Genetic Polymorphism and Alcohol Metabolism

Abstract

Throughout the world, human population experiment with alcohol, result into short-and long-term consequences including increased risk of accidental injuries, risky sexual behavior and lower education attainment. Due to polymorphism in the gene whose product enzymes are responsible for alcohol metabolism, serious health consequences including liver cirrhosis and hepatocarcinoma can occur. Enzyme alcohol dehydrogenase, CYP450 and catalase are alcohol metabolizing enzymes. Polymorphism in any one or all of the enzymes will result in defective alcohol metabolism and acetaldehyde accumulation cause serious health problems. This article mainly focuses on the consequences of alcohol consumption at genetic level that ultimately affect alcohol metabolism resulting in various health disorders.
