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]

Ambry Genetics

Apr 26, 2023

The c.356T>C (p.L119P) alteration is located in exon 5 (coding exon 4) of the HPGDS gene. This alteration results from a T to C substitution at nucleotide position 356, causing the leucine (L) at amino acid position 119 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
