CYP2C9 and Hypoglycemia: In this systematic review, we have included studies that investigated association between genetic variants in genes, CYP2C9 and ABCC8/KCNJ11, that encode CYP2C9 and SUR1/Kir6.2 with risk of hypoglycemia (Holstein et al., 2005, 2011, 2012; Ragia et al., 2009, 2012, 2014; Gökalp et al., 2011) (Table 4).
