Alcoholism influenced by hundreds of genes, study finds, Genesis Genetics Brasil

Alcoholism influenced by hundreds of genes, study findsNew research published in PLOS Genetics provides evidence that alcoholism has a genetic influence, after uncovering hundreds of genes that may increase the desire to consume alcohol.Alcohol use disorders remain one of the leading causes of preventable death in the United States, responsible for around 88,000 deathsevery year.According to co-senior study author William M. Muir, Ph.D., professor of genetics at the Indiana University (IU) School of Medicine, and colleagues, it has been challenging for researchers to pinpoint genetic causes of alcoholism in human studies.They note that this is partly down to the array of confounding factors...

Drink-seeking rats provide sobering look into genetics of alcoholism, EurekAlert! Science News

WEST LAFAYETTE, Ind. - Alcohol-craving rats have provided researchers with a detailed look into the complicated genetic underpinnings of alcoholism.By comparing the genomes of rats that drank compulsively with those that abstained, Purdue and Indiana University researchers identified 930 genes associated with alcoholism, indicating that it is a highly complex trait - on par with human height - influenced by many genes and the environment.The study confirmed genes previously identified as being linked to alcoholism and uncovered new genes and neurological pathways, some of which could be promising targets for treatment. But the sheer number of genes that contribute to the trait suggests...

Collaborative Study on the Genetics of Alcoholism - Wikipedia, the free encyclopedia

Collaborative Study on the Genetics of Alcoholism Henri Begleiter, Ph.D. and Theodore Reich, M.D. were founding PI and Co-PI of COGA since its inception. Since 1991, COGA has interviewed more than 17,000 members of more than 2,200 families from around the United States, many of whom have been longitudinally assessed. Family members, including adults, children, and adolescents, have been carefully characterized across a variety of domains, including other alcohol and other substance-related phenotypes, co-occurring disorders (e.g., depression), electrophysiology, key precursor behavioral phenotypes (e.g., conduct disorder), and environmental risk factors (e.g., stress). This has provided us...

The Great Debate: Nature vs. Nurture; Genetics and Abuse

The Great Debate: Nature vs. Nurture, Genetics and AbuseThe Genetic ConundrumFor example, if a gene cannot synthesize a key muscle protein, a person will develop muscular dystrophy. The National Human Genome Research Institute explains that many medical conditions have a genetic component, which means that a person is at risk for developing the condition if it runs in their family, but it does not determine if the person will actually develop the condition. That difference is key to understanding the role of genetics in addiction, and whether addiction is a question of nature versus nurture – or, to put it a better way, how much of addiction is nature versus nurture.The Right Configuration...

Study finds gene network associated with alcoholism, Iowa Now

Study finds gene network associated with alcoholismThere is good evidence from studies of families and twins that genetics plays an important role in the development of alcoholism. However, hundreds of genes likely are involved in this complex disorder, with each variant contributing only a very small effect. Thus, identifying individual risk genes is difficult.Using a new approach that combines genome-wide association studies ( GWAS ) with information about which human proteins interact with one another, researchers from the University of Iowa Carver College of Medicine and Yale University Medical School have identified a group of 39 genes that together are strongly associated with...

Rick Perry: Homosexuality Is Like Alcoholism. He s Wrong, But..., New Republic

Texas Governor Rick Perry has again made headlines for the wrong reasons when, speaking at the Commonwealth Club of California last week, he likened homosexuality to alcoholism. "Whether or not you feel compelled to follow a particular lifestyle or not, you have the ability to decide not to do that," he said. "I may have the genetic coding that I'm inclined to be an alcoholic, but I have the desire not to do that, and I look at the homosexual issue the same way."Gay-rights groups reacted per usual. "Although he may not have the 'genetic coding' to think before he speaks, Rick Perry, M.D. should have a real conversation with actual doctors before voicing his expertise on these issues,” said...

Alcoholism Genetics -- Understanding If You Are at Risk

Alcoholism Genetics? Understanding If You Are at RiskOur genes are responsible for our hair color, health and behavioral characteristics. Passed on by our parents, these genes may also be responsible for addiction. Parents can pass on genetic traits that make their children predisposed to addiction. Nature Versus Nurture: What Role Does Environment Play in an Addiction? While genetics play a role in an addiction, they are only half of the equation. Environmental factors like relationships, work and stress can increase the chances of someone becoming an alcoholic.When these environmental factors are combined with alcoholism genetics, the results can be terrible. Someone who has a...
