Autoimmunity and lymphoproliferation in TACI deficiency. Histograms show the prevalence of autoimmune diseases (top panel) and lymphoproliferation (bottom panel) as percentages in CVID patients without TACI mutation, TACI-deficient patients, and subgroups of TACI-deficient patients with homozygous or compound heterozygous, C104R heterozygous, or other heterozygous mutations. Absolute numbers of patients are printed on the bars.
