PHOENIX, June 6, 2007--A study comparing more genetic markers in the DNA of people with and without Alzheimer’s disease than ever before has enabled researchers to identify a common gene that appears to increase a person’s risk for developing Alzheimer’s disease. The finding, announced today by researchers at the Translational Genomics Research Institute (TGen), Banner Alzheimer’s Institute, Kronos Science Laboratory and their collaborative partners, suggests that the gene - called GAB2 - modifies an individual’s risk when associated with other genes, including APOE4. The study results appear in the June 7 issue of the prestigious peer-reviewed journal, Neuron.
