Labcorp Genetics (formerly Invitae), Labcorp RCV001240963 SCV001413951 uncertain significance Leukocyte adhesion deficiency 1 2022-04-30 criteria provided, single submitter clinical testing This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 593 of the ITGB2 protein (p.Arg593His). This variant is present in population databases (rs749255547, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with ITGB2-related conditions. ClinVar contains an entry for this variant (Variation ID: 966314). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive. This variant disrupts the p.Arg593 amino acid residue in ITGB2. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 1968911, 11703376, 12488604, 25514840). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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.
