Emery-Dreifuss syndrome.
Emery-Dreifuss syndrome is a heterogeneous entity characterized by the following clinical triad: early contracture of the elbows. Achilles tendons and postcervical muscles; slowly progressive muscle wasting and weakness with a humeroperoneal distribution early in the course of disease; and a cardiomyopathy usually presenting as an atrioventricular block ranging from sinus bradycardia to complete heart block. As the heart block is the major problem, insertion of a cardiac pacemaker can be life saving. Recent advances through genetic and immunochemical studies have provided valuable clues to the understanding and the early diagnosis of this disease.
