Rapidly testing hundreds of thousands of DNA sequences, scientists identified specific genetic variations contributing to blood pressure, cholesterol, and blood sugar.

NEW ORLEANS – The accuracy of prostate-specific antigen (PSA) screening for prostate cancer could be improved by accounting for genetic factors that cause changes in PSA levels that are not associated ...

Genetic variants that determine the shape of your teeth -- including a gene inherited from Neanderthals -- have been identified by a team of researchers. Genetic variants that determine the shape of ...

The human genome is organised in 46 chromosomes, where all but the x and y chromosomes in men are present in two copies. This means that a person with a faulty gene on one chromosome most often has a ...

For more than a century, Mendelian genetics has shaped how we think about inheritance: one gene, one trait. It is a model that still echoes through textbooks—and one that is increasingly reaching its ...

Freckles are often caused by variations in a particular gene that affects melanin. They are common and usually harmless. If you have concerns about any marks on your skin, consult a dermatologist for ...

Genes are by no means a crystal ball, but they can be used to forecast susceptibility to a variety of conditions, from cancers and heart disease to chronic inflammatory conditions. As such, they can ...
