The results showed ≥20% of CD138+ cells with three or more signals marked as NEK2 loci in 100% (4/4) of TP53Del MM samples (P31‐34, Table S1, Supporting Information), but not in seven TP53WT samples (P25‐30, Table S1, Supporting Information) (Figure 2G). This evidence concerns the gene SDC1 and Miyoshi myopathy.
