Genes affected

PTGES (HGNC:9599): (prostaglandin E synthase) The protein encoded by this gene is a glutathione-dependent prostaglandin E synthase. The expression of this gene has been shown to be induced by proinflammatory cytokine interleukin 1 beta (IL1B). Its expression can also be induced by tumor suppressor protein TP53, and may be involved in TP53 induced apoptosis. Knockout studies in mice suggest that this gene may contribute to the pathogenesis of collagen-induced arthritis and mediate acute pain during inflammatory responses. [provided by RefSeq, Jul 2008]

May 30, 2024

The c.313G>A (p.V105I) alteration is located in exon 3 (coding exon 3) of the PTGES gene. This alteration results from a G to A substitution at nucleotide position 313, causing the valine (V) at amino acid position 105 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
