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.1153A>G (p.N385D) 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 1153, causing the asparagine (N) at amino acid position 385 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
