A genetic congenital neuromuscular disorder affecting the skeletal muscles. It is caused by mutations in the chloride channel gene (clcn1 gene). It is characterized by muscle stiffness, hypertrophy, pain, and cramping
Congenital genetic disease characterized by tonic spasm and rigidity of certain muscles when a voluntary movement is attempted; also known as thomsen's disease
Inherited myotonic disorders with early childhood onset myotonia. Muscular hypertrophy is common and myotonia may impair ambulation and other movements. It is classified as thomsen (autosomal dominant) or becker (autosomal recessive) generalized myotonia mainly based on the inheritance pattern. Becker type is also clinically more severe. An autosomal dominant variant with milder symptoms and later onset is known as myotonia levior. Mutations in the voltage-dependent skeletal muscle chloride channel are associated with the disorders
