Genes affected

PTGDR2 (HGNC:4502): (prostaglandin D2 receptor 2) This gene encodes a G-protein-coupled receptor that is preferentially expressed in CD4+ effector T helper 2 (Th2) cells. This protein is a prostaglandin D2 receptor that mediates the pro-inflammatory chemotaxis of eosinophils, basophils, and Th2 lymphocytes generated during allergic inflammation. Single nucleotide polymorphisms in the 3' UTR of this gene have been associated with asthma susceptibility.[provided by RefSeq, Mar 2011]

The c.765C>A (p.F255L) alteration is located in exon 2 (coding exon 1) of the PTGDR2 gene. This alteration results from a C to A substitution at nucleotide position 765, causing the phenylalanine (F) at amino acid position 255 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
