Abstract excerpt
Myotonia congenita is a genetic disease characterized by impaired muscle relaxation after forceful contraction (myotonia) and caused by mutations in the chloride channel voltage-sensitive 1 (CLCN1) gene, encoding the voltage-gated chloride channel of skeletal muscle (ClC-1). In a large cohort of clinically diagnosed unrelated probands, we identified 75 different CLCN1 mutations in 106 individuals, among which 29...
