Dystrophies are chronic genetically determined diseases, clinically manifested by muscular and non-muscular abnormalities. Thus, unlike many other hereditary diseases, there are no uniquely characteristic symptoms in their entirety.
Myotonic dystrophy is a chronic disease that is inherited. It affects about 3% of the world's population. The hereditary defect is inherited from the mother. Manifests itself as muscle weakness, muscle atrophy and autonomic dysfunction. Difficulties with diagnosis (since nonspecific symptoms associated with this pathology occur in other people), limited ability to work, and possible deaths lead to knowledge of this disease by a narrow circle of specialists.
