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.

This variant, c.1841_1858del, results in the deletion of 6 amino acid(s) of the GP6 protein (p.Asn614_Leu619del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs774618165, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with GP6-related conditions. ClinVar contains an entry for this variant (Variation ID: 2066876). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
