title: [Early diagnosis of fragile X mental retardation syndrome].
abstract: Conducting an inquiry among 32 parents of 46 children with fragile-X mental retardation, we investigated the problems on early recognition of the syndrome. From the first call for medical help until establishment of the diagnosis, on average 2 years elapsed. The family history is very important, since in 82.5% of the cases mental retardation also occurred in other family members. We recommend that investigations should be performed in all children who do not repeat words and/or do not walk without help, at the age of 18 months. A high priority must then be given to specific investigations on the X-chromosomal fragile site.
