Abstract
Early environmental factors and genetic variants have been reported to be involved in the pathogenesis of type 2 diabetes The aim of this study was to investigate whether there is an interaction between birthweight and common variants in the TCF7L2 HHEX PPARG KCNJ11 SLC30A8 IGF2BP2 CDKAL1 CDKN2A/2B and JAZF1 genes in the risk of developing type 2 diabetesLow birthweight was associated with type 2 diabetes p = 0008 and impaired insulin secretion p = 004 Of the tested variants the risk variant in HHEX showed a trend towards a low birthweight p = 009 and the risk variant in the CDKN2A/2B locus was associated with high birthweight p = 001 The TCF7L2 risk allele was associated with increased risk of type 2 diabetes Pooling across all nine genes each risk allele increased the risk of type 2 diabetes by 11 Risk variants in the HHEX CDKN2A/2B and JAZF1 genes interacted with birthweight so that the risk of type 2 diabetes was highest in those with lower birthweight p ≤ 005 The interaction was also present in the pooled data
