For early stage research projects built on preliminary data or small projects that complement larger primary projects.
Principal investigators of any nationality and that hold a long term appointment within an academic institution, at least for the duration of the research project. Applicants must demonstrate an excellent track record and submit an outstanding proposal.
Twice a year, the Fondation Jérôme Lejeune launches calls to support fundamental, translational and clinical research projects that will strengthen the understanding, deepen the knowledge and/or will explore new therapeutic approaches for Down syndrome and other genetic diseases with intellectual disability.
The Autumn call is exclusively dedicated to Trisomy 21 research while the Spring call is aiming at supporting fundamental, translational and clinical research programs related to research on intellectual deficiencies of genetic origin solely with the exclusion of Trisomy 21.
How are projects selected?
Projects will be evaluated and ranked by the Scientific Advisory Board of the Fondation Jérôme Lejeune. External experts will be asked to review the projects if needed.
The Board of Directors of the Fondation Jérôme Lejeune will take the final decision based upon the recommendations of the Scientific Advisory Board and external reviewers.
Selection is based on compliance with the eligibility criteria, scientific excellence, novelty, feasibility and potential impact on clinical or therapeutic applications.
How much money is awarded?
Both schemes provide funding for up to 2 years:
Pilot or exploratory grants
€50.000 over 2 years
The number of funded projects will depend on the annual budget allocated by the Fondation Jérôme Lejeune to the calls.
When can I apply?
Autumn Call
Open from early-July to mid-August and is exclusively dedicated to research on Trisomy 21.
