The project will establish the technological building-blocks needed for the evolution of today’s diverse G2P databases into a future seamless G2P biomedical knowledge environment, by the projects end. This will consist of a European-centred but globally-networked hierarchy of bioinformatics GRID-linked databases, tools and standards, all tied into the Ensembl genome browser. The project has the following specific objectives: 1) To analyse the G2P field and thus determine emerging needs and practices; 2) To develop key standards for the G2P database field; 3) To create generic database components, services and integration infrastructures for the G2P database domain; 4) To create search modalities and data presentation solutions for G2P knowledge; 5) To facilitate the process of populating G2P databases; 6) To build a major G2P internet portal; 7) To deploy GEN2PHEN solutions to the community; 8) To address system durability and long-term financing; 9) To undertake a whole-system utility and validation pilot study. GEN2PHEN Consortium members have been selected from a talented pool of European research groups and companies that are interested in the G2P database challenge. Additionally, a few non-EU participants have been included to bring extra capabilities to the initiative. The final constellation is characterised by broad and proven competence, a network of established working relationships, and high-level roles/connections within other significant projects in this domain.
