New gene linked to Alzheimer's risk

Researchers from the University of Miami have identified a new gene associated with an increased risk of developing Alzheimer's disease. In a study of 5,376 people, 2,269 of whom had Alzheimer's disease, the researchers compared a stretch of genes to see if certain variations were more common in the people with Alzheimer's. They found that a gene called MTHFD1L on chromosome six was associated with a doubling in the risk of developing late-onset Alzheimer's. The gene is known to be involved in influencing the body's levels of a substance called homocysteine, high levels of which are known to be a strong risk factor for late-onset Alzheimer's diseases.
