A. Malandrini et al., EARLY-ONSET BENIGN LIMB-GIRDLE MYOPATHY WITH CONTRACTURES AND FACIAL INVOLVEMENT AFFECTING A FATHER AND DAUGHTER, Journal of the neurological sciences, 132(2), 1995, pp. 195-200
We describe a father and daughter with early-onset benign limb-girdle
myopathy and contractures of elbows and hands, resembling Bethlem dise
ase. Muscle biopsy showed a pattern of dystrophy with non specific mit
ochondrial changes. In both patients there was unusual facial muscle w
eakness. We discuss the nosological position of Bethlem myopathy and s
uggest that facial involvement may be an additional feature of this di
sease.
