NCIt definition : Human CLCN1 wild-type allele is located in the vicinity of 7q34 and is approximately
36 kb in length. This allele, which encodes chloride channel protein 1, is involved
in voltage-dependent chloride transport in muscle cells. Mutation of the gene is associated
with autosomal recessive myotonia congenita (Becker disease), autosomal dominant myotonia
congenita (Thomsen disease) and a mild form of autosomal dominant myotonia, called
myotonia levior.;
NCIt note : Variations in the CLCN1 gene may also be associated with idiopathic generalized epilepsy.
