Variations in a number of different genes and environmental factors affect an individual's risk for osteoporosis.   view more (2006-02-21)

Dardarina, the Basque gene for Parkinson's
Research began when doctors discovered that various members of the same family had Parkinson's. There are many kinds of Parkinson's and some are hereditary. Now, a group of scientists have identified the gene which produces the hereditary Park8 variant of Parkinson's in four Basque families and... view more (2004-11-04)

Written by the investigator himself/herself, this press release does not necessarily reflect the opinion of the European Society of Cardiology ESC Congress 2003: Some people are more susceptible to... view more (2003-09-01)

Genetic risk factor for common childhood respiratory infection identified
The severity of the common childhood infection, bronchiolitis, may be genetically determined, shows research in Thorax. Bronchiolitis is a respiratory infection which affects nearly all children by their second year. Occurring in winter epidemics, in most cases it is caused by respiratory syncytial... view more (2000-11-16)

BSE link to new variant CJD is open to question
The link between the bovine spongiform encephalopathy (BSE) prion and new variant Creutzfeldt-Jakob disease is open to question, argues George Venters, Consultant in Public Health Medicine, in this week's BMJ. He applied standard criteria - used to establish links between cause and disease - to... view more (2001-10-09)

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)

Some smokers have genetic predisposition to develop COPD, research shows
Some people have a genetic variation that makes them more susceptible to chronic obstructive pulmonary disease (COPD) if they smoke tobacco, according to new research from Wake Forest University School of Medicine and colleagues.   view more (2007-07-12)

Breakthrough in national diseases: Common factor behind myocardial infarction, rheumatism and MS
A common gene variant has been identified as the risk factor behind a number of common diseases by research scientists at Karolinska Institutet and the Centre for Molecular Medicine (CMM), Stockholm, Sweden. Up to a quarter of the population could be affected.   view more (2005-04-08)

Claiming diagnostic tests for diabetes genes is misleading, say experts
Claims that the discovery of a gene could help prevent diabetes may raise unrealistic expectations, warn doctors in this week's BMJ.   view more (2006-09-08)

New genetic research into nicotine addiction shows promise for personalized treatment
Whether a smoking-cessation drug will enable you to quit smoking may depend on your genes, according to new genotyping research from the Centre for Addiction and Mental Health (CAMH).   view more (2007-09-18)

Salmonella survives better in stomach due to altered DNA
Since 1995 there has been a considerable increase in the number of infections with a specific type of Salmonella bacteria transmitted via food. This type, Salmonella serovar Typhimurium DT104, is resistant to at least five different antibiotics.   view more (2007-01-31)

Gene link to increased risk of coronary heart disease, found by scientists.
The risk of contracting coronary heart disease increases three fold among smoking males who carry a particular gene variant, scientists will reveal at a press briefing next week. Professor Steve Humphries, British Heart Foundation Professor of Cardiovascular Genetics at University College London... view more (2001-07-06)

International Surveillance System Suggests 2002 Gastroenteritis Outbreaks Arose From New Variant Norovirus (Pp 671, 682)
The increase in severe outbreaks of gastroenteritis in 2002-including the notorious outbreaks on US cruise ships-were probably a result of a new variant of norovirus, conclude authors of a study in this week's issue of THE LANCET. Ben Lopman from the UK Health Protection Agency and European... view more (2004-02-25)

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)

Scientists identify gene that influences alcohol consumption
A variant of a gene involved in communication among brain cells has a direct influence on alcohol consumption in mice, according to a new study by scientists supported by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health (NIH), and the U.S.... view more (2007-12-06)
