NRAS and lymphoma: DNA sequencing and qPCR CNV analysis of individual clones confirmed a single barcode integration and coalescing lesions in Cdkn2a and Bcor in lymphoma #4242, and Cdkn2a and Nras lesions in lymphoma #6066, confirming that both genetic lesions detected in the two lymphomas must be present in the same cell (Supplementary Fig. 8).
