Genes affected
GP6 (HGNC:14388): (glycoprotein VI platelet) This gene encodes a platelet membrane glycoprotein of the immunoglobulin superfamily. The encoded protein is a receptor for collagen and plays a critical role in collagen-induced platelet aggregation and thrombus formation. The encoded protein forms a complex with the Fc receptor gamma-chain that initiates the platelet activation signaling cascade upon collagen binding. Mutations in this gene are a cause of platelet-type bleeding disorder-11 (BDPLT11). Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

GP6-AS1 (HGNC:55305): (GP6 antisense RNA 1)

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.1682G>C (p.R561T) alteration is located in exon 8 (coding exon 8) of the GP6 gene. This alteration results from a G to C substitution at nucleotide position 1682, causing the arginine (R) at amino acid position 561 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
