Genes affected

PLA1A (HGNC:17661): (phospholipase A1 member A) The protein encoded by this gene is a phospholipase that hydrolyzes fatty acids at the sn-1 position of phosphatidylserine and 1-acyl-2-lysophosphatidylserine. This secreted protein hydrolyzes phosphatidylserine in liposomes. Three transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, May 2011]

The c.307A>G (p.T103A) alteration is located in exon 3 (coding exon 3) of the PLA1A gene. This alteration results from a A to G substitution at nucleotide position 307, causing the threonine (T) at amino acid position 103 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
