Q: I have a relative who is an alcoholic. Is there a hereditary link and can
I be tested to see if I am at greater risk for alcoholism?
A:. By studying the incidence of alcoholism in families, doctors have firmly
established a genetic link to the risk of having drinking problems. However,
currently there is no way to tell if a specific person in a family is at
risk.
"Children of alcoholics are intensely concerned about their own risk
for alcoholism and the possibility they will pass this along to their
children," says David Crabb.M.D., a specialist in alcoholism at the Indiana
University Medical Center. "We can't yet test someone and say they have a
higher or lower than average risk. Moreover, only about half of the risk of
alcoholism is genetically linked. Environmental factors are still important
and effect everyone."
Further complicating the issue is the feeling among researchers that
several genes, although probably less than ten, are involved. This means that
identification of all the genes, what they do in the body and how they
interact may be needed before the genetic link of alcoholism can be fully
explained.
According to Dr. Crabb there are three main thrusts to research into
the genetic component of the disease. First is identifying those at genetic
risk so counseling can begin early and possibly avoid problem drinking
entirely. The second track will be to find drugs or other methods to
interfere with the actions of the bad genes. Finally, and a long way down the
road, is to find ways to actually change the gene so it functions
differently.
"We are a major participant in a long-term study in this area," notes
Dr. Crabb. "Large numbers of families with many alcoholics have been
identified. Now we are trying to find gene markers that are inherited along
with the tendency toward alcoholism."
