Labcorp Genetics (formerly Invitae), Labcorp RCV001221403 SCV001393447 pathogenic Congenital myotonia, autosomal recessive form; Congenital myotonia, autosomal dominant form 2019-10-07 criteria provided, single submitter clinical testing This sequence change creates a premature translational stop signal (p.Leu159Cysfs*11) in the CLCN1 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been observed in an individual affected with autosomal recessive myotonia congenita (PMID: 29480456). Loss-of-function variants in CLCN1 are known to be pathogenic (PMID: 17932099, 22094069, 23739125). For these reasons, this variant has been classified as Pathogenic.
