ClinGen Platelet Disorders Variant Curation Expert Panel, ClinGen RCV001290455 SCV001478489 uncertain significance Glanzmann thrombasthenia 2023-09-07 reviewed by expert panel curation The NM_000419.4:c.2602-3C>A is a splice region variant in intron 25. The variant occurs at a very low frequency in population databases, with 0.00003830 (1/26801 alleles) in the gnomADv2.1.1 Latino/Admixed American population (PM2_supporting). It is reported in one compound heterozygous individual with the c.2602-2A>G and Thr281Ile (PMID: 25373348). GT16 of PMID: 25373348 meets bleeding phenotype, aggregometry criteria, integrin expression is reported to be <5% reduced by flow cytometry, and all exons of ITGA2B and ITGB3 genes as well as surrounding intron regions were sequenced (PP4_strong). In summary, there is insufficient evidence at this time to classify this variant for autosomal recessive Glanzmann thrombasthenia. GT-specific criteria applied: PM2_Supporting, PP4_Strong.
