Genetic Variants and Immune Responses in a Cohort of Patients With Varicella Zoster Virus Encephalitis.

Background: Infection with varicella zoster virus (VZV) may involve different central nervous system (CNS) manifestations, including meningitis, encephalitis, and vasculitis. In cases in which otherwise healthy individuals are affected, an inborn error of immunity may underlie increased susceptibility or severity of infection.

Methods: We collected a cohort of 17 adults who experienced VZV encephalitis and performed whole exome sequencing.
