  • Data are from multivariate Cox proportional hazard analysis of time to onset of severe nephropathy. As of 2005, the number of severe nephropathy cases was 132 (vs. 1,172 censored). Chromosomal locations, SNP positions, and gene annotations are in reference to NCBI Build 36.1.

  • *The risk alleles that are presented are in reference to those identified in the GoKinD collection;

  • †one-sided P values (consistent with the current “best practices” for replication in GWA scans) (20–22) are used to test for the same direction of effect as in the GoKinD collection;

  • ‡rs1888746 was genotyped on an Illumina array in DCCT/EDIC and is in complete linkage disequilibrium (r2 = 1.0) with rs1888747 (genotyped using a Taqman assay in GoKinD);

  • §rs13289150 was genotyped on an Illumina array in DCCT/EDIC and is in complete linkage disequilibrium (r2 = 1.0) with rs10868025 (genotyped on an Affymetrix array in GoKinD).
