Genes affected
PLA2G12A (HGNC:18554): (phospholipase A2 group XIIA) Secreted phospholipase A2 (sPLA2) enzymes liberate arachidonic acid from phospholipids for production of eicosanoids and exert a variety of physiologic and pathologic effects. Group XII sPLA2s, such as PLA2G12A, have relatively low specific activity and are structurally and functionally distinct from other sPLA2s (Gelb et al., 2000 [PubMed 11031251]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 22, 2024The c.320G>A (p.C107Y) alteration is located in exon 3 (coding exon 3) of the PLA2G12A gene. This alteration results from a G to A substitution at nucleotide position 320, causing the cysteine (C) at amino acid position 107 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
