title: [Screening for fragile X syndrome in handicapped boys].
abstract: From a group of 201 mentally retarded boys 149 were clinically and somatometrically examined. Chromosomal analysis for detection of a fra(X)-syndrome was undertaken, when more than 3 of the chosen examination parameters were suspicious or when anamnestic clues for X-chromosomally linked mental retardation were present. 89 boys fulfilled above requirements, 14 of these had a fra(X)-syndrome (15.7%). The following symptoms were found with outstanding frequency: hyperactivity, hypotonic muscles, enlargement of testes, increased length of hands, retarded development of speech, dermatoglyphic abnormalities. If more than 3 of these findings occur, a chromosomal analysis for exclusion of a fra(X)-syndrome should be performed.
