The NM_000419.5(ITGA2B):c.2902del (p.Tyr968MetfsTer?) frameshift variant in exon 28 of 30 is predicted to alter the remaining 72 amino acids followed by a stop loss and the addition of 90 amino acids to the ITGA2B protein. This alters the transmembrane domain of the protein which is considered a critical region for protein function by the Platelet Disorders VCEP (PVS1_Strong). This variant is absent from gnomAD v2.1.1 (PM2_Supporting). It has been reported in at least one patient (GT14 in PMID: 25728920), whom displayed mucocutaneous bleeding and impaired aggregation with all agonists except ristocetin, which is highly specific for Glanzmann thrombasthenia. Additionally, αIIbβ3 surface expression was reduced to<5%, as measured by flow cytometry (PP4_strong). In summary this variant meets criteria to be classified as Pathogenic for autosomal recessive Glanzmann Thrombasthenia based on the ACMG/AMP criteria applied, as specified by the ClinGen PD VCEP: PVS1_strong, PP4_strong, PM2_supporting. (VCEP specifications version 2.1)
