Call for Grants

The Jérôme Lejeune Foundation is the world’s oldest and largest private funder of research into treatments for intellectual disabilities of genetic origin, especially, but not limited to, Down syndrome. The Foundation’s specific research interest is to discover a means of  treating genetic intellectual disabilities in order to improve the memory, speech, and cognition of patients.

If you are a researcher investigating genetic intellectual disability, the Scientific Advisory Board of the Jérôme Lejeune Foundation invites you to submit your research project aiming at identification of treatments to improve the cognitive deficits of patients, especially those with trisomy 21 (Down syndrome) and other rare disabilities such as fragile X, cri du chat, Rett, Williams-Beuren, Prader-Willi, Angelman, and other syndromes, excluding autism. 

Grants are offered for one or two year(s). Funding is variable in the range of EUR 20,000 per year. Clinical projects could receive more funding.

The Jérôme Lejeune Foundation also funds the organization of conferences or courses.


The application for our next funding cycle will be made available online between January 12 and March 9, 2015.
