Myotonic dystrophy type 2 is characterized by large CCUG repeats in the CNBP gene that result in myopathy. Here, the authors show that recognition of aberrant protein translation derived from these repeats leads to ER stress and mitochondrial DNA release, leading to cGAS/STING activation and type-I IFN responses.
