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]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

The c.82A>G (p.S28G) alteration is located in exon 1 (coding exon 1) of the PTGER2 gene. This alteration results from a A to G substitution at nucleotide position 82, causing the serine (S) at amino acid position 28 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
