ABSTRACT
Objective To investigate the clinical and pathological features of Miyoshi myopathy(MM) with dysferlin protein deficient. Methods The clinical and pathological data of the 3 patients with MM were analysed. Results 3 patients were onset at youngster.The clinical manifestation were myastheria and myoatrophy in distal of lower limbs.1 case combined myalgia and tumefaction in lower limbs at early stage of onset;1 case showed myathenia in proximal of lower limbs.The level of serum creatine phosphokinase (CK) was significantly ligher in the 3 cases (7543 IU/L, 5657 IU/L, 8721 IU/L respectively). The level of serum lactic dehydrogenase (LDH) was significantly higher in the 2 cases (456 IU/L ,636 IU/L respectively).The result of muscle pathology was showed myogenic damage in all the cases. The expression of dysferlin protain in membrane of muscle cells was completely deficient, although the expression of dystrophin was normal. Inflammatory cells infiltration was found in 1 case's muscle tissue. Conclusions The clinical characters of MM patient are onset at youngster,myasthenia and myoatrophy in lower limbs.The deficit of dysferlin protain can be found by pathology.
