Variant of transcription factor 7-like 2 (TCF7L2) gene confers risk of type 2 diabetes

We have previously reported suggestive linkage of type 2 diabetes mellitus to chromosome 10q 1 . We genotyped 228 microsatellite markers in Icelandic individuals with type 2 diabetes and controls throughout a 10.5-Mb interval on 10q. A microsatellite, DG10S478, within intron 3 of the transcription f...

description We have previously reported suggestive linkage of type 2 diabetes mellitus to chromosome 10q 1 . We genotyped 228 microsatellite markers in Icelandic individuals with type 2 diabetes and controls throughout a 10.5-Mb interval on 10q. A microsatellite, DG10S478, within intron 3 of the transcription factor 7–like 2 gene ( TCF7L2 ; formerly TCF4 ) was associated with type 2 diabetes ( P = 2.1 × 10 −9 ). This was replicated in a Danish cohort ( P = 4.8 × 10 −3 ) and in a US cohort ( P = 3.3 × 10 −9 ). Compared with non-carriers, heterozygous and homozygous carriers of the at-risk alleles (38% and 7% of the population, respectively) have relative risks of 1.45 and 2.41. This corresponds to a population attributable risk of 21%. The TCF7L2 gene product is a high mobility group box–containing transcription factor previously implicated in blood glucose homeostasis. It is thought to act through regulation of proglucagon gene expression in enteroendocrine cells via the Wnt signaling pathway 2 .

We genotyped 228 microsatellite markers in Icelandic individuals with type 2 diabetes and controls throughout a 10.5-Mb interval on 10q. A microsatellite, DG10S478, within intron 3 of the transcription factor 7–like 2 gene ( TCF7L2 ; formerly TCF4 ) was associated with type 2 diabetes ( P = 2.1 × 10 −9 ). This was replicated in a Danish cohort ( P = 4.8 × 10 −3 ) and in a US cohort ( P = 3.3 × 10 −9 ). Compared with non-carriers, heterozygous and homozygous carriers of the at-risk alleles (38% and 7% of the population, respectively) have relative risks of 1.45 and 2.41. This corresponds to a population attributable risk of 21%. The TCF7L2 gene product is a high mobility group box–containing transcription factor previously implicated in blood glucose homeostasis. It is thought to act through regulation of proglucagon gene expression in enteroendocrine cells via the Wnt signaling pathway 2 .</abstract><cop>New York</cop><pub>Nature Publishing Group US</pub><pmid>16415884</pmid><doi>10.1038/ng1732</doi><tpages>4</tpages></addata></record>
