In this study, we confirmed the prognostic value of well-known clinical factors (performance status, type of MM, the stage of disease, and kidney function) and laboratory biomarkers (hemoglobin, platelets, albumin, creatinine, calcium, LDH, β2-microglobulin, del(17p), and t(14;16)) in MM. Here, HLA-G is linked to Miyoshi myopathy.
