic acid, which is the second step in the de novo phospholipid biosynthetic pathway. The encoded protein may be an integral membrane protein. Two transcript variants encoding the same protein have been found for this gene. [provided by RefSeq, Jul 2008]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.455G>A (p.R152Q) alteration is located in exon 5 (coding exon 3) of the AGPAT3 gene. This alteration results from a G to A substitution at nucleotide position 455, causing the arginine (R) at amino acid position 152 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
