Comparison of CCND1 and CCND2 in expression for each clonal plasma cell revealed that MM clones and MGUS clone no. 1 with t (11;14) expressed high levels of CCDN1, while POEMS clones expressed low levels of CCDN1 (Figure 4C and Supplemental Figure 4). The gene discussed is CCND2; the disease is Miyoshi myopathy.
