Genes affected

PLA2G4C (HGNC:9037): (phospholipase A2 group IVC) This gene encodes a protein which is a member of the phospholipase A2 enzyme family which hydrolyzes glycerophospholipids to produce free fatty acids and lysophospholipids, both of which serve as precursors in the production of signaling molecules. The encoded protein has been shown to be a calcium-independent and membrane bound enzyme. Multiple transcript variants encoding different isoforms have been found for this gene.

ACMG classification

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

• BP4: Computational evidence support a benign effect (MetaRNN=1.5327334E-4).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.488 is higher than 0.05.
