ClinGen Platelet Disorders Variant Curation Expert Panel, ClinGen RCV001225284 SCV001397561 pathogenic Glanzmann thrombasthenia 2023-11-02 reviewed by expert panel curation The NM_000212.2:c.628T>A (p.Cys210Ser) missense variant has been reported in the compound heterozygous state (in trans with Pathogenic variant Pro189Ser) in one proband and his brother (PMID: 31565851) with a phenotype highly specific to GT (PM3, PP4_moderate). Multiple lines of computational evidence support a deleterious effect with a REVEL score of 0.963 (PP3). The variant is absent from population databases, including gnomADv2.1.1 (PM2_supporting). Functional studies show reduced binding to fibrinogen when expressed in CHO cells (PMID: 14690453; PS3). In summary this variant meets criteria to be classified as Pathogenic for autosomal recessive Glanzmann thrombasthenia. GT-specific criteria applied: PP4_moderate, PP3, PP1, PM2_supporting, PM3, PS3.
