Labcorp Genetics (formerly Invitae), Labcorp RCV002592290 SCV003500209 uncertain significance Glanzmann thrombasthenia 2023-04-17 criteria provided, single submitter clinical testing This variant is present in population databases (no rsID available, gnomAD 0.009%). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt ITGA2B protein function. ClinVar contains an entry for this variant (Variation ID: 2182972). This variant has not been reported in the literature in individuals affected with ITGA2B-related conditions. This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 923 of the ITGA2B protein (p.Leu923Val).
