Genes affected

PTGIR (HGNC:9602): (prostaglandin I2 receptor) The protein encoded by this gene is a member of the G-protein coupled receptor family 1 and has been shown to be a receptor for prostacyclin. Prostacyclin, the major product of cyclooxygenase in macrovascular endothelium, elicits a potent vasodilation and inhibition of platelet aggregation through binding to this receptor.

Collection Method: clinical testing

The c.917G>C (p.W306S) alteration is located in exon 3 (coding exon 2) of the PTGIR gene. This alteration results from a G to C substitution at nucleotide position 917, causing the tryptophan (W) at amino acid position 306 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
