MCP-1 was detected in plasma samples from all patients and healthy controls, and no significant differences were found between MM patients (median 105.6 pg/mL, range 8.3–299.5 pg/mL) and healthy controls (median 103.5 pg/mL, range 69.5–175.2 pg/mL; p = 0.83). This evidence concerns the gene CCL2 and Miyoshi myopathy.
