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]

Ambry Genetics

Feb 13, 2024

The c.1067A>G (p.D356G) alteration is located in exon 11 (coding exon 10) of the PLA2G7 gene. This alteration results from a A to G substitution at nucleotide position 1067, causing the aspartic acid (D) at amino acid position 356 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
