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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 09, 2024The c.893T>C (p.V298A) alteration is located in exon 2 (coding exon 1) of the PTGDR2 gene. This alteration results from a T to C substitution at nucleotide position 893, causing the valine (V) at amino acid position 298 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
