Such correlations between CD4 and DNT proportion and absolute counts were maintained in patients with ALPS without CD4 lymphopenia (Pearson r: −0.74, p = 0.002, and 0.76, p = 0.0008, respectively) but were absent in patients with ALPS with CD4 lymphopenia (Supplemental Table 1). The gene discussed is CD4; the disease is autoimmune lymphoproliferative syndrome.
