Labcorp Genetics (formerly Invitae), Labcorp RCV001921543 SCV002203387 pathogenic Myasthenic syndrome, congenital, 22 2020-11-30 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site, but this prediction has not been confirmed by published transcriptional studies. This variant has not been reported in the literature in individuals with PREPL-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Arg510*) in the PREPL gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in PREPL are known to be pathogenic (PMID: 24610330, 28726805, 29913539).
