An important gene associated with Polymyositis is RN7SL1 (RNA Component Of Signal Recognition Particle 7SL1), and among its related pathways/superpathways are miRNAs involved in DNA damage response and miRNA role in immune response in sepsis. The drugs Abatacept and Alendronic acid have been mentioned in the context of this disorder. Affiliated tissues include skeletal muscle and heart, and related phenotypes are hypotonia and autoimmunity
