Labcorp Genetics (formerly Invitae), Labcorp RCV003037923 SCV003318668 pathogenic Congenital myasthenic syndrome 4A 2022-03-11 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant has not been reported in the literature in individuals affected with CHRNE-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Asp223Thrfs*82) in the CHRNE gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in CHRNE are known to be pathogenic (PMID: 22678886).
