The use of sarcoglycan antibodies in diagnostic tests for sarcoglycanopathies / 中华神经科杂志

ABSTRACT

Objective To study the characteristics of sarcoglycanopathies and their diagnostic methods.Methods On basis of dystrophin immunostaining,the muscle specimens of 25 LGMD with normal dystrophin were investigated using all four sarcoglycan (?,?,?,? sarcoglycan) antibodies by immunohistochemistry and Western blotting. Results 5 specimens showed a deficiency one case in ? SG,two in ? SG,one in three SG,and one in all four SG.Conclusion 5 patients were diagnosed as "sarcoglycanopathies". As it is difficult to distinguish the various types of LGMD based on clinical features,the immunohistochemistry and Western blotting of all four sarcoglycan antibodies may serve as an important diagnostic tool for sarcoglycanopathies.
