Genes affected

ITGB2 (HGNC:6155): (integrin subunit beta 2) This gene encodes an integrin beta chain, which combines with multiple different alpha chains to form different integrin heterodimers. Integrins are integral cell-surface proteins that participate in cell adhesion as well as cell-surface mediated signalling. The encoded protein plays an important role in immune response and defects in this gene cause leukocyte adhesion deficiency. Alternative splicing results in multiple transcript variants.

This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 201 of the ITGB2 protein (p.Pro201Leu). This variant is present in population databases (rs372179082, gnomAD 0.009%). 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: 567409). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on ITGB2 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. -
