Description

ClinVar contains an entry for this variant (Variation ID: 64391). This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 100 of the KCNJ1 protein (p.Tyr100Cys). This variant is present in population databases (rs387907439, gnomAD 0.002%). This variant has not been reported in the literature in individuals affected with KCNJ1-related conditions. 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. 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.
