Dr Mariko Bennett and Dr Laura Adang discuss the precarious balance between a protective and a destructive immune response, as is seen in inborn errors in nucleotide metabolism. Our discussion focuses on the most common of these disorders: Aicardi Goutières syndrome (AGS). Sadly, despite the many gains in understanding about AGS, there remain many gaps in our understanding of this condition.
