The average person's risk of developing type 2 diabetes is about seven percent. Now an Icelandic biotech company has developed the deCODE T2™ test, an assessment that tells you if your risk is double that.

The deCODE test detects a version of a single SNP (single nucleotide polymorphism) - a one-letter variation in the gene sequence. This risk variation is located on chromosome 10, within the gene called transcription factor 7-like 2 (TCF7L2). We all have two copies of that gene, one from our mother and one from our father. When both copies of the gene carry the variation, there's a doubled risk of type 2 diabetes.

To take the test, you swab a sample of DNA from your inner cheek and ship it off for testing. About three weeks later, you get the results in the mail. Ryan Phelan, CEO of DNA Direct, which markets the test, says, "The deCODE test can provide new insight for those concerned about the possibility of developing type 2 diabetes. The results of this genetic test, along with the support provided by our team of genetic counselors, can help people understand their risk of developing this disease and provide them with valuable information to help prevent the onset of disease."
