Panel of 11 genes predicts alcoholism risk, gives new insights into biology of the disease : Newscenter : School of Medicine

Panel of 11 genes predicts alcoholism risk, gives new insights into biology of the diseaseINDIANAPOLIS -- A group of 11 genes can successfully predict whether an individual is at increased risk of alcoholism, a research team from the United States and Germany reported Tuesday."This powerful panel of just 11 genes successfully identified who has problems with alcohol abuse and who does not in tests in three patient populations on two continents, in two ethnicities and in both genders," said Alexander B. Niculescu III, M.D., Ph.D., principal investigator and associate professor of psychiatry and medical neuroscience at the Indiana University School of Medicine.The panel of genes is highly...

Can a Genetic Test Predict Risk for Alcoholism?

Is a Genetic Test for Alcoholism Too Good to Be True?The authors of a study published in May 2014 in the journal Translational Psychiatry are optimistic that they have identified a number of gene variations that could be used to predict who is at greatest risk for alcoholism.The researchers, led by a team at the Indiana University School of Medicine, identified a group of 11 genes that seem to have the ability to distinguish people who have problems with alcohol abuse from people who do not. The team speculated that the results could eventually be used to test people at an early age for susceptibility to alcoholism and help save many of them from falling victim to this disease....

Alcoholism May Be Rooted in Your DNA, Future of You, KQED Future of You, KQED Science

If you’re one of those people who likes drinking more than everyone else, you might have an excuse: You have lazy genes.Well, at least one lazy gene.A new study  out of the University of Valencia in Spain confirms something about Spaniards that scientists have known about Asians for a long time: People with a “lazy” version of the ADH1B gene find alcohol more enjoyable than people with a more efficient one.People of Asian descent who enjoy alcohol more because of their genes are also more likely to suffer from alcoholism.  A recent study confirmed this in British and Irish people, as well.The finding could  help counselors tailor treatments for people with alcoholism.There are a couple of...

Alcohol Abuse Linked to Newly Identified Gene Network, UT News, The University of Texas at Austin

AUSTIN, Texas  Researchers at The University of Texas at Austin have identified a network of genes that appear to work together in determining alcohol dependence. The findings, which could lead to future treatments and therapies for alcoholics and possibly help doctors screen for alcoholism, are being published this week in the journal Molecular Psychiatry.By comparing patterns of genetic code from the brain tissue of alcoholics and nonalcoholics, the researchers discovered a particular set of genes co-expressed together in the individuals who had consumed the most alcohol. Specifically, certain sets of genes were strongly linked as networks in alcoholics, but not in nonalcoholics."This...

The Genetics of Alcoholism

The Genetics of AlcoholismFor the last 25 years, the National Institute on Alcohol Abuse and Alcoholism (NIAA) has funded a comprehensive research effort to identify the link between genes and alcoholism, known as the Collaborative Studies on the Genetics of Alcoholism (COGA).Though considerable time, money and effort has been has been expended on this effort, no single gene has been identified as distinctly linked to alcoholism, and no gene-based therapy had proven effective across a wide enough population to be considered a breakthrough. On its website, the NIAA states “Research shows that genes are responsible for about half of the risk for alcoholism.” Genes Linked to AlcoholismA host...

A Gene May Discourage Drinkers from Becoming Alcoholics

A Gene May Discourage Drinkers from Becoming AlcoholicsResearchers have identified a gene that may protect some people from alcoholism, while making them lightweights at the bar.It was already known that people who become inebriated easily when they begin their drinking careers are less likely to become alcoholics in the long run. Now new genetic research has zeroed in on the gene indirectly responsible for the protective effect for 10 to 20 percent of the population.This gene, called CYP2E1, codes for an enzyme that breaks down ethanol...

Genetic Factors in Addiction and Alcoholism

Genetic Factors in Addiction and AlcoholismIf you have family members who are alcoholics or drug addicts, unfortunately, your family may be on the losing side of the genetic lottery where addiction is concerned. Studies have repeatedly verified that genetics is at least fifty per cent responsible for a person’s susceptibility to alcoholism or drug addiction. This does not a child of an alcoholic or drug addict will necessarily become addicted. It does mean that this child has a higher risk of becoming an alcoholic or drug addict.Genetic Factors in Addiction and AlcoholismAlcoholism and drug addiction start out as behaviors that are influenced by both genetic and environmental factors. A...

Genetic Trait Linked to Alcoholism

THURSDAY, Nov. 20 (HealthDay News) -- Variations in the genetic makeup of alcoholics may affect how much they drink, a new study suggests.And the key might be the brain's control of serotonin, a mood-influencing neurological chemical.The research could potentially help doctors understand who might be at highest risk of becoming an alcoholic, and then treat that person, said study co-author Ming D. Li, head of neurobiology at the University of Virginia.Li added that the research is unique, because it shows that a single gene variation is connected to a kind of behavior -- alcoholism.The genetic blueprint that people inherit from their parents accounts for an estimated 40 percent to 50...
