Description

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 tolerated, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. 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. This variant has not been reported in the literature in individuals with GJB6-related disease. This sequence change replaces glutamic acid with glutamine at codon 101 of the GJB6 protein (p.Glu101Gln). The glutamic acid residue is moderately conserved and there is a small physicochemical difference between glutamic acid and glutamine. This variant is present in population databases (rs571454176, ExAC 0.02%).
