Inherited Interleukin 2–Inducible T-Cell (ITK) Kinase Deficiency in Siblings With Epidermodysplasia Verruciformis and Hodgkin Lymphoma.

Biallelic mutations in the ITK gene cause a T-cell primary immunodeficiency with Epstein-Barr virus (EBV)–lymphoproliferative disorders. We describe a novel association of a homozygous ITK mutation with β–human papillomavirus (HPV)–positive epidermodysplasia verruciformis. Thus, loss of function in ITK can result in broad dysregulation of T-cell responses to oncogenic viruses, including β-HPV and EBV. [ABSTRACT FROM AUTHOR]
