Eventually, 5 genes that can be used as characterized genes of DM were identified, which were chromosome 1 open reading frame 106 (C1orf106), component of oligomeric Golgi complex 8 (COG8), envoplakin (EVPL), GTPases of immunity-associated protein family member 6 (GIMAP6), and interferon-alpha inducible protein 6 (IFI6) (Figures 4D–F). The gene discussed is COG8; the disease is dermatomyositis.
