Lymphoid signature: T and B lymphopenia with hypergammaglobulinemia. (A) T cell genes, and the Ig genes. Median expression and the number of patients who display more than twofold increase (red) or decrease (blue) in gene expression. (B) Flow cytometry analysis of purified B cells showing the high frequency of CD19+CD38high plasmablasts. (C) IgG transcript levels correlate with plasmablast numbers.
