RCV001942656 | SCV002130530 | uncertain significance | Cohen syndrome | 2022-02-15 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD no frequency). 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 output the following: SIFT: "Not Available"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Not Available". The proline amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with VPS13B-related conditions. This sequence change replaces leucine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 1900 of the VPS13B protein (p.Leu1900Pro). |
