New discovery: Molecular variation in one gene affects the growth of natural populations
For the first time, ecologists have been able to show that molecular variation in one gene may affect the growth of a population in its natural habitat. view more (2006-04-26)
UI Study Reveals Value of Schizophrenia-Related Gene Variation
University of Iowa researchers have learned more about a genetic variation that is a small risk factor for a mild form of schizophrenia, yet also is associated with improved overall survival. view more (2007-02-14)
Variation in the same gene affects rate of parasite infection in both humans and baboons
Researchers at the Duke University Institute for Genome Sciences & Policy have found that variation in the same gene in humans and baboons produces the same kind of disease resistance. view more (2009-06-25)
Longevity gene also protects memory, cognitive function
A gene variation that helps people live into their 90s and beyond also protects their memories and ability to think and learn new information, according to a study published in the December 26, 2006, issue of Neurology, the scientific journal of the American Academy of Neurology. view more (2006-12-26)
Bats add their voice to the FOXP2 story
When it comes to the FOXP2 gene, humans have had most to shout about. Discoveries that mutations in this gene lead to speech defects and that the gene underwent changes around the time language evolved both implicate FOXP2 in the evolution of human language. view more (2007-09-19)
Vaccine to cope with viral diversity in HIV
The ability of HIV-1 to develop high levels of genetic diversity and acquire mutations to escape immune pressures contributes to our difficulties in producing a vaccine. view more (2007-04-27)
New study replicates association between genetic variation and antidepressant treatment response
Pharmacogenetics, the study of genetic variation that influences an individual's response to drugs, is an important and growing focus in all of medical research, including psychiatry. view more (2008-07-16)
Genetic variation increases HIV risk in Africans
A genetic variation which evolved to protect people of African descent against malaria has now been shown to increase their susceptibility to HIV infection by up to 40 per cent, according to new research. Conversely, the same variation also appears to prolong survival of those infected with HIV by approximately two years. view more (2008-07-17)
Throwing the micro switch: MicroRNA may link smoking risk gene to neurobiology of addiction
During the past several years, significant progress has been made in identifying susceptibility genes for nicotine dependence through genetic linkage and association analyses. view more (2009-04-23)
Ecosystem consequences of a single, genetically based plant trait
Climate is often touted as the most important regulator of decomposition and nutrient cycling processes in forest ecosystems, however, in the forthcoming issue of Ecology Letters, Schweitzer and her research team from Northern Arizona University and the University of Wisconsin, USA, demonstrate that plant genes can have strong effects on the... view more...

Gene variations linked to brain aneurysms
Variations in a gene seem to be linked to brain (cerebral) aneurysms, suggests research published ahead of print in the Journal of Neurology Neurosurgery and Psychiatry. view more (2006-04-27)
Scientists Identify Bovine Gene Regulating Milk Production
MTT Agrifood Research Finland and the University of Lie'ge, Belgium, have worked together successfully in locating a gene that regulates total yield and protein and fat content of milk. The scientists found a variation in the growth hormone receptor gene in the bovine chromosome 20. The variation in the receptor gene is associated with a major... view more... (2003-02-20)
Variation in bitter-taste receptor gene increases risk for alcoholism
A team of researchers, led by investigators at Washington University School of Medicine in St. Louis, has found that a gene variant for a bitter-taste receptor on the tongue is associated with an increased risk for alcohol dependence. view more (2006-01-10)
Genetic marker linked to problem behaviors in adults with developmental disabilities
A common variation of the gene involved in regulating serotonin and norepinephrine in the brain may be linked to problem behaviors in adults with developmental and intellectual disabilities, new research indicates. view more (2009-07-22)
Possible genetic predictor for response to lithium augmentation in depressed patients
As in most fields of medicine, psychiatry researchers are working to identify specific types of patients, through their individual genetic variations, that may better benefit from particular drugs or combinations of drugs than other patients. view more (2007-12-07)
NIEHS researchers link gene variation to coronary heart disease
New research at the National Institute of Environmental Health Sciences, part of the National Institutes of Health, found that a common genetic variation makes some people more susceptible to coronary heart disease (CHD). view more (2006-05-12)
New methods offer insight into regulatory DNA
Through the Human Genome Project, the HapMap Project and other efforts, we are beginning to identify genes that are modified in some diseases. More difficult to measure and identify are the regulatory regions in DNA - the 'managers' of genes - that control gene activity and might be important in causing disease. view more (2005-12-16)
Genetic variation linked to age-related macular degeneration
The combination of a certain genetic variation, along with inflammatory factors and smoking, significantly increases the risk of the vision disorder age-related macular degeneration view more (2006-07-19)
The importance of gene regulation for common human disease
A new study published in Nature Genetics on Sunday 16 September 2007 show that common, complex diseases are more likely to be due to genetic variation in regions that control activity of genes, rather than in the regions that specify the protein code. view more (2007-09-17)
GENETIC SUSCEPTIBILITY TO INFERTILITY (p 1336)
In women, unsuccessful attachment and implantation of fertilised eggs (embryos) to the lining of the womb (endometrium), resulting in infertility, could be influenced by variation of a specific gene, conclude authors in a preliminary study described in a research letter in this week's issue of the Lancet. The failure of embryo implantation is... view more... (2001-04-25)
