The reaction is the result of polymorphisms in genes that regulate the immune system, according to Dr Christopher Day of the University of Newcastle-upon-Tyne, UK.
Dr Day said that the finding could make it possible to screen alcohol abusers to determine those at greatest risk of liver damage.
"Those with genes favoring a strong immune response are most at risk of alcoholic liver disease."
Dr Christopher Day.
He said: "Our study shows that individuals with genes favoring a strong immune response are those most at risk of alcoholic liver disease.
"This suggests directions for the development of treatment and should allow for the identification of individuals at high risk of developing the disease, before they consume excessively."
According to his research, alcohol metabolites alter proteins in the liver into foreign antigens, provoking a destructive attack by the enhanced immune system.
