Until recently, most research has investigated causes of disease in “coding” genes—those that produce proteins. Now, academics at the University of Exeter and their international collaborators have found that DNA changes in two genes that instead make functional RNA molecules are a cause of diabetes. RNA plays various roles in the body, including regulating genes and influencing how genetic information is “read” and interpreted.

The study is titled “Bi-allelic variants in the non-protein-coding minor spliceosome components RNU6ATAC and RNU4ATAC cause syndromic monogenic autoimmune diabetes,” and was published in the American Journal of Human Genetics.
