Myotonic Dystrophy

What is Myotonic Dystrophy?

Myotonic Dystrophy (DM) is a muscle weakening disorder which is inherited. It is abbreviated to DM because the Latin name for this condition is 'Dystrophia Myotonica'. In DM, a defective gene causes progressive muscle weakness accompanied by delayed relaxation of muscles after contraction which is called myotonia. It is a multi-systemic disorder, this means that  the effects are not limited to the voluntary muscle system, but can also affect tissues and organs throughout the body. Primarily the muscles of the face, neck, hands, forearms and feet are affected, although DM can have a wide range of different effects on different individuals.

This diagram shows the location of the genetic error which causes myotonic dystrophy,. One copy of the gene with an error is enough to cause the condition. Type 1 is caused by an error in the DMPK gene on chromosome 19 and Type 2 is caused by an error in the CNBP gene on chromsome 3.
