This simple genetic analysis can explain why affected individuals suffer from unpleasant side effects even after consuming only a small quantity of alcohol. It is very useful to identify individuals that are at increased risk of health complications (e.g. esophageal cancer and liver disease).
These at-risk individuals can minimize their health risks by eliminating their alcohol intake. This analysis can also be beneficial for individuals who have a family member who suffers from alcohol dependency. An understanding of the genetic factors contributing to this problem allows individuals to obtain support and avoid environmental factors that influence the risk of alcoholism.
