Fig 1 Absence of CD27 expression because of a nonsense mutation in the CD27 gene. A, Family pedigree (/, deceased persons; double lining, consanguinity). B, FACS analysis of CD27 membrane expression on PBMCs. C, Sequence analysis of the CD27 gene. The mutation (boldface) identified in both patients in exon 1 results in a premature stop codon (X) in the signal peptide of the protein (NP_001233.1), as depicted in the protein sequence (superimposed on the gene sequence).

Fig 2 Phenotypic analysis of the index patient’s B cells. A, The presence of different B-cell subsets was analyzed by using FACS. Within the CD19+ B cells, the fraction of naive (IgM+ and IgD+) or memory (IgA+ or IgG+) B cells was determined. B, The presence of GCs was determined by staining tissue sections with anti-CD79a and anti-CD23 mAb. IF, Interfollicular area; MZ, mantle zone.

Fig 3 Functional analysis of the index patient’s B cells. A, PBMCs were tested for their capacity to differentiate into plasmablasts after T cell–independent (TI; SAC/IL2) or T cell–dependent (TD; PWM) stimulation. The fraction of plasmablasts was determined based on morphology and intracellular immunoglobulin staining on day 7. O, Index patient; -, control subjects. B, Vaccination response of the index patient to polysaccharide vaccine (Pneumovax 23) and conjugated polysaccharide Men C vaccine (NeissVac). C, Vaccination response of the index patient to protein antigen (diploid cell rabies vaccine). The mean of healthy control subjects (black line) with 95% CIs (gray region) is shown.

Results are presented as the stimulation index (index patient cpm/healthy control subject cpm). B, Subset analysis of T cells32 in PBMCs by means of FACS. Within CD8+CD3+ T cells, the fractions of naive (CCR7+CD45RO−), central memory (CCR7+CD45RO+), effector memory (CCR7−CD45RO+), and effector (CCR7−CD45RO+) cells were determined.

Fig E3 Absence of costimulation through the CD27 ligand CD70 of the index patient’s T cells. Purified CD4+ T cells from the index patient and 2 healthy control subjects were stimulated with PHA and mock transfectants (black bar), CD70 transfectants (gray bar), or CD70 transfectants and blocking CD70 mAb. Proliferation was measured based on tritiated thymidine incorporation and is depicted as the stimulation index (ratio [median cpm situation X]/median cpm + P815).
