CCND1 and Miyoshi myopathy: Thus the genes dysregulated in these translocations are: 11q13 (CCND1 (cyclin D1 gene)), 4p16.3 (FGFR-3 and MMSET), 6p21 (CCND3 (cyclin D3 gene)), 16q23 (c-MAF), and 20q11 (MAF-B), respectively.16, 17, 18 A small subset of patients with MM has evidence of both trisomies and IgH translocations, but in general, the primary cytogenetic subtypes are considered to be non-overlapping.
