The specific DNA sequence present at a particular chromosome location.
Individuals with alterations in ABCB1 and ABCC1, two genes thought to be involved in getting rid of inhaled toxins from the lungs, may have an increased risk of developing lung cancer, according to a new study published in the journal Cancer. The research, carried out by Chinese...
A gene variant previously thought to increase the risk of migraine in women has been shown, in fact, to have a mildly protective effect, according to a new study published in the journal Neurology. However, the study also shows that if women go on to develop migraines...
Canadian researchers, based at University of Toronto, have discovered a genetic variation which may help to explain why some people have a sweet tooth, causing them to consume more sugary foods and drinks in their diet. The findings, published online last week in the journal Physiological Genomics...
In the first move of its kind, the US Food and Drug Administration (FDA) - the agency responsible for regulating food, drugs and biological medical products - has recommended a genetic test prior to the prescription of a drug, Warfarin, in order to gauge potential patient response. Warfarin, sold...
Neuroscientists in Switzerland have identified a gene that influences the recall of emotionally charged memories. Dominique de Quervain, and colleagues, at the University of Zurich published a study in Nature Neuroscience last week reporting that subjects with the gene variant ADRA2B performed better on recall tests for...
Consumers' ability to obtain laboratory test services directly and without a medical order is increasing. Is this a good thing? Direct to consumer, otherwise known as direct access, clinical testing has been permitted for many years in some, but not in all states within the US. This disparity suggests that...
Women smokers with a particular genetic variation are more likely to benefit from nicotine patches when trying to quit than others, a new UK study suggests. Researchers at the University of Oxford studied 445 women and 307 men who had been heavy smokers, who were given either nicotine or control...
The 50th anniversary of the discovery of the structure of DNA presents a golden opportunity to take stock of what impact this and subsequent discoveries in molecular genetics have had and what it promises for the future of human health and happiness. Genetics is now big business. Worldwide anniversary celebrations...
