Similarly, other immunological biomarkers were similar between the two groups, while IPEX patients showed increased memory CD4+ T cells, increased eosinophils, and immunoglobulin E (IgE) levels, as seen in other immunodeficiencies with immune dysregulation [28–30]. The gene discussed is CD4; the disease is immune dysregulation-polyendocrinopathy-enteropathy-X-linked syndrome.
