RCV001290475 | SCV001478512 | likely pathogenic | Glanzmann thrombasthenia | 2023-10-17 | reviewed by expert panel | curation | The ITGA2B missense variant NM_000419.4:c.2468G>A replaces the glycine residue with a glutamic acid residue (p.Gly823Glu). This variant has been observed in a proband (PMID 25728920) with a phenotype specific for Glanzmann's thrombasthenia (PP4_strong) who also harbors a second ITGA2B variant (c.1413C>G, p.Tyr471Ter) previously classified by the VCEP as pathogenic (phase unconfirmed; PM3_supporting) . Furthermore, this variant has not been observed in population databases (absent from gnomAD v2.1.1 and v3; PM2_supporting) and the in silico meta-predictor REVEL score for this variant is 0.746 (above the VCEP-established threshold of 0.7; PP3). In summary, this variant is classified as likely pathogenic for autosomal recessive Glanzmann thrombasthenia. GT-specific criteria applied: PM2_supporting, PM3_supporting, PP3, and PP4_strong. |
