The Jérôme Lejeune Institute is recognized for its expertise in Down syndrome, but it can also deal with all intellectual disabilities of known or presumed genetic origin.
In total, more than 250 different syndromes or genetic abnormalities are followed
- Down syndrome (trisomy 21)
- 5p deletion or Cri du chat syndrome
- Fragile X syndrome
- Rett syndrome
- Williams-Beuren syndrome
- Smith-Magenis syndrome
- Prader-Willi syndrome
- Angelman syndrome
- Di George syndrome
- Many other very rare syndromes
- Many other intellectual disabilities for which the cause remains unknown but is thought to be probably genetic
For these syndromes, the competence of the Institute:
- Covers patients of all ages, from newborns to the elderly. In 2014, the Institute began pioneering standardized geriatric consultations unique in France.
- Concerns intellectual disabilities, but also all the complications associated with them.
Indeed, when someone has a genetic disease with intellectual disability, the genetic defect often affects all the cells of the body. This can result in multiple disabilities, complications associated with the principal disability.
