Intraclonal diversity in TCRBCL. Genealogical trees for the potentially functional rearrangements with intraclonal diversity. Letters and figures in the rectangles are the designations of the germline genes with the greatest homologies. Assumed intermediates in the genealogical trees are designated with X and Y. Figures in the circles indicate how often a specific sequence variant was found. Beside the lines connecting the sequence variants, positions of nucleotide exchanges and the new nucleotides are given. Mixed clonal sequences are excluded from this figure.
