Similarly, apart from association to GDM, KCNQ1 protection haplotype TTT (r2 rs2237892 vs. rs163184 = 0.41, r2 rs2237892 vs. rs2237897 = 0.91, r2 rs163184 vs. rs2237897 = 0.39) was also associated to lower levels of 60’ and 180’ OGTT glycemia, and area under the curve (Table 3). The gene discussed is KCNQ1; the disease is gestational diabetes.
