RCV000558574 | SCV000630882 | uncertain significance | Cohen syndrome | 2022-08-19 | criteria provided, single submitter | clinical testing | This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 2258 of the VPS13B protein (p.Leu2258Arg). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Cohen syndrome (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. ClinVar contains an entry for this variant (Variation ID: 459248). 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"). 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. |
