Phytohemagglutinin responses at the time of IKBKB diagnosis by patient number. Percent of control is defined as the stimulation index of the patient relative to the average stimulation index of two healthy controls. Corresponding CD3 T-cell count (cells/μL) at the time of diagnosis is under each patient number. Patients 4 and 14 both had disseminated BCG with bone marrow involvement and severe cytopenias, including lymphopenia, which may have impacted PHA response.
