Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Nov 26, 2022 | For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with CWC27-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Ile41Tyrfs*10) in the CWC27 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CWC27 are known to be pathogenic (PMID: 28285769). - |
