Myotonic dystrophy with pregnancy.

ABSTRACT

Myotonic dystrophy is a rare heredodegenerative muscular disorder in which pregnancy is unusual. Because of the autosomal dominant inheritance of the disease, 50% of children of an affected parent may have the disease; 20% of them are asymptomatic at birth. Foetal involvement may be manifested by polyhydramnios, arthrogryposis multiplex in utero, respiratory difficulties, and floppiness at birth. A case of myotonic dystrophy with pregnancy is presented here.
