RCV003606688 | SCV004512152 | uncertain significance | Glanzmann thrombasthenia | 2023-09-17 | criteria provided, single submitter | clinical testing | 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. This missense change has been observed in individual(s) with clinical features of Glanzmann thrombasthenia (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is present in population databases (rs764819935, gnomAD 0.01%). This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 779 of the ITGA2B protein (p.Val779Ala). |
