Selected subclone from the LN in the PB. Shown is a schematic representation of a selected subclone from the LN sample in the PB of case 1. In the LN sample of case 1, at least 4 subclones exist: a subclone with chromosome 3 and 7 aberrations; a subclone with additional chromosome 8 aberrations; a subclone with chromosome 3, 7, 8, and 2 aberrations; and a subclone with chromosome 3, 7, 8, and 9 aberrations. Among these subclones, a subclone with chromosome 3, 7, and 8 aberrations appeared in the PB sample.
