ClinGen Platelet Disorders Variant Curation Expert Panel, ClinGen RCV000852093 SCV001809863 uncertain significance Glanzmann thrombasthenia 2024-06-06 reviewed by expert panel curation The NM_000419.5(ITGA2B):c.2569T>C (p.Cys857Arg) missense variant is predicted deleterious with a REVEL score of 0.741 (PP3). The highest population minor allele frequency in gnomAD v4.0 is 0.000007875 (6/761904 alleles) in the European (non-Finnish) population, which is lower than the ClinGen PD VCEP threshold (<0.0001; PM2_Supporting). It reported in one patient stated to have a disease of platelet function (PMID: 31064749) but information was insufficient or inconsistent to apply any evidence for this patient. Cys857Arg occurs at the same amino acid residue as Cys857Phe which is also classified by the PD-VCEP as VUS. In summary, based on the evidence available at this time, the variant is classified as uncertain significance. GT-specific criteria applied: PM2_supporting and PP3.
