Key result
Genetic analysis of the CLCN1 gene in 20 Italian patients identified five novel mutations that accounted for 10 of 22 recessive alleles, while no mutations were found in the dominant form.
Observational (n=20)
The study identifies novel CLCN1 mutations in Italian patients with recessive myotonia congenita, expanding the known genetic heterogeneity of the disease.

Expands CLCN1 spectrum in recessive myotonia congenita; leaves open need for functional validation and larger cohorts.
Sangiuolo et al. (1998) conducted an observational in Autosomal dominant and recessive myotonia congenita (n=20). CLCN1 gene mutations was evaluated on Identification of CLCN1 gene mutations. Genetic analysis of the CLCN1 gene in 20 Italian patients identified five novel mutations that accounted for 10 of 22 recessive alleles, while no mutations were found in the dominant form.
