For instance, subclassifying MM patients according to the presence of IgH translocations and dysregulation of cyclin D genes (i.e., the translocation and cyclin D (TC) classification) allowed the identification of eight subgroups of MM (11q13, 6p21, 4p16, maf, D1, D1+D2, D2, and none) [69,70,71]. The gene discussed is MAF; the disease is Miyoshi myopathy.
