These serum parameters reflecting the tumor load of MM, not only relate to the clinical stage, but also affect the renal function and prognosis of MM patients.27, 28, 29 In our previous study, we demonstrated that these serum indicators were related to MM prognosis.30 In present study, multivariate logistic regression analysis showed miR‐107, miR‐15a‐5p, and Hb were potential diagnostic biomarkers for the identification of MM and MUGS. The gene discussed is GSTM1; the disease is Miyoshi myopathy.
