Genome-wide association and meta-analysis in populations from Starr County, Texas, and Mexico City identify type 2 diabetes susceptibility loci and enrichment for expression quantitative trait loci in top signals.
Results showed that the T2D risk alleles of rs243021 located near BCL11A, rs10830963 in MTNR1B, and rs2237895 in KCNQ1 were related to a lower risk for abdominal obesity in T2D patients (rs243021: 0.92 (0.84, 1.00), P = 4.42 × 10-2; rs10830963: 0.92 (0.85, 1.00), P = 4.07 × 10-2; rs2237895: 0.89 (0.82, 0.98), P = 1.29 × 10-2).
Of the 37 T2D risk alleles, two showed nominally significant positive associations with pancreatic cancer risk (FTO rs8050136 per-allele OR = 1.12; CI: 1.02-1.23; MTNR1B rs1387153 OR = 1.11; CI: 1.00-1.23) and one showed an inverse association (BCL11A rs243021 OR = 0.88; CI: 0.80-0.97).
