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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2023The c.674T>G (p.I225S) alteration is located in exon 6 (coding exon 6) of the PLA1A gene. This alteration results from a T to G substitution at nucleotide position 674, causing the isoleucine (I) at amino acid position 225 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
