Abstract
We describe a father and daughter with early-onset benign limb-girdle myopathy and contractures of elbows and hands, resembling Bethlem disease. Muscle biopsy showed a pattern of dystrophy with non specific mitochondrial changes. In both patients there was unusual facial muscle weakness. We discuss the nosologic position of Bethlem myopathy and suggest that facial involvement may be an additional feature of this disease.
