GeneDx RCV000188075 SCV000241679 likely benign not specified 2017-07-06 criteria provided, single submitter clinical testing This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.
Invitae RCV000694398 SCV000822842 uncertain significance Mental retardation, autosomal dominant 1 2018-12-21 criteria provided, single submitter clinical testing This sequence change replaces methionine with valine at codon 321 of the MBD5 protein (p.Met321Val). The methionine residue is highly conserved and there is a small physicochemical difference between methionine and valine. This variant is present in population databases (rs369869865, ExAC 0.006%). This variant has not been reported in the literature in individuals with MBD5-related disease. ClinVar contains an entry for this variant (Variation ID: 206065). Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C15"). 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.
