A family of autosomal dominant facio-limb-girdle muscular dystrophy was reported. The proband was a 28-year-old male. His father and sister suffered from a similar disease. All patients developed weakness of lower limbs and atrophy of thigh at second to fourth decades. All showed mild facial and neck flexor weakness as well as proximal dominant weakness and atrophy of four limbs. Limb muscle involvement was more severe in lower limbs than in upper limbs in all cases. Interestingly, all showed limitation of ankle dorsiflexion (tight heel cord), although distal muscles of lower limbs were not involved or only mildly involved clinically. On laboratory examination, serum CK increased slightly. Needle EMG revealed low amplitude, polyphasic MUP in limb muscles in all cases. Biopsied muscles taken from the proband showed non-specific myogenic changes. Rimmed vacuoles were not observed. Our cases were different from Bethlem myopathy, because the age of onset was late and joint contractures were mild in our cases, as compared with Bethlem myopathy. Clinical manifestations of our family showed a strong resemblance to the family reported by Girchlist et al, but similar cases were not reported in Japan.
