Also known as GPIX; CD42a

Gene ID: 2815 | Gene type: protein coding

About GP9

Cytogenetic location: 3q21.3 Genomic coordinates (GRCh38): 3:129,054,845-129,062,406 (from NCBI)

This gene has 1 transcript (splice variant), 160 orthologues, 1 paralogue and is associated with 2 phenotypes. Biased expression in bone marrow (RPKM 1.0), spleen (RPKM 0.7) and 4 other tissues.

Summary

This gene encodes a small membrane glycoprotein found on the surface of human platelets. It forms a 1-to-1 noncovalent complex with glycoprotein Ib, a platelet surface membrane glycoprotein complex that functions as a receptor for von Willebrand factor. The complete receptor complex includes noncovalent association of the alpha and beta subunits with the protein encoded by this gene and platelet glycoprotein V. Defects in this gene are a cause of Bernard-Soulier syndrome, also known as giant platelet disease. These patients have unusually large platelets and have a clinical bleeding tendency.
