Genes affected

PTGS1 (HGNC:9604): (prostaglandin-endoperoxide synthase 1) This is one of two genes encoding similar enzymes that catalyze the conversion of arachidonate to prostaglandin. The encoded protein regulates angiogenesis in endothelial cells, and is inhibited by nonsteroidal anti-inflammatory drugs such as aspirin. Based on its ability to function as both a cyclooxygenase and as a peroxidase, the encoded protein has been identified as a moonlighting protein. The protein may promote cell proliferation during tumor progression. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2021]

Aug 30, 2022

The c.730C>T (p.R244W) alteration is located in exon 7 (coding exon 7) of the PTGS1 gene. This alteration results from a C to T substitution at nucleotide position 730, causing the arginine (R) at amino acid position 244 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
