Myotonic dystrophy type 2, one of the two types of myotonic dystrophy, is an inherited type of muscular dystrophy that affects the muscles and other body systems (e.g., heart, eyes, pancreas). The condition is characterized by prolonged muscle tensing (myotonia) as well as muscle weakness, pain, and stiffness. Signs and symptoms of myotonic dystrophy usually develop during the twenties or thirties. Muscles in the neck, fingers, elbows, and hips are typically affected by this condition. Facial and ankle muscles may also be affected but are less commonly involved. The severity of myotonic dystrophy type 2 varies widely among affected individuals, even among family members. The condition is inherited in an autosomal dominant pattern and is caused by mutations in the CNBP gene. Treatment is based on the individual's specific signs and symptoms.
