Myotonic dystrophy: genetics and clinical polymorphism

Cover Page

Full Text


Myotonic dystrophy is the most common form of hereditary progressive muscular dystrophy in adults. The disorder is characterized by progressive course, autosomal
dominant inheritance and multisystem involvement (skeletal muscles, myocardium, endocrine system, eyes, etc.). The paper highlights a huge heterogeneity of
clinical manifestations of myotonic type 1 and type 2, and reviews genetic aspects and current approaches to the diagnosis of myotonic dystrophy. We present our
own clinical observation of myotonic dystrophy in a family, which demonstrates a rare combination of a classical form of myotonic dystrophy type 1, syringomyelia
and proximal muscle weakness, and provides an classical example of the phenomenon of anticipation.
