A new study demonstrates that a copy number variation affects a person's risk of developing type 2 diabetes in later life.
Amylase is an enzyme present in saliva that breaks down starches into sugar. The enzyme is encoded by the AMY1 gene, but the number of copies of this gene present in the genome can vary from around two to 20. Researchers at Cornell University in New York found that people with fewer copies of AMY1 are more likely to develop type 2 diabetes.
