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.

The c.1265G>A (p.R422Q) alteration is located in exon 15 (coding exon 14) of the PLA2G4C gene. This alteration results from a G to A substitution at nucleotide position 1265, causing the arginine (R) at amino acid position 422 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
