mission of the Jerome Lejeune Foundation USA

While the Jerome Lejeune Foundation in France focuses on Research, Care, and Advocacy, the Jerome Lejeune Foundation USA centers its activities on Care and Advocacy. In March 2021, we opened a medical center pilot program for those with Down syndrome in Denver, Colorado, in partnership with Bella Health + Wellness.

‚ÄúThe reality of it is that by caring for the weak, by caring for the most vulnerable, we are made strong. So if we can launch this project caring for the weakest, we are made stronger. If we are made stronger, we can advocate better.‚ÄĚ

I met Jerome, many years ago, when he came to Australia. I was then a young student of medicine. I have named my medical practice after him, so inspired was I by Jerome.

Continuing the legacy of a humble giant

In 1959, Professor J√©r√īme Lejeune, doctor and researcher, discovered the cause of Down syndrome (trisomy 21).

Since then, the J√©r√īme Lejeune Foundation, has been working for individuals affected by genetic disorders (Down syndrome, Williams-Beuren syndrome, fragile X syndrome, ‚Äúcri du chat‚ÄĚ syndrome, other trisomies, monosomies and unexplained intellectual disability‚Ķ).

Serving the most¬†vulnerable and their families, the J√©r√īme Lejeune Foundation is driven by three objectives: Research, Care, Advocacy.

It implements and supports research programs designed to develop treatments for Down syndrome (trisomy 21) and other intellectual disorders of genetic origin.

The Jerome Lejeune Foundation is France’s number one funder for research in genetic disorders; the Foundation develops and funds scientific research in the United States and many other countries around the world.

We have created and funded the Jerome Lejeune Institute, a care center for specialized medical consultations.

J√©r√īme Lejeune Foundation is also highly involved in bioethical issues. In a context where ever-accelerating scientific progress and ideological pressure pose fundamental questions for society, the Foundation provides its scientific expertise and answers for difficult ethical questions.
