Genes affected

PLA2G2D (HGNC:9033): (phospholipase A2 group IID) This gene encodes a secreted member of the phospholipase A2 family, and is found in a cluster of related family members on chromosome 1. Phospholipase A2 family members hydrolyze the sn-2 fatty acid ester bond of glycerophospholipids to produce lysophospholipids and free fatty acid. This gene may be involved in inflammation and immune response, and in weight loss associated with chronic obstructive pulmonary disease. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Nov 2012]

Ambry Genetics

Dec 16, 2023

The c.145G>A (p.G49R) alteration is located in exon 2 (coding exon 2) of the PLA2G2D gene. This alteration results from a G to A substitution at nucleotide position 145, causing the glycine (G) at amino acid position 49 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
