RCV000785964 | SCV000924547 | likely pathogenic | Cohen syndrome | 2018-06-15 | criteria provided, single submitter | research | The homozygous p.Phe3545ThrfsTer35 variant was identified by our study in an individual with Cohen syndrome. This variant has been identified in <0.01% (1/15010) of European (Non-Finnish) chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org). Although this variant has been seen in the general population, its frequency is low enough to be consistent with a recessive carrier frequency. Loss of function of the VPS13B gene is an established disease mechanism in autosomal recessive Cohen syndrome, and this is a loss of function variant. In summary, although additional studies are required to fully establish its pathogenicity, this variant is likely pathogenic. |

RCV000785964 | SCV001582158 | pathogenic | Cohen syndrome | 2020-10-26 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Phe3545Thrfs*35) 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 not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with VPS13B-related conditions. For these reasons, this variant has been classified as Pathogenic. |
