Abstract

Congenital myotonic dystrophy is an almost always maternally-inherited autosomal dominant multisystem disorder of variable clinical expressions characterized by hypotonia and frequent respiratory distress at birth. The muscle weakness may be so severe, it may lead to death in the newborn period. We report a case of congenital myotonic dystrophy in a 34 weeks of gestational age premature infant born to a mother with polyhydramnios, presenting with hypotonia, respiratory insufficiency, feeding difficulties and arthrogryposis. A brief review of literature is given.
