TEDDY study adds to a growing body of evidence that type 1 diabetes is not a single disease

Fri, 10/22/2021 - 10:55
New findings from the international The Environmental Determinants of Diabetes in the Young (TEDDY) study add to a growing body of evidence indicating that type 1 diabetes is not a single disease. The presentation and, perhaps, cause of autoimmune diabetes differs among genetically high-risk children, the research suggests.
