Five common genetic variations linked to metabolic syndrome and HDL cholesterol levels

Nutrition researchers at Washington University School of Medicine in St. Louis have identified five common genetic variations that increase the risk of metabolic syndrome, a group of factors linked to heart disease and diabetes. Another variant they found appeared to protect against the condition.

deCODE discovers novel genetic links between pigmentation traits and risk of skin cancer

In two papers published today, deCODE scientists and academic colleagues from Europe and the U.S. expand upon the company's recent findings in the genetics of pigmentation traits in people of European descent, and demonstrate that certain of these common variants also confer risk of two types of skin cancer.

Discovery of ten new genes related to human growth

Scientists are beginning to unravel the question why people distinctly vary in size. In cooperation with scientists of the HelmholtzZentrum Munchen, an international genome-wide study has discovered ten new genes that influence body height and thus provides new insights into biological pathways that are important for human growth.

Discovery of DNA variations in chromosome 6 that gives rise to neuroblastoma

Using advanced gene-hunting technology, an international team of researchers has for the first time identified a chromosome region that is the source of genetic events that give rise to neuroblastoma, an often fatal childhood cancer.

Whole-organ genomic survey depicts journey from normal to malignant cell

Whole-organ maps that superimpose genetic information over the terrain of cancerous bladders chart the molecular journey from normal cell to invasive cancer, an international research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports online at the journal Laboratory Investigation.

Scientists discover 4th major set of common genetic variants linked to risk of estrogen receptor-positive breast cancer

Scientists from deCODE genetics report the discovery of two common single-letter variants (SNPs) on chromosome 5 of the human genome that are associated with risk of estrogen receptor-positive (ER+) breast cancer.

Special needs plans seek to avoid moratorium by providing more data to congress

Officials from special needs plan providers said Thursday at a Capitol Hill briefing that they will provide Congress with more data on the services the plans provide to beneficiaries with severe chronic medical conditions, CQ HealthBeat reports.

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.
