Introduction:
GAD65 is primarily expressed in neuron cells and pancreas 𝜷-cells. It works as a catalyser in GABA synthesis.
Glutamic acid decarboxylase autoantibodies (GADA) are found in 70% to 80% of individuals with new-onset type 1 diabetes, making it the most frequent autoantibody in autoimmune diabetes. GADA can be detected in serum for many years post diagnosis, and high concentrations of GADA have been considered as a marker of faster 𝜷-cell exhaustion in these patients. Furthermore, GADA in nondiabetic individuals predicts the later development of type 1 diabetes1. Besides autoimmune diabetes, GADA also exists in Stiff Man Syndrome, autoimmune polyendocrinopathies, and some of Grave’s Disease patients.
