RCV000523228 | SCV000620343 | pathogenic | not provided | 2017-08-31 | criteria provided, single submitter | clinical testing | The W2010X nonsense variant in the VPS13B gene is predicted to cause loss of normal protein function either through protein truncation or nonsense-mediated mRNA decay. The W2010X variant is not observed in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). Although this pathogenic variant has not been reported previously to our knowledge, its presence is consistent with the diagnosis of Cohen syndrome. |

RCV001380881 | SCV001579066 | pathogenic | Cohen syndrome | 2020-09-15 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (ExAC no frequency). For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in VPS13B are known to be pathogenic (PMID: 15141358, 16648375, 20461111). This variant has not been reported in the literature in individuals with VPS13B-related conditions. ClinVar contains an entry for this variant (Variation ID: 451620). This sequence change creates a premature translational stop signal (p.Trp2010*) in the VPS13B gene. It is expected to result in an absent or disrupted protein product. |
