HapMap 3 points the way forward for human genetics studies New findings show the value of genetic studies across human populations and the value of the latest DNA sequencing technologies to interrogate genetic variation. The results, from the latest phase of the international HapMap Project, are reported in Nature. The researchers' extensive study of genetic variation in multiple populations will form a framework for future genetic studies of variation and disease: their findings highlight...

Researchers with the National Institutes of Health have found susceptibility to Behcet's disease, a painful, inflammatory condition, to be associated with genes involved in the body's immune response. Although the Greek physician Hippocrates described Behcet's disease (pronounced BET'-chet's), more than 2,000 years ago, the condition existed in relative obscurity until the early 20th century. Named for the Turkish physician who first classified it in 1937, Behcet's disease is found almost...

Genetic variant detected by genome-wide association found to increase expression of oncogene A genetic variant implicated in several cancers by genome-wide association studies (GWAS) has been found to drive increased expression of a known oncogene in the prostate. The study, published July 13th in Genome Research, showcases a new protocol for studying the activity of cancer-risk variants suggested by GWAS studies. The results also underscore the dramatic consequences of small genetic changes...

Boston University researchers have discovered a genetic sequence that predicts with more accuracy than ever before whether a person will live to the age of 100 -- even if they have other genes associated with disease. The scientists studied over 1,055 centenarians to develop a system of genetic analysis that predicts with 77-percent accuracy whether a person has a strong chance of "exceptional longevity".  The predictions involve identifying the presence of 150 genetic variants known as...

New study at University of Leicester aims to pave way for treatments New research at the University of Leicester will use the latest genetic techniques to examine DNA from over 20,000 patients with heart disease. The study will help to identify new genes and molecules responsible for Coronary Artery Disease (CAD). This, in turn may help to develop new diagnostic and treatment strategies. The project is being undertaken by postgraduate researcher Paraskevi Christofidou, of the Department of...

Three genes that have barely been studied to date have now provided fresh knowledge about patients with suicidal backgrounds. This is the result of a study by a team of Spanish researchers at Mount Sinai Hospital and Columbia University in the City of New York (United States), which found that several mutations are involved. This finding could help to develop future genetic tests to identify predisposition to suicide, without ignoring the importance of social and cultural factors. "There is...

Although congenital heart disease represents the most common major birth defect, scientists have not previously identified the genes that give rise to it. Now genetics and cardiology researchers, two of them brothers, have discovered a genetic variant on chromosome 5 that strongly raises the risk of congenital heart disease. "This gene, ISL1, plays a key role in regulating early cardiac development, so there is a compelling biological reason for investigating it as a genetic risk factor for...

Most people associate serotonin with brain neurology, but over 95 percent of the body's serotonin occurs in the gastrointestinal tract, which has a complex neuronal circuit that has been called "the second brain" of the body. Now a Mayo Clinic research team has identified a number of genetic variants in serotonin genes that impact irritable bowel syndrome or IBS. The findings were presented today at Digestive Disease Week 2010 in New Orleans. IBS is one of the most common chronic disorders of...

-- New Approach Also Specifies Results for Individual Patients -- PHILADELPHIA, April 29 /PRNewswire-USNewswire/ -- In findings that may speed the search for disease-causing genes, a new study challenges the prevailing view that common diseases are usually caused by common gene variants (mutations). Instead, say genetics researchers, the culprits may be numerous rare variants, located in DNA sequences farther away from the original "hot spots" than scientists have been accustomed to look....
