Dr. Jerome Lejeune is the father of modern genetics and he discovered the existence of a chromosome on the 21st pair: Down Syndrome.The mission of the Jerome Lejeune Foundation USA is to provide research, care, and advocacy to benefit those with genetic intelligence disease. This is carried out by conducting, promoting, and funding therapeutically oriented medical research in the field of genetic intellectual disabilities, primarily Down Syndrome.PS: I am always asked the same question "are you related to Pr. Jerome Lejeune?" I am not related. Lejeune is a common name in the French language. I am a friend of his wife: Birthe, and of the leadership of the French foundation. I don't know if I am related to lieutenant general John Archer Lejeune, known as the "greatest of all Leathernecks" and the "Marine's Marine", either.Back in 2010, the Foundation in Paris asked me to help launch the foundation in the States, so here I am involved and happily so. As an aside note, Jerome Lejeune always had an important spiritual role in our own Lejeune family. We named our first son Jean-David "Jerome" Lejeune back in the late 90s.
