Viral Infections, Predisposition panel [21 genes]

Predisposition to viral infections comprises PIDs that are caused by defects in antiviral sensing and effector pathways, including Toll-like receptor 3 (TLR-3), type I and III interferons (IFNs), STATs, and interferon-stimulated genes. These pathways are critical for virus recognition and inhibition.

Clinical features

  • Susceptibility to CMV, VZV, HPV
  • Onset: Infancy, adulthood (rare)

Prevalence
