Atanackovic et al. [59], evaluating the prognostic value of MAGE-C1/CT7 expression in MM, demonstrated that patients undergoing allogeneic hematopoietic stem cells transplant showed early recurrence and worse overall survival when the malignant plasma cells from bone marrow expressed MAGE-C1/CT7. Here, MAGEC1 is linked to Miyoshi myopathy.
