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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 13, 2021The c.163C>T (p.L55F) alteration is located in exon 2 (coding exon 2) of the PLA1A gene. This alteration results from a C to T substitution at nucleotide position 163, causing the leucine (L) at amino acid position 55 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
