Whole Genome Sequencing Reveals 13 New Gene Variants in Alzheimer s Disease

In a genome-wide association study (GWAS), the genomes of many individuals are scanned in search of common gene variants that occur more frequently in people who have a given disease, such as Alzheimer’s disease (AD). However, common Alzheimer’s-associated gene variants have accounted for less than half of the heritability of AD. A standard GWAS misses the rare gene variants (those occurring in less than 1% of the population). Now researchers at Massachusetts General Hospital (MGH), the Harvard T. H. Chan School of Public Health, and Beth Israel Deaconess Medical Center, report they have used whole genome sequencing (WGS) to discover rare genomic variants associated with AD, and have identified 13 variants.

Scientists find 13 rare Alzheimer s gene variants

A new study highlights findings from sequencing more than 2,000 people’s genomes. By Story at a glance The genes associated with the disease affect the brain’s function and development. Researchers have identified rare gene variants associated with Alzheimer’s disease. Researchers have identified 13 variants of genes connected to Alzheimer’s disease that are new to scientists. In a study published in Alzheimer s & Dementia: The Journal of the Alzheimer s Association, the researchers report how they sequenced whole genomes of people in more than 600 families with individuals who have been diagnosed with Alzheimer’s and searched for rare versions of genes.

First-of-its-kind study identifies 13 new Alzheimer s disease genes

First-of-its-kind study identifies 13 new Alzheimer’s disease genes In the first study to use whole genome sequencing (WGS) to discover rare genomic variants associated with Alzheimer s disease (AD), researchers have identified 13 such variants (or mutations). In another novel finding, this study establishes new genetic links between AD and the function of synapses, which are the junctions that transmit information between neurons, and neuroplasticity, or the ability of neurons to reorganize the brain s neural network. These discoveries could help guide development of new therapies for this devastating neurological condition. Researchers at Massachusetts General Hospital (MGH), the Harvard T. H. Chan School of Public Health, and Beth Israel Deaconess Medical Center report these findings in
