Best answer: Is there a genetic component to alcoholism?

Those who have a family history of alcoholism have a higher risk of developing a drinking problem. Studies show that alcoholism is approximately 50 percent attributable to genetics.

Is there a genetic marker for alcoholism?

Abundant evidence indicates that alcoholism is a complex genetic disease, with variations in a large number of genes affecting risk. Some of these genes have been identified, including two genes of alcohol metabolism, ADH1B and ALDH2, that have the strongest known affects on risk for alcoholism.

What does biological and genetic research indicate about alcoholism?

Abstract. Substantial scientific evidence has accumulated that both genetic and environmental factors predispose the development of alcoholism in certain individuals. Evidence has accumulated to indicate that alcoholism is a heterogeneous entity arising from multiple etiologies.

Is there a genetic relationship between alcoholism and depression?

These analyses found that the “alcoholism or depression” phenotype showed significant evidence for genetic linkage to an area on chromosome 1. This suggests that a gene or genes on chromosome 1 may predispose some people to alcoholism and others to depression (which may be alcohol induced).
