Genes affected

PACERR (HGNC:50552): (PTGS2 antisense NFKB1 complex-mediated expression regulator RNA) This gene represents transcription of a long non-coding RNA produced in antisense to the prostaglandin-endoperoxide synthase 2 (PTGS2) gene. This transcript interacts with NF-kB transcriptional regulators to promote expression of PTGS2. [provided by RefSeq, Feb 2015]

PTGS2 (HGNC:9605): (prostaglandin-endoperoxide synthase 2) Prostaglandin-endoperoxide synthase (PTGS), also known as cyclooxygenase, is the key enzyme in prostaglandin biosynthesis, and acts both as a dioxygenase and as a peroxidase. There are two isozymes of PTGS: a constitutive PTGS1 and an inducible PTGS2, which differ in their regulation of expression and tissue distribution. This gene encodes the inducible isozyme. It is regulated by specific stimulatory events, suggesting that it is responsible for the prostanoid biosynthesis involved in inflammation and mitogenesis. [provided by RefSeq, Feb 2009]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0801 is higher than 0.05.
