Genomic medicine: Sequencing diagnoses disease

DOI: 
10.1038/482009b

In a study that shows both its promise and limitations in the clinic, researchers have used genomic sequencing to diagnose the genetic cause of disease in individual children — but succeeded in only a small proportion of them.

Seeking a gene genie

DOI: 
doi:10.1038/479S10a

Rare gene variants could be key to unlocking the underlying genetics of allergy, now that whole genome sequencing and other technologies have sharpened the focus of epidemiology.

Mapping copy number variation by population-scale genome sequencing

DOI: 
10.1038/nature09708

Harnessing information from whole genome sequencing in 185 individuals, this study generates a high-resolution map of copy number variants. Nucleotide resolution of the map facilitates analysis of structural variant distribution and identification of the mechanisms of their origin. The study provides a resource for sequence-based association studies.

1000 Genomes Project: A map of human genome variation from population-scale sequencing

DOI: 
doi:10.1038/nature09534

The goal of the 1000 Genomes Project is to provide in-depth information on variation in human genome sequences. In the pilot phase reported here, different strategies for genome-wide sequencing, using high-throughput sequencing platforms, were developed and compared. The resulting data set includes more than 95% of the currently accessible variants found in any individual, and can be used to inform association and functional studies.

Genomics: The search for association

DOI: 
10.1038/4671135a

The list of human genetic variations is expanding; but an understanding of how they contribute to disease is still patchy.

Integrating common and rare genetic variation in diverse human populations

DOI: 
10.1038/nature09298

Here, the analysis of 'HapMap 3' is reported — a public data set of genomic variants in human populations. The resource integrates common and rare single nucleotide polymorphisms (SNPs) and copy number polymorphisms (CNPs) from 11 global populations, providing insights into population-specific differences among variants. It also demonstrates the feasibility of imputing newly discovered rare SNPs and CNPs.

Time for the epigenome

DOI: 
10.1038/463587a

The complexity of genetic regulation is one of the great wonders of nature, but it represents a daunting challenge to unravel. The International Human Epigenome Consortium is an appropriate response.

Decoding a national treasure

DOI: 
10.1038/463303a

The giant-panda genome is the first reported de novo assembly of a large mammalian genome achieved using next-generation sequencing methods. The feat reflects a trend towards ever-decreasing genome-sequencing costs.

A genome-wide linkage and association scan reveals novel loci for autism

DOI: 
10.1038/nature08490

Although autism is a highly heritable neurodevelopmental disorder, attempts to identify specific susceptibility genes have thus far met with limited success. Genome-wide association studies using half a million or more markers, particularly those with very large sample sizes achieved through meta-analysis, have shown great success in mapping genes for other complex genetic traits.
