my·o·ton·ic dys·tro·phy

[MIM*160900] the most common adult muscular dystrophy, characterized by progressive muscle weakness and wasting of some of the cranial innervated muscles, as well as the distal limb muscles; other clinical features include myotonia, cataracts, hypogonadism, cardiac abnormalities, and frontal balding; onset usually in the the third decade; autosomal dominant inheritance caused by abnormal trinucleotide repeat expansion in the dystrophia myotonica protein kinase gene (DMPK) on chromosome 19q. This disorder demonstrates anticipation (increase in severity in successive generations because of successive amplification of the trinucleotide repeats); the severe congenital form is almost always confined to the children of affected women. Synonym(s): dystrophia myotonica, myotonia atrophica, myotonia dystrophica, Steinert disease

dystrophia myotonica

A hereditary AUTOSOMAL DOMINANT condition which presents in early adult life with wasting of the muscles of the face, neck and shoulders and spreads to the arms and legs. The muscles relax very slowly after contracting. The condition also features drooping eyelids (PTOSIS) and CATARACT.
