Aicardi-Goutieres syndrome is an inherited condition that mainly affects the brain, immune system, and skin.[1] It is characterized by early-onset severe brain dysfunction (encephalopathy) that usually results in severe intellectual and physical disability.[2] Additional symptoms may include epilepsy, painful, itchy skin lesion (chilblains), vision problems, and joint stiffness.[1] Symptoms usually progress over several months before the disease course stabilizes. There are six different types of Aicardi-Goutieres syndrome, which are distinguished by the gene that causes the condition: TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, and ADAR genes.[3] Most cases are inherited in an autosomal recessive pattern, although rare autosomal dominant cases have been reported. Treatment is symptomatic and supportive.[4]
