In a study comprising three hospitals for mentally retarded and at the same time seriously maladjusted patients, 665 male inpatients were found on a particular day of investigation. Of these patients, all with a body length of 180 cm. or more, without exception, had a chromosome determination made. Those analysed amounted to 117, and among them were found 13 with gonosomal aneuploidy. The total frequency of gonosomal aneuploidy, like the occurrence of men with excess X-chromosomes or Y-chromosomes only, showed a statistically significant increase.
