KCNJ11 and type 2 diabetes mellitus: GDM studies in Indian women identified insertion and deletion of mitochondrial tRNA genes associated with GDM, and SNPs identified in the Potassium Inwardly Rectifying Channel Subfamily J Member 11 (KCJN11) and the Growth factor receptor-bound protein 14 (GRB14, which encodes a protein that interacts with insulin and insulin-like growth-factor receptors) genes were also associated with GDM and type 2 diabetes (T2D) [5,7].
