IGF2 and Hyperglycemia: Meta-analysis of the associations including data from 1367 Hyperglycaemia and Adverse Pregnancy Outcome Study participants confirmed the paternally-transmitted fetal IGF2/INS SNP associations (rs10770125, P-value = 3.2 × 10–8, rs2585, P-value = 3.6 × 10–5) and the composite fetal imprinted gene allele score association (P-value = 1.3 × 10–8), but not the maternally-transmitted fetal KCNQ1(OT1) associations (rs231841, P-value = 0.4; rs7929804, P-value = 0.2).
