Intelligence and the gene for Duchenne muscular dystrophy.

Abstract

Duchenne muscular dystrophy (DMD) is a primary myopathy determined by an X-linked gene. In addition to causing muscle wasting and physical disability, DMD is associated with a concomitant reduction in intellectual functioning. This paper reports data obtained by psychometric evaluation of a series of patients with DMD, their sibs, and of heterozygous female relatives of these patients (carriers).
