Correlation of the most differentially specifically overexpressed genes in patients with anti-Mi2-positive dermatomyositis and: titer of anti-Mi2 autoantibodies by ELISA (Mi2t), type 1 interferon-inducible genes (ISG15, MX1), type 2 interferon-inducible genes (GBP2, IFI30), T-cell markers (CD3E, CD4, CD8), macrophages (CD14, CD68), markers of muscle differentiation (NCAM1, MYOG, PAX7, MYH3, MYH8), and structural mature muscle proteins (ACTA1, MYH1, MYH2).
