Scientists have identified a particular variant of a gene that plays spoiltsport in people's recovery from alcoholism, besides subjecting them to 10 times higher risk of premature death.
"Our research shows that alcohol-dependent individuals, who are also carriers of this gene variant, run 10 times the risk of dying prematurely, compared with the average population," says study co-author Claudia Fahlke, from Sweden's Sahlgrenska Academy.
Sahlgrenska researchers have found that a variant of the dopamine D2 receptor gene is overrepresented in people with severe alcohol dependency, the journal Alcohol and Alcoholism reports.
The gene variant is linked to a number of different negative consequences that can be of vital bearing on the person affected, according to a Sahlegrenska statement.
This gene variant is tied with higher incidence of relapses among these individuals even if they have undergone treatment for their alcohol dependency, the researchers conclude.
