The first polymorphisms in the AKR1B1 gene were identified in 1993 (54). A number of additional polymorphisms have been identified in the AKR1B1 gene. Of particular interest has been the (AC)« microsatellite dinucleotide repeat sequence polymorphism in the 5' region of the gene. This dinucleotide repeat polymorphism designated 5' ALR2 is located approximately 2.1 kb upstream of the initiation site of ALR2 close to the ORE sequences. A C-106T SNP situated in the basal promoter region of the ALR2 gene has also been studied, as well as a A(+11842)C SNP within intron 8. Finally, a C(-12)G SNP has also been reported (55).

Diabetes 2

Diabetes is a disease that affects the way your body uses food. Normally, your body converts sugars, starches and other foods into a form of sugar called glucose. Your body uses glucose for fuel. The cells receive the glucose through the bloodstream. They then use insulin a hormone made by the pancreas to absorb the glucose, convert it into energy, and either use it or store it for later use.
