Binge drinking negates protective gene

A gene variant has been shown to protect against alcohol use disorders (AUD) but any genetic protection may be lost for life in teens who binge drink, a study finds.

Explaining the interplay between ‘peer drinking’ and genetic risk, lead author Dr Emily Olfson says the “modifiable risk factor of ‘best friends drinking’ eliminates the protective effects of the ADH1B variant for the development of adolescent drinking behaviours”.
