Additionally, three potential immune-related biomarkers (C-X-C Motif Chemokine Ligand 12 (CXCL12), Secretogranin II (SCG2), Roundabout Guidance Receptor 3 (ROBO3)) for EMs were identified and a diagnostic model based on these biomarkers was developed. Here, CXCL12 is linked to eosinophilia-myalgia syndrome.
