RCV000821704 | SCV000962473 | uncertain significance | Cohen syndrome | 2018-10-07 | criteria provided, single submitter | clinical testing | 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: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C0"). This variant has not been reported in the literature in individuals with VPS13B-related disease. This variant is present in population databases (rs376044341, ExAC 0.001%). This sequence change replaces serine with phenylalanine at codon 870 of the VPS13B protein (p.Ser870Phe). The serine residue is moderately conserved and there is a large physicochemical difference between serine and phenylalanine. 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. |
