Myotonic Dystrophy Overview Myotonic dystrophy is a genetic disorder characterized by progressive muscle wasting and weakness. It is caused by mutations in specific genes that lead to an abnormal expansion of repetitive DNA sequences. The two main types of myotonic dystrophy are Myotonic Dystrophy Type 1 (DM1) and Type 2 (DM2). DM1 is caused by a CTG repeat expansion in the DMPK gene, while DM2 is linked to a CCTG repeat expansion in the CNBP gene. Symptoms of myotonic dystrophy can vary but often include muscle stiffness (myotonia), weakness, and atrophy, primarily affecting the distal muscles and those of the face. Additional symptoms may involve cataracts, cardiac arrhythmias, endocrine issues, and cognitive difficulties. Diagnosis typically involves a combination of clinical evaluation, family history assessment, and genetic testing to identify the specific mutations. Electromyography can also be used to detect myotonia. Currently, there is no cure for myotonic dystrophy, and treatment focuses on managing symptoms. This may include physical therapy to maintain muscle function, medications to alleviate myotonia, and regular monitoring for cardiac issues. Genetic counseling is recommended for affected individuals and their families to understand the inheritance patterns and potential risks.
