In a study investigating genetic predisposition of alcohol drinking problems, a new study has identified up to 29 genetic variants that may play a role in alcohol abuse disorder. This new data triples the number of known gene variants that were associated with alcohol drinking problems.
This study, which involved people of European ancestry, found 19 newly discovered genetic risk factors for problematic alcohol use and confirmed 10 previously identified genetic factors.
This study also involved analyzing genetic risk factors for various psychiatric disorders, and how they are related to genetic variants that increase the risk of problematic alcohol use. The researchers were able to identify common genetic links between problematic drinking and psychological disorders such as depression and anxiety.
Now we know more about how genetic risks may predispose to alcohol drinking problems and how the risk may be associated with other psychological disorders.
