It is caused by toxic RNA transcription from expanded CTG repeats in the 3'-untranslated region of DMPK , leading to dysregulated splicing of various genes and multisystemic symptoms. Often it causes weakness in the face, neck, arms and legs. Myotonic dystrophy (DM) is a multi-systemic inherited disease that affects at least 1 in 2,100 people or over 150,000 individuals in the US alone (Johnson 2021).

Both DM1 and DM2 affect several aspects of physical and mental functioning to varying degrees and with variable scope. A current disease model proposes that DM is caused by the expression of toxic microsatellite expansion RNAs that inhibit the RNA splicing function of the MBNL proteins resulting in the mis-expression . Myotonic dystrophy type 1 (DM1) is an inherited neuromuscular disease characterized by muscle rigidity, muscle weakness, and atrophy[1-3], with a prevalence of 0.5-18.1 per 100000 population.
