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 ...

Researchers have found statistically significant links between a gene tied to schizophrenia risk and poorer cognitive ...

Researchers report that they have identified genetic variants that determine the shape of human teeth, including a gene inherited from Neanderthals. The scientists published their paper “PITX2 ...

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 ...

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 ...

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 ...

Many genetic mutations have been found to be associated with a person’s risk of developing Parkinson’s disease. Yet for most of these variants, the mechanism through which they act remains unclear.

Your genes can increase the risk of depression, especially if you have a close relative with it. Depression is not caused by a single gene, but by variations in many genes. Twin studies show that ...
