Quantitative analysis of lineage-specific chimerism at the time of last follow-up in 154 WAS-transplanted patients who had at least 12 months of follow-up after HCT. The percentage of donor-derived T, B, and myeloid cells is reported for each patient. (A) Data of lineage-specific chimerism at the time of last follow-up visit. Patients are grouped according to follow-up interval, and the number of patients studied at each interval is indicated in parentheses. (B) Patients are grouped according to donor type, and the number of patients receiving HCT from a specific type of donor is indicated in parentheses. *P < .05. Horizontal bars represent mean values (A-B).
