RCV000410784 | SCV000920347 | pathogenic | Cohen syndrome | 2021-02-21 | criteria provided, single submitter | clinical testing | Variant summary: VPS13B c.436C>T (p.Arg146X) results in a premature termination codon, predicted to cause a truncation of the encoded protein or absence of the protein due to nonsense mediated decay, which are commonly known mechanisms for disease. At-least one truncation downstream of this position has been classified as pathogenic by our laboratory. The variant allele was found at a frequency of 2e-05 in 251172 control chromosomes. c.436C>T has been reported in the literature in at-least two individuals affected with Cohen Syndrome, one of whom as a critically ill infant, underwent extensive clinical and diagnostic workup by whole genome sequencing (example, El Chehadeh_2010, Duplomb_2019, Wang_2020). To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. Two clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. All submitters classified the variant as pathogenic/likely pathogenic citing overlapping evidence utilized in the context of this evaluation. Based on the evidence outlined above, the variant was classified as pathogenic. |
Invitae | RCV000410784 | SCV001391538 | pathogenic | Cohen syndrome | 2023-12-13 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Arg146*) in the VPS13B gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in VPS13B are known to be pathogenic (PMID: 15141358, 16648375, 20461111). This variant is present in population databases (rs144539572, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with Cohen syndrome (PMID: 20656880, 23188044). ClinVar contains an entry for this variant (Variation ID: 370440). For these reasons, this variant has been classified as Pathogenic. |
