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]

The c.292A>G (p.I98V) alteration is located in exon 3 (coding exon 3) of the PLA2G12A gene. This alteration results from a A to G substitution at nucleotide position 292, causing the isoleucine (I) at amino acid position 98 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
