EuroGentest is an FP6 European network for the harmonization of genetic testing and for the further improvement of quality in genetic services across Europe.This proposal is to support EuroGentest2, a Coordination Action that will cover the different aspects of quality assurance of genetic practice and has all the ingredients to fulfil the needs. EuroGentest2 will be concerned with setting the targets for laboratory and health professional accreditation, by contributing to guidelines and standards, and actively interacting with the professional organizations and the policy makers. EuroGentest2 will also assist the diagnostic and clinical community and the individual laboratories and counselling units in reaching those aims by providing tools for quality management and by coordinating training activities. EuroGentest2 will extend its activities from postnatal diagnostic and predictive testing to prenatal testing, thereby building on the achievements of the FP6 SAFE network, and to direct to consumer testing.A major aim of the Coordination Action will be the creation of a European association of genetic diagnostic centres that will guarantee the future of the network.The Coordination Action will lead to the further harmonization and quality assurance of genetic practice. The patients will benefit by the improvement of the analytical and clinical quality and validity of the testing, and from improved trans-border services and information. The European diagnostics industry will benefit through a faster access of innovations to the market through the validation for diagnostic use. It will enable countries and regions with less developed health care infrastructure to develop standards for best practice of provision of clinical genetic service. The Coordination Action will also identify research needs and have the capacity to set a research agenda that corresponds to the needs of the human genetics community
