Prevalence of fra (X) in the county of funen in Denmark is lower than expected.
Population based cytogenetic fra (X) surveys have not previously been reported from Denmark.
In the present study we present an estimate of fra (X) based on 1) information from the Danish Central Cytogenetic Registry of diagnosed fra (X) males of all age groups in all Denmark in the period 19801992 and 2) a systematic cytogenetic fra (X) survey of 175 of 8-10-year-old children with special educational needs resident in a defined, demographically representative area of Denmark (the county of Funen).
The study was performed in 1988-90 before the cloning of the FMR-1 gene.
In the county of Funen there were 7,837 male children in the age group of 8-10 years.
In the cytogenetic survey of learning disabled children, no fra (X) positive was diagnosed.
