Case Report: Primary Immunodeficiencies, Massive EBV+ T-Cell Lympoproliferation Leading to the Diagnosis of ICF2 Syndrome

In immunocompromised patients, EBV may elicit B-cell transformation and proliferation. A 5-year-old microcephalic boy was admitted with fever and non-malignant polymorphic T-cell lymphoproliferative disease associated with EBV. A presumptive diagnosis of primary immunodeficiency with inability to co...

Description
Summary:In immunocompromised patients, EBV may elicit B-cell transformation and proliferation. A 5-year-old microcephalic boy was admitted with fever and non-malignant polymorphic T-cell lymphoproliferative disease associated with EBV. A presumptive diagnosis of primary immunodeficiency with inability to control EBV was made and next-generation sequencing led to the identification of a novel ZBTB24 mutation (ICF2-syndrome). This case shows that susceptibility to EBV seems to be particular of ICF-2 as it has not been described in the other types of ICF. It is mandatory to raise the hypothesis of an underlying PID in case of severe EBV infection.
