Massive sequencing database helps interpret mutations’ role

by  /  23 October 2014

Researchers have analyzed more than 90,000 exomes — the protein-coding regions of the genome — the largest such set yet, they announced Monday at the American Society of Human Genetics Annual Meeting in San Diego. The resource gives scientists an invaluable tool to probe the significance of specific mutations.
