Genes affected

PTGER4 (HGNC:9596): (prostaglandin E receptor 4) The protein encoded by this gene is a member of the G-protein coupled receptor family. This protein is one of four receptors identified for prostaglandin E2 (PGE2). This receptor can activate T-cell factor signaling. It has been shown to mediate PGE2 induced expression of early growth response 1 (EGR1), regulate the level and stability of cyclooxygenase-2 mRNA, and lead to the phosphorylation of glycogen synthase kinase-3. Knockout studies in mice suggest that this receptor may be involved in the neonatal adaptation of circulatory system, osteoporosis, as well as initiation of skin immune responses.

The c.1337A>G (p.Q446R) alteration is located in exon 3 (coding exon 2) of the PTGER4 gene. This alteration results from a A to G substitution at nucleotide position 1337, causing the glutamine (Q) at amino acid position 446 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
