Genes affected

PLA2G6 (HGNC:9039): (phospholipase A2 group VI) The protein encoded by this gene is an A2 phospholipase, a class of enzyme that catalyzes the release of fatty acids from phospholipids. The encoded protein may play a role in phospholipid remodelling, arachidonic acid release, leukotriene and prostaglandin synthesis, fas-mediated apoptosis, and transmembrane ion flux in glucose-stimulated B-cells. Several transcript variants encoding multiple isoforms have been described, but the full-length nature of only three of them have been determined to date. [provided by RefSeq, Dec 2010]

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The E501K variant in the PLA2G6 gene has not been reported previously as a pathogenic variantnor as a benign polymorphism, to our knowledge. The E501K variant was not observed in approximately6400 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project,indicating it is not a common benign variant in these populations. The E501K variant is a non-conservativeamino acid substitution, which occurs at a position that is conserved across species, and in silico analysispredicts this variant is probably damaging to the protein structure/function. In addition, a differentmissense variant at this residue (E501Q) as well as missense variants at nearby residues (L491R,A499V, K502N) have been reported in the Human Gene Mutation Database in association with PLA2G6-related disorders (Stenson et al., 2014), supporting the functional importance of this region of the protein. We interpret E501K as a pathogenic variant. -
