Genes affected

PTGR2 (HGNC:20149): (prostaglandin reductase 2) This gene encodes an enzyme involved in the metabolism of prostaglandins. The encoded protein catalyzes the NADPH-dependent conversion of 15-keto-prostaglandin E2 to 15-keto-13,14-dihydro-prostaglandin E2. This protein may also be involved in regulating activation of the peroxisome proliferator-activated receptor. Alternative splicing results in multiple transcript variants.

The c.280G>A (p.D94N) alteration is located in exon 4 (coding exon 3) of the PTGR2 gene. This alteration results from a G to A substitution at nucleotide position 280, causing the aspartic acid (D) at amino acid position 94 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
