Description

This sequence change replaces isoleucine, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 39 of the BBS4 protein (p.Ile39Thr). 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C45"). This variant has not been reported in the literature in individuals affected with BBS4-related conditions. This variant is not present in population databases (gnomAD no frequency).
