Priority is given to research with a translational or preclinical focus on Fragile X, which has potential to lead to improved treatment. Fellowships are initially funded for one year and are renewable for a second year, assuming successful progress and timely submission of a renewal application. Any university, hospital, or other non-profit lab in the world may apply. FRAXA funds research all over the world! Fellowships allow for a flexible use of funding; salary support for any personnel with graduate-level experience is permitted. Limit of one application per lab group. Non-transferable (only good for specified postdoc, PI, and institution). PIs must demonstrate adequate overall funding to pursue the project. Successful applicants for these grants will likely be working in established labs which have funding for supplies and any required animal handling costs. If the applicant proposes to work with a particular Fragile X model (mouse, drosophila, neural stem cells, etc.) s/he should demonstrate that this model system is already established in-house.
