摘要: We conducted a genome-wide association study for type 2 diabetes (T2D) in Icelandic cases and controls, we found that previously described variant the transcription factor 7-like gene (TCF7L2) conferred most significant risk. In addition to confirming two recently identified risk variants, CDKAL1 was associated with T2D individuals of European ancestry (allele-specific odds ratio (OR) = 1.20 (95% confidence interval, 1.13-1.27), P 7.7 x 10(-9)) from Hong Kong Han Chinese (OR 1.25 (1.11-1.40), 0.00018). The genotype OR this suggested effect substantially stronger homozygous carriers than heterozygous carriers. ORs homozygotes were 1.50 (1.31-1.72) 1.55 (1.23-1.95) groups, respectively. insulin response approximately 20% lower heterozygotes or noncarriers, suggesting confers through reduced secretion.
