WebSkeletal muscle chloride channelopathies, also known as myotonia congenita (MC), are subdivided based on their mode of inheritance: autosomal dominant or Thomsen myotonia congenita (TMC) 12 and autosomal recessive or Becker myotonia congenita (BMC). 13,14 Both TMC and BMC cause muscle stiffness that can be improved with repetitive … WebMyotonia can be inherited in an autosomal dominant or an autosomal recessive manner. Reduced penetrance, intra and inter-familial variability, and variable age-of-onset may be …
