Normal allele: CC
This is one of two SNPs in the TCF7L2 gene that have been reported to be strongly associated with type 2 diabetes, the other being rs4506565. They have approximately equal power to assess the risk of developing type 2 diabetes , and the results of one test correlate with the other in 92% of cases. Associated with reduced insulin secretion, as measured by the acute response to insulin and increased rate of glucose production in the liver.
