Is there a gene 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 are the most rare genetic diseases?

What are rare genetic conditions?
Progeria is a rare genetic condition affecting around 1 in 8000,000 live births. It is a genetic condition caused as a result of a new mutation in the gene and is generally not inherited. It causes rapid aging in children, and as a result, individuals affected by this disease die by the age of 13 to 20.
