RCV000811751 | SCV000952034 | pathogenic | Congenital myasthenic syndrome 4A | 2022-08-15 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals affected with CHRNE-related conditions. For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the CHRNE protein in which other variant(s) (p.Asn452Glufs*4) have been determined to be pathogenic (PMID: 8957026, 15951177, 19064877, 21175599, 28024842, 29054425). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. ClinVar contains an entry for this variant (Variation ID: 655554). This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Glu442Argfs*14) in the CHRNE gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 52 amino acid(s) of the CHRNE protein. |
