This review highlights the roles of specific DNA sensors, such as cyclic AMP‐GMP synthase and stimulator of interferon genes (cGAS‐STING), absent in melanoma 2 (AIM2), toll‐like receptor 9 (TLR9), interferon gamma‐inducible protein 16 (IFI16), DNA‐dependent protein kinase (DNA‐PK), and DEAD‐box helicase 41 (DDX41) in various metabolic disorders. This evidence concerns the gene DDX41 and metabolic disease.
