Type 1 diabetes (T1D) is an autoimmune disease resulting from the complex interaction between susceptibility genes and environmental factors. This disease has been used as a model system to elucidate the complex genetics involved in common diseases in the last 25 years. Despite the mapping of over 40 loci by genome-wide association studies, the specific genes and their underlying mechanisms of action remain largely elusive. Identification of ERBB3 as a gene involved in T1D and immune regulation significantly improves our understanding on how T1D susceptibility genes may interact with environmental triggers to predispose high risk subjects to the development of autoimmune diabetes.
