|(A;T)||1.5||1.4x increased risk for type-2 diabetes|
|(T;T)||2||1.9x increased risk for type-2 diabetes|
The risk allele (oriented to the dbSNP entry) is (T); the odds ratio associated with heterozygotes is 1.36 (CI 1.2-1.54), and for homozygotes, 1.88 (CI 1.56-2.27). [PMID 17554300]
Note: this is one of two SNPs within the TCF7L2 gene that have been reported to be associated with type-2 diabetes, the other being rs7903146. They have approximately equal power to estimate risk for type-2 diabetes, and the results from one correlate 92% of the time with the other.
