摘要

Genome sequencing may finally be living up to its promise of pinpointing genetic mutations that bear on treatment for individual patients. But the breakthroughs are not coming from the DNA analysis of common diseases with complex genetic origins, which has been the obsession of genomics for nearly the past decade. Instead, many genome scientists are turning back to study rare disorders that are traceable to defects in single genes, and whose causes have remained a mystery.rnThe change is partly a result of frustration with the disappointing results of genome-wide association studies (GWAS). Rather than sequencing whole genomes, GWAS studies examine a subset of DNA variants in thousands of unrelated people with common diseases. Now, however, sequencing costs are dropping, and whole genome sequences can quickly provide in-depth information about individuals, enabling scientists to locate genetic mutations that underlie rare diseases by sequencing a handful of people.
