[Delicate transition: Building-up an adult life for young people with developmental chromosomal anomalies].

A qualitative study was performed in the South of France among young people (16-25 years) affected by chromosomal anomalies: Down, velo-cardio-facial, or Williams-Beuren syndromes. We conducted interviews with them and with their parents to understand the obstacles to social participation that they most frequently face when becoming adults. Once their education comes to an end, young adults with developmental anomalies face several difficulties to develop and keep diversified social ties and to find their place in society, be it with a stable job - either in the ordinary working environment or in sheltered employment - or by attending occupational workshops.
