Genes affected

PTGER2 (HGNC:9594): (prostaglandin E receptor 2) This gene encodes a receptor for prostaglandin E2, a metabolite of arachidonic acid which has different biologic activities in a wide range of tissues. Mutations in this gene are associated with aspirin-induced susceptibility to asthma. [provided by RefSeq, Oct 2009]

The c.217G>A (p.E73K) alteration is located in exon 1 (coding exon 1) of the PTGER2 gene. This alteration results from a G to A substitution at nucleotide position 217, causing the glutamic acid (E) at amino acid position 73 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
