Abstract
Cytogenetic examination of a 14, year, old severely retarded girl revealed a karyotype of 47 chromosomes with an extra bisatellited chromosome, a translocation between No. 22 and a chromosome in the D group. The girl had presented an early autistic syndrome beginning about 6 months of age during plastering for a congen ital luxation of the hips and receding from the age of 5. In addition, she was hyperkinetic with various aggressive and autoaggressive traits and had atypical minor epileptic fits. Data from child psychiatric examinations at 5 and 14 years are presented. The importance of giving parents information as early as possible about biological causes of mental retardation and mental illness is stressed.
