Unusually high frequency of autoantibodies to PL‐7 associated with milder muscle disease in Japanese patients with polymyositis/dermatomyositis

Abstract

Anti-PL-7 was found at an unusually high frequency in this group of Japanese patients with myositis. Although anti-PL-7, similar to anti-Jo-1, is associated with PM/DM with ILD, muscle involvement in the patients with anti-PL-7 appeared to be milder than that in the anti-Jo-1 subset.
