For example, antibodies directed against cobalamin binding intrinsic factor (CBLIF, also known as GIF), glutamate decarboxylase (GAD; Box 1) and GA-binding protein transcription factor subunit beta 2 (GABPB2) are associated with the development of pernicious anemia, vitiligo and autoimmune hepatitis, respectively (Fishman et al., 2017). This evidence concerns the gene GABPB2 and pernicious anemia.
