Are you at a higher risk for diabetes? Check your TCFL72 variants

Type-2 diabetes affects about 9% of the US population and millions other world-wide. In those over age 65, one in four people has type-2 diabetes. While the overall numbers are a bit staggering, it is interesting to note that the peak for new cases was in the '90s with a decrease in cases from 2005-2017.[ref] Diabetes is thought to be caused partly by environment and partly due to genetics. Genetic susceptibility has been linked to a number of different genes, but one that stands out as being particularly relevant to almost all populations is the TCF7L2 gene. The TCF7L2 (transcription factor 7-like 2) gene is involved in the regulation of blood glucose level with insulin by affecting the expression of pro-glucagon.  Variants in TCFL2 are tied to type-2 diabetes, obesity, higher BMI,  and larger waist circumference. The SNPs listed below have been found to up-regulate TCF7L2 in pancreatic beta cells.[ref]  The up-regulation is thought to impair insulin secretion from the beta cells rather than causing insulin resistance. [ref] [ref] Why is this important? If you have one of the TCF7L2 variants that increase your risk of diabetes, there are lifestyle and diet choices that have been shown in studies to negate that increased risk. (more…)
