This study done by the UT Southwestern Medical Center was the largest genome wide association meta analysis and replication study ever done which compares the DNA and genetics as whole of over 105,000 light and heavy drinkers. The researches claim to have found a gene variation in β-Klotho, while doing this study that is linked with the regulation of alcohol consumption. This less common variant was found in 40% of people throughout this study and is linked with decreased desire for alcohol consumption.
This could be a huge breakthrough finding as it can be possible that this study can lead to a mechanism in which we may be able to influence to reduce alcohol intake. This could be especially beneficial for people who are fighting alcoholism and are trying to stop. The study discusses how a lot of other research has been primarily focused on addiction, while this study has discovered something that comes before the addiction, consumption to begin with. More studies are being done on how to influence this gene but some are saying it may be able to be the development of a drug that would stimulate it. This could have incredible health benefits if testing goes well and it is proven safe. As decreasing someone from heavy drinker or alcoholic by simply taking away the desire to drink would help many peoples overall health. This large study could have huge benefits and it will be interesting to follow as more testing is done in the near future.
