This gene is called KLB

a Group of scientists from USA, Japan and several European countries conducted a major study, the results of which were able to identify the relationship between the genome of the KLB and the degree of addiction of a person to alcohol. Perhaps in the future, the information obtained will allow you to create new methods of dealing with alcoholism.

Initially experts relied on the results of another study, which was published about a year ago. Then biologists have found that the tendency to alcohol consumption and the risk of developing alcoholism affects the hormone FGF 21, synthesized by the liver and, as had previously been known to affect food habits in General. However, the relationship between this hormone and the likelihood of developing alcoholism was not well understood, and in order to fill this gap, researchers examined the genomes of 100 of thousands of people and find out how often and drank a lot each of these people.
As it turned out, largely on the likelihood of the person the excessive craving for alcohol was affected by the KLB gene and its various mutations. Subsequently, these findings could be confirmed in the experiment on laboratory mice are rodents that have a gene KLB “turned off”, would much rather used to drink alcohol than others.
In a sense, this means that the KLB gene might be more appropriately called not the “main gene for alcoholism” and “major gene protection from alcoholism”. However, in such situations, scientists are often encouraged to refrain from any generalizations of this kind: the genetic component is only one of many factors that determine the nature, habits and preferences of the person, and not always it is he is decisive. However, the researchers hope that their findings can be used to help many people to recover from alcoholism.
