Labcorp Genetics (formerly Invitae), Labcorp RCV002007954 SCV002264302 uncertain significance Cohen syndrome 2022-03-19 criteria provided, single submitter clinical testing This sequence change replaces valine with isoleucine at codon 3944 of the VPS13B protein (p.Val3944Ile). The valine residue is weakly conserved and there is a small physicochemical difference between valine and isoleucine. 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: "Not Available"; PolyPhen-2: "Benign"; Align-GVGD: "Not Available"). This variant has not been reported in the literature in individuals affected with VPS13B-related conditions. This variant is not present in population databases (gnomAD no frequency).
