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 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.0863823).

The c.728G>T (p.G243V) alteration is located in exon 1 (coding exon 1) of the PTGER2 gene. This alteration results from a G to T substitution at nucleotide position 728, causing the glycine (G) at amino acid position 243 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
