RCV001361578 | SCV001557556 | uncertain significance | Familial aplasia of the vermis; Meckel-Gruber syndrome | 2022-02-04 | criteria provided, single submitter | clinical testing | This sequence change replaces isoleucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 967 of the CC2D2A protein (p.Ile967Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with CC2D2A-related conditions. ClinVar contains an entry for this variant (Variation ID: 1053256). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. |
