A WEBSITE has been relaunched in a bid to take genetics to a wider audience and unravel the mysteries of DNA.

Relaunched last week to coincide with Association for Science Education's Annual Conference, yourgenome.org has been developed by public engagement professionals at the Wellcome Genome Campus at Hinxton.

The site aims to provide accessible, entertaining and thought-provoking guides to an area of science that is revolutionising diagnosis and treatment.

Genomics has been catapulted into the public conciousness in recent months, with the Government having pledged to understand the genomes of 100,000 people. In December, website 23andMe launched a UK version, enabling people in this country to to have their DNA screened for genes associated heridetary conditions such as cystic fibrosis or sickle cell anaemia. Regular readers of Ideas will also know that Cambridge is home to a number of firms specialising in genomics, such as start-up GeneAdviser which is aiming to provide accurate testing for patients with rare genetic diseases.

"Genomics is constantly in the news but, for many, DNA and its role in our biology is still something of a mystery," says Dr Julia Willingale-Theune, manager of public engagement at the Wellcome Genome Campus. "With yourgenome.org, we want to share what scientists know about the genome already and what they are trying to find out, helping everyone to understand and engage with a topic that's likely to have a huge impact on their future health."

The website provides key facts about genomics and bioinformatics with the help of videos and 3D animations. It also features posts by experts looking at advances in research and applications in healthcare. There are also debates that give readers a balanced view of the more controversial aspects of genomics, such as data security, animal research and gene therapy.

Content on the website is driven by an editorial board comprised of expert researchers and specialists in science education and communication from the Wellcome Genome Campus and beyond. This editorial board will ensure that the website remains up-to-date, relevant and accurate.

The Wellcome Genome Campus is home to the Wellcome Trust Sanger Institute, which made the greatest single contribution to the Human Genome Project in 2003 and has remained at the forefront of genetic research ever since. It is also home to the European Bioinformatics Institute, which goes by the catchy acronym of EMBL-EBI. This is a global leader in the storage, analysis and dissemination of large biological datasets, and helps scientists realise the potential of 'big data', enhancing their ability to exploit complex information to make discoveries that benefit mankind. Experts from both institutes have contributed to the site.

"During our lifetimes, the way we experience healthcare will change; in the next decade many aspects of care, from diagnosis to medication, and many lifestyle choices will depend on the information encoded in our genome," said Jon Kudlick, director of membership, marketing and communications at the Society of Biology.

Simons Foundation awards up to $1 million to UC Santa Cruz Genomics Institute to develop a comprehensive Human Genome Variation Map for scientific and medical research

Researchers at the UC Santa Cruz Genomics Institute have received a grant for up to $1 million from the Simons Foundation to develop a comprehensive map of human genetic variation. The Human Genome Variation Map will be a critical new resource for both medical research and basic research in the life sciences.

The one-year pilot project aims to overcome the limitations of the current model for analyzing human genome data, which is based on the use of a single reference sequence for the human genome. Essentially, all novel sequencing data is analyzed by mapping new genome sequences to this one reference set of 24 human chromosomes to identify variants. But this approach leads to biases and mapping ambiguities, and some variants simply cannot be described with respect to the reference genome, according to David Haussler, professor of biomolecular engineering and director of the Genomics Institute at UC Santa Cruz.

"One exemplary human genome cannot represent humanity as a whole, and the scientific community has not been able to agree on a single precise method to refer to and represent human genome variants. There is a great deal we still don't know about human genetic variation because of these problems," said Haussler, who will lead the project with co-investigator Benedict Paten, a research scientist at the Genomics Institute.

According to Paten, the proliferation of different genomic databases has resulted in hundreds of specialized coordinate systems and nomenclatures for describing human genetic variation. UC Santa Cruz genomics researchers are intimately familiar with this "Tower of Babel" of databases through their work to display data from all these sources on the widely used UCSC Genome Browser. Launched in July 2000 shortly after UC Santa Cruz posted the first working draft of the human genome sequence on the Internet, the browser now serves 130,000 researchers around the world and gets more than 1 million web page requests per day.

"For now, all our browser staff can do is to serve the data from these disparate sources in their native, mutually incompatible formats," Paten said. "This lack of comprehensive integration, coupled with the over-simplicity of the reference model, seriously impedes progress in the science of genomics and its use in medicine."

Recently, with funding from the Simons Foundation, researchers David Reich and Nick Patterson at the Broad Institute of MIT and Harvard have amassed more than 300 complete human genome sequences representing a range of ethnicities. Haussler and Paten plan to use this set of human genomes, which they say is deeper and more completely organized than any prior human data set, to build a new graph-based human reference genome structure.

"This unique data set of genome diversity gives us an opportunity to define a comprehensive reference genome structure that can be truly representative of human variation. Eventually, we will want to expand it to include many more genomes, but this pilot project will focus on building a map structure based on the Reich-Patterson data set," Paten said.

The new Human Genome Variation Map will replace the current snarl of isolated, incompatible databases of human genetic variation with a single, fundamental representation formalized as a very large mathematical graph. The clean mathematical formulation is a major strength of this new approach, Paten said.
