Metabolic genes tied to inflammatory predictor of heart disease and stroke risk

Two new studies provide evidence that differences in people's blood levels of C reactive protein (CRP) stem in part from natural variation in known metabolic genes. The researchers report their findings in the May American Journal of Human Genetics, a publication of Cell Press.

What we eat and drink affects our risk of cancer

A healthy diet and lifestyle protect against a wide range of diseases, and new research presented at the American Association for Cancer Research 2008 Annual Meeting, April 12-16, shows that cancer is no exception.

Discovery of new genetic links to psoriasis

In the first comprehensive study of the genetic basis of psoriasis, researchers at Washington University School of Medicine in St. Louis have discovered seven new sites of common DNA variation that increase the risk of the troublesome skin condition.

Answer to troublesome question of why some genetic assoc. studies have failed replication attempts

A team of researchers from Harvard School of Public Health (HSPH), Brigham and Women's Hospital (BWH), and elsewhere have described a possible reason why some studies have been unable to replicate associations between genes and traits -- namely that the strength of a gene/trait association might vary with age and that current study designs typically fail to take that into account.

Genetic variations raise lung cancer risk for smokers and ex-smokers

Two common inherited genetic variations are associated with increased risk of lung cancer for smokers and former smokers, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports April 2 in the online edition of Nature Genetics.

Cholesterol-associated gene variants can predict cardiovascular events

A study appearing in this week's New England Journal of Medicine confirms that a combination of gene variants previously associated with cholesterol levels does reflect patients' cholesterol levels and can signify increased risk of heart attack, stroke or sudden cardiac death.

Body mass index higher among bariatric surgery patients with 2 genetic variations

The combination of two obesity-related genetic variations may be associated with an increased body mass index (BMI) among severely obese patients undergoing bariatric weight loss surgery, according to a report in the March issue of Archives of Surgery.

Genomics researchers fine-tune marker for common obesity gene

Genomics researchers, seeking to replicate another group's discovery of an important gene associated with obesity, have further refined the signal to a particular variant in DNA that may be more helpful in identifying this gene's role in obesity in various human populations worldwide.

Gene markers located for hereditary prostate cancer

Researchers at the Johns Hopkins Brady Urological Institute, Wake Forest University and the Karolinska Institute in Sweden have identified an array of gene markers for hereditary prostate cancer that, along with family history for the disease, appear to raise risk to more than nine times that of men without such markers.

Genetic differences may explain response to multiple sclerosis treatment

By comparing the DNA of patients with multiple sclerosis whose symptoms are reduced by interferon beta therapy to the DNA of those who continue to experience relapses, researchers may have identified important genetic differences between the two, according to an article posted online that will appear in the March 2008 print issue of Archives of Neurology.
