Genetic irregularities linked to higher risk of COPD among smokers
Scientists at Duke University Medical Center have discovered two genetic markers that appear to put some smokers at significantly higher risk of developing chronic obstructive pulmonary disease (COPD). view more (2009-03-20)
Genetic marker linked to aggressive prostate cancer
Northwestern University researchers have discovered that a recently identified genetic marker for prostate cancer is linked to a highly aggressive form of the disease. view more (2007-05-21)
NIH unprecedented genetic study may help identify people most at risk for alcoholism
Researchers at the Molecular Neurobiology Branch of the National Institute on Drug Abuse (NIDA), National Institutes of Health, have completed the most comprehensive scan of the human genome to date linked to the ongoing efforts to identify people most at risk for developing alcoholism. view more (2006-08-28)
The Peopling of the Americas: Genetic ancestry influences health
At one time or another most of us wonder where we came from, where our parents or grandparents and their parents came from. view more (2009-08-17)
Genetic variants of USF1 are associated with the increased risk for cardiovascular disease
Cardiovascular diseases (CVD) are major contributors to morbidity and mortality worldwide. Several interacting environmental, biochemical, and genetic risk factors can increase disease susceptibility. view more (2008-04-08)
New method to analyse the Major Histocompatibility Complex (MHC) of the human genome
Scientists at Fred Hutchinson Cancer Research Center have developed a new method for analyzing the Major Histocompatibility Complex (MHC) of the human genome. view more (2006-04-24)
The aye-ayes have it: The preservation of color vision in a creature of the night
A quest to gain a more complete picture of color vision evolution has led Biodesign Institute researcher Brian Verrelli to an up-close, genetic encounter with one of the world's most rare and bizarre-looking primates. view more (2007-09-05)
People are unlikely to withdraw consent for genetic research
People are unlikely to withdraw consent for genetic research even when samples were taken many years ago, research in this week's BMJ suggests. In 1990 1583 randomly selected people in Sweden donated blood to a World Health Organisation project researching cardiovascular disorders and diabetes. Eleven years later, doctors sought their consent for... view more... (2002-09-18)
Predictive genetic tests range from highly useful to potentially harmful
Predictive genetic testing has the potential to save lives through targeted surveillance and preventive measures, but a paper in this week's BMJ reports that most genetic tests carry a degree of uncertainty, which limits their usefulness and, in some cases, can even be harmful to patients. For some diseases, predictive genetic testing is highly... view more... (2001-04-24)
Researchers identify genes associated with onset age of Parkinson's disease
Researchers from Boston University School of Medicine (BUSM) have identified genes which may influence the onset age of Parkinson's Disease (PD). view more (2009-10-08)
Gene associated with pair-bonding in animals has similar effects in human males
Variation in the gene for one of the receptors for the hormone vasopressin appears to be associated with how human males bond with their partners, according to an international team of researchers. view more (2008-09-04)
Studies identify DNA regions linked to nicotine dependence
Americans are bombarded with antismoking messages, yet at least 65 million of us continue to light up. Genetic factors play an important role in this continuing addiction to cigarettes, suggest scientists at Washington University School of Medicine in St. Louis. view more (2007-02-15)
Obesity genes revealed
A study of 228 women has revealed genetic variants responsible for body shape. Based on work in the fruit fly Drosophila melanogaster, research published today in the open access journal BMC Genetics identifies natural variation in the human LAMA5 gene as a key determinant of weight. view more (2008-08-11)
Mother's genes determine sperm design
A new study at the University of Sheffield, published today in Nature, has found that the size and shape of a zebra finch's sperm are genetically passed down from the mother, a fact that may also be true in humans. The paper Genetic effects on sperm design in the zebra finch, also suggests that when sperm operate in a non-competitive environment... view more... (2005-03-15)
Genetic variation affects smoking cessation treatment
Mark Twain boasted that it was easy to quit smoking because he did it every day. We now may have the beginnings of understanding why some people find it so difficult to stop smoking even when they are in treatment for this problem. view more (2007-09-21)
Genetic contributions to human brain morphology and intelligence
While showing an impressive growth prenatally, the human brain is not completed at birth. There is considerable brain growth during childhood with dynamic changes taking place in the human brain throughout life, probably for adaptation to our environments. view more (2007-10-17)
Smoking and the Risk of Rheumatoid Arthritis
Study Shows Significantly Higher Risk for the Disease Among Current Smokers with a Classic Genetic Risk Factor view more (2004-10-07)
Environmental effects on genetic adaptation and population dynamics
It seems intuitive that genes are affected by selection as a result of environment. In fact there is little evidence thus far that such genetic effects impact year-to-year population dynamics. view more (2006-04-25)
Researchers discover baldness gene: 1 in 7 men at risk
Researchers at McGill University, King's College London and GlaxoSmithKline Inc. have identified two genetic variants in caucasians that together produce an astounding sevenfold increase the risk of male pattern baldness. view more (2008-10-13)
Genetic variation found that predicts response to heart failure medication
Researchers at the University of Maryland School of Medicine in Baltimore and the University of Colorado School of Medicine in Denver have identified a common genetic variation that could help determine whether a person with heart failure would benefit from beta-blockers, a class of drugs used to treat chronic heart failure. view more (2006-07-11)
