Description

This sequence change replaces valine, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 109 of the IFNAR2 protein (p.Val109Ala). This variant is present in population databases (rs369715958, gnomAD 0.2%). This variant has not been reported in the literature in individuals affected with IFNAR2-related conditions. ClinVar contains an entry for this variant (Variation ID: 1366629). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant¬†is likely to be tolerated. 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.
