The simultaneous consideration of the expression levels of both gene and protein suggested a positive correlation between relative DMKN levels with the routine diagnostic biomarkers of MM such as Melan-A (r = 0.054; p = 0.011), Ki67 (r = 0.08, p = 0.034), and BRAF (r = 0.012; p = 0.044). The gene discussed is MKI67; the disease is Miyoshi myopathy.
