Genetic Defences Against Alcohol Linked To Heart Disease And Mental Health, Study Finds

A study has unveiled significant connections between gene variants influencing alcohol use and a range of non-alcohol-related health conditions.

New research reveals a twist on genes that protect against heavy drinking. While these genes offer a shield against alcoholism, they may also be linked to other health conditions.

Scientists conducted a large-scale DNA analysis, examining over 3 million genetic records. They focused on variations in genetic code known as SNPs, which have previously been tied to both lower alcohol consumption and a reduced risk of alcohol use disorder (AUD).

These "lightweight genes" sometimes trigger unpleasant reactions to alcohol, like nausea, acting as a built-in deterrent to overconsumption.
