Extended Data Fig. 8: Integration site (IS) analyses.

Panel A, The number of unique ISs detected in PBMCs at various points (in months) after gene therapy. Most of the samples were analyzed by sonic shearing in Illumina sequencing experiments (triangle), except that the early samples were analyzed using restriction endonucleases in 454 sequencing experiments (circle). Panel B, The Pielou diversity index for the IS population in PBMCs for the different patients. Panel C, A stacked bar representation showing the relative clone size (sonic abundance) of the TOP15 integration site clones detected over time for each patient.
