Genes affected

PLA2G5 (HGNC:9038): (phospholipase A2 group V) This gene is a member of the secretory phospholipase A2 family. It is located in a tightly-linked cluster of secretory phospholipase A2 genes on chromosome 1. The encoded enzyme catalyzes the hydrolysis of membrane phospholipids to generate lysophospholipids and free fatty acids including arachidonic acid. It preferentially hydrolyzes linoleoyl-containing phosphatidylcholine substrates. Secretion of this enzyme is thought to induce inflammatory responses in neighboring cells. Alternatively spliced transcript variants have been found, but their full-length nature has not been determined. [provided by RefSeq, Jul 2008]

PLA2G5 Gene-Disease associations (from GenCC):

• familial benign flecked retina

  Inheritance: AR Classification: DEFINITIVE, SUPPORTIVE, LIMITED Submitted by: G2P, Ambry Genetics, Orphanet
• late-adult onset retinitis pigmentosa

  Inheritance: AR Classification: LIMITED Submitted by: Franklin by Genoox

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.78).
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.612 is higher than 0.05.
