Therefore, we isolated fibroblasts from patients with Aicardi-Goutières syndrome (AGS) (mutation in adenosine deaminases acting on RNA (ADAR)) and STING-associated vasculopathy with onset in infancy (SAVI)/chilblain lupus (mutation in STING). The gene discussed is ADAR; the disease is STING-associated vasculopathy with onset in infancy.
