RCV002031666 | SCV002309217 | uncertain significance | Cohen syndrome | 2021-09-23 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamine with arginine at codon 1074 of the VPS13B protein (p.Gln1074Arg). The glutamine residue is moderately conserved and there is a small physicochemical difference between glutamine and arginine. 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: "Possibly Damaging"; 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 (ExAC no frequency). |
