In one of the first studies to link molecular genetic variants to adolescent delinquency, sociological research published in the August issue of the American Sociological Review identifies three genetic predictors—of serious and violent delinquency—that gain predictive precision when considered together with social influences, such as family, friends and school processes.

Using new techniques for rapidly scanning the human genome, researchers have associated levels of cholesterol and triglycerides, two fats in the blood, to 18 genetic variants, six of which represent new DNA regions never before associated with the traits.

In studies involving more than 35,000 people and a survey across the entire human genome, an international team supported in part by the National Institutes of Health (NIH) has found evidence that common genetic variants recently linked to osteoarthritis may also play a minor role in human height.

Environmental and genetic factors influence a person’s blood fat, or lipid levels, important risk factors for coronary artery disease (CAD). While there is some understanding of the environmental contribution, the role of genetics has been less defined.

Common genetic variants linked to arthritis may also play a role in human height, a new study shows.

Why the same sweaty man smells pleasant to one person and repellant to another comes down to the smeller’s genes.

A genetic variant present in nearly half of Americans of European ancestry is linked to greater effectiveness of the smoking cessation medication bupropion (Zyban), according to research by scientists supported by the National Institute on Drug Abuse (NIDA) and the National Cancer Institute (NCI), part of the National Institutes of Health (NIH).
