Labcorp Genetics (formerly Invitae), Labcorp RCV001907738 SCV002129993 uncertain significance Cohen syndrome 2022-07-18 criteria provided, single submitter clinical testing This sequence change replaces lysine with glutamic acid at codon 617 of the VPS13B protein (p.Lys617Glu). The lysine residue is weakly conserved and there is a small physicochemical difference between lysine and glutamic acid. This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with VPS13B-related conditions. ClinVar contains an entry for this variant (Variation ID: 1364898). 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"). 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.
