| Polymyositis and dermatomyositis are inflammatory
muscle diseases characterized by muscle weakness and
atrophy of the peripheral muscles.
Autoantibodies directive against the Jo-1 antigen can
be found in 30 – 40 % of all patients suffering from
polymyositis. Additionally, those patients manifest
fibrosing alveolitis, Raynaud's phenomenon and features
of scleroderma. Jo-1 is synonymous with HistidyltRNA-
Synthetase. |
