RCV002046548 | SCV002308183 | likely pathogenic | Familial aplasia of the vermis; Meckel-Gruber syndrome | 2022-11-29 | criteria provided, single submitter | clinical testing | In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 1104 of the CC2D2A protein (p.Glu1104Lys). This variant disrupts the p.Glu1104 amino acid residue in CC2D2A. Other variant(s) that disrupt this residue have been determined to be pathogenic (Invitae). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site. Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. ClinVar contains an entry for this variant (Variation ID: 1522405). This variant has not been reported in the literature in individuals affected with CC2D2A-related conditions. This variant is not present in population databases (gnomAD no frequency). |
