Labcorp Genetics (formerly Invitae), Labcorp RCV003606730 SCV004517554 uncertain significance Glanzmann thrombasthenia 2023-11-28 criteria provided, single submitter clinical testing This sequence change replaces glutamine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 49 of the ITGA2B protein (p.Gln49Leu). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with ITGA2B-related conditions. 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 with a negative predictive value of 80%. 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.
