Myotonic Dystrophy 1
This is one of the more common hereditary disorders of muscle function, and is sometimes called a form of muscular dystrophy. It causes widespread disease in other organs however.
What is myotonic dystrophy?
Myotonic dystrophy is an inherited disorder of the muscles and other body systems. It is the most common form of muscular dystrophy that begins in adulthood.

Myotonic dystrophy
Also known as Steinert's disease, this form of muscular dystrophy produces stiffness of muscles and an inability to relax muscles at will (myotonia), as well as the muscle weakness of the other forms of muscular dystrophy.
myotonic dystrophy - an inherited condition with progressive multi-system involvement, resulting in infertility (underdeveloped testes and abnormal sperm production), in some cases.
Myotonic dystrophy is due to a trinucleotide repeat (a "stuttering" sequence of three bases) in the DNA. The myotonic dystrophy gene (called DM1), found on chromosome 19q13.3, codes for a protein kinase (an enzyme) that is found in skeletal muscle.

Myotonic dystrophy affects multiple body systems, causing muscle loss and weakness, especially in the facial muscles, arms, and legs.
Definition Myotonic dystrophy is a progressive disease in which the muscles are weak and are slow to relax after contraction.

muscular dystrophy, myotonic dystrophy). In neurogenic atrophy, the nerve supply to the muscle can be interrupted or compromised by compression, injury, or disease within the nerve cells, resulting in temporary or permanent nerve deficit.
Myotonic dystrophy. This may be classified as a type of MD or as a neuromuscular disorder. It affects the 'small' muscles, such as those in the face, jaw, neck, and hands. Myotonic dystrophy may start at any age from birth to old age.
Hypotonia may be caused by trauma, environmental factors, or by genetic, muscle, or central nervous system disorders, such as Down syndrome, muscular dystrophy, cerebral palsy, Prader-Willi syndrome, myotonic dystrophy, and Tay-Sachs disease.
