New Alzheimer’s Gene Found

Gene May Explain 5% of Inherited Alzheimer's Disease Cases

Genome-Wide Technique Aids Finding of New Alzheimer's Gene continued...

Several other research teams have reported homing in on gene variants involved in Alzheimer's over the years, he says, but the findings often could not be duplicated.

"It's also always nice if the genetics make sense with the biology of the disease," as is the case here, Peterson tells WebMD.

Having genes that can help pinpoint who will develop Alzheimer’s disease before symptoms develop will be even more beneficial once drugs to prevent or slow the course of the disorder become available, he says.

Few people have opted to be tested for the ApoE gene, even though testing is available, according to the Alzheimer's Association.

The World Health Organization estimates that there are 18 million people worldwide with Alzheimer’s disease, a figure projected to nearly double to 34 million by 2025. There are more than 5 million Americans living with Alzheimer’s disease.

The study was supported by the National Institutes of Health and the National Institute on Aging.
