However, IL1RL1 has not been widely described as a DM or JDM biomarker; one report showed a positive correlation between serum IL1RL1 and DM global disease activity [67] and another group reported a strong positive correlation between serum IL1RL1 and disease activity in idiopathic inflammatory myopathies [68]. This evidence concerns the gene IL1RL1 and dermatomyositis.
