Myotonia congenita, Thomsen type, first described in 1876, is an autosomal dominant condition with a prevalence of about 1 : 400,000. WebMyotonia congenita is caused by pathogenic variants in CLCN1 (Abdalla et al. 1992). The CLCN1 gene encodes the voltage-gated chloride channel ClC-1, which is highly expressed in the sarcolemma in skeletal muscle. The main function of ClC-1 is to regulate cellular excitability and to stabilize the resting potential (Pedersen et al. 2016). slow sky broadband in my area
