Autoimmune Lymphoproliferative Syndrome
Gene: ITK
7 individuals from 5 unrelated families reported homozygous (missense/ nonsense) ITK variants consistent with Lymphoproliferative syndrome phenotype.
Two ITK-deficient mouse models demonstrated reduced T cells (CD4+), causing decreased CD4 to CD8 ratio.
Patients displayed early onset of features typically including fever, lymphadenopathy, autoimmune disorders, low immunoglobulins and high EBV viral load.
