Invitae RCV001057257 SCV001221740 uncertain significance Bardet-Biedl syndrome 2021-08-31 criteria provided, single submitter clinical testing This sequence change replaces aspartic acid with glycine at codon 490 of the BBS2 protein (p.Asp490Gly). The aspartic acid residue is moderately conserved and there is a moderate physicochemical difference between aspartic acid and glycine. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals affected with BBS2-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 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.
