Labcorp Genetics (formerly Invitae), Labcorp RCV003075703 SCV003468407 uncertain significance Glanzmann thrombasthenia 2024-01-25 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 909 of the ITGA2B protein (p.Val909Leu). This variant is present in population databases (rs573974230, gnomAD 0.08%). This variant has not been reported in the literature in individuals affected with ITGA2B-related conditions. ClinVar contains an entry for this variant (Variation ID: 2156901). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available". The leucine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
