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 GeneticsJun 07, 2024The c.373G>A (p.D125N) 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 373, causing the aspartic acid (D) at amino acid position 125 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
