Genes affected

PLA2G7 (HGNC:9040): (phospholipase A2 group VII) The protein encoded by this gene is a secreted enzyme that catalyzes the degradation of platelet-activating factor to biologically inactive products. Defects in this gene are a cause of platelet-activating factor acetylhydrolase deficiency. Two transcript variants encoding the same protein have been found for this gene.[provided by RefSeq, Dec 2009]

The c.875G>T (p.G292V) alteration is located in exon 10 (coding exon 9) of the PLA2G7 gene. This alteration results from a G to T substitution at nucleotide position 875, causing the glycine (G) at amino acid position 292 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
