Labcorp Genetics (formerly Invitae), Labcorp RCV002042934 SCV002301072 uncertain significance Intellectual disability, autosomal dominant 1 2021-02-14 criteria provided, single submitter clinical testing 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 (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be disruptive, but these predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with MBD5-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces threonine with arginine at codon 440 of the MBD5 protein (p.Thr440Arg). The threonine residue is highly conserved and there is a moderate physicochemical difference between threonine and arginine.
