Genes affected

HPGDS (HGNC:17890): (hematopoietic prostaglandin D synthase) Prostaglandin-D synthase is a sigma class glutathione-S-transferase family member. The enzyme catalyzes the conversion of PGH2 to PGD2 and plays a role in the production of prostanoids in the immune system and mast cells. The presence of this enzyme can be used to identify the differentiation stage of human megakaryocytes. [provided by RefSeq, Jul 2008]

The c.109G>A (p.A37T) alteration is located in exon 2 (coding exon 1) of the HPGDS gene. This alteration results from a G to A substitution at nucleotide position 109, causing the alanine (A) at amino acid position 37 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
