WebMyotonia congenita is characterized by muscle stiffness present from childhood; all striated muscle groups including the extrinsic eye muscles, facial muscles, and tongue may be involved. Stiffness is relieved by repeated contractions of the muscle (the "warm-up" phenomenon). Muscles are usually hypertrophic. WebMolecular Genetic Testing Used in Myotonia Congenita 1. See Table A. Genes and Databases for chromosome locus and protein. 2. See Molecular Genetics for information on variants detected in this gene. 3. Sequence analysis detects variants that are benign, likely benign, of uncertain significance, likely pathogenic, or pathogenic.
