Alzheimer’s Studies Show Genetic Links

The two largest studies of Alzheimer’s disease have led to the discovery of no fewer than five genes that provide intriguing new clues to why it strikes and how it progresses.
Researchers say the studies, which analyzed the genes of more than 50,000 people in the United States and Europe, leave little doubt that the five genes make the disease more likely in the elderly and have something important to reveal about the disease’s process.
“The level of evidence is very, very strong,” said Dr. Michael Boehnke, a professor of biostatistics at the University of Michigan and an outside adviser on the research. The two studies are being published Monday in the journal Nature Genetics.
By themselves, the new genes are not nearly as important a factor as APOE, a gene discovered in 1995 that greatly increases risk for the disease: by 400 percent if a person inherits a copy from one parent, by 1,000 percent if from both parents.
