Age distribution and prevalence in different age groups of four myositis‐specific autoantibodies, including anti‐ARS, anti‐MDA5, anti‐Mi‐2, and anti‐TIF1γ antibodies

Abstract

Myositis-specific antibodies (MSAs) are antibodies that against cytoplasmic or nuclear component involved in the regulation of protein synthesis in patients with idiopathic inflammatory myopathies (IIMs). They have been shown to be highly specific, be able to predict clinical features, and have prognostic implications in patients with IIMs. [1][2][3] In Japan, an enzyme-linked immunosorbent
