Fifth of people have gene that protects against Alzheimer's and could one day lead to vaccine, study says

Fifth of people have gene that protects against Alzheimer's and could one day lead to vaccine, study says One in five people carry a genetic variant that appears to protect against Alzheimer’s and Parkinson’s, a study suggests.

Analysis of medical and genetic data from hundreds of thousands of people found that having this variant, called DR4, reduced people’s chances of developing either condition by more than 10 per cent on average.

Experts say the discovery may one day lead to a vaccine that could slow or stall the progression of these two common conditions. The Daily Mail
