Gene Variation Helps Survivors of Sexual Abuse from Alcohol Addiction
Researchers at Washington University School of Medicine in St. Louis found that some adults who were sexually abused as children were protected from alcohol addiction due to a gene variant which offered them that protection against alcohol abuse.
According to the researchers, the finding could aid the development of therapies for alcohol dependence by offering suggestions for targeted treatments based on genetic traits and history of exposure to severe stressors.
Scientists estimate that about half the risk for alcoholism is encoded in a person's genes. The rest comes from environmental factors, such as age at first drink and exposure to extreme stress.
Other research has suggested that when the environmental risk factors occur during key periods of brain development, genes and environment working together can increase the likelihood an individual will become alcohol dependent.
Child sexual abuse is one of the environmental stressors that can interact with genes to significantly increase the risk for alcohol problems.
But a new study has shown that people with a particular pattern of genetic markers seem to be protected against alcohol problems, even if they were sexually abused as children.
