Chromosome studies on 129 tall men surveyed in four different institutions for the care of criminal males in Pennsylvaniia showed that 1 in 11 subjects displayed aneuploidy of the sex chromosomes; specifically, five cases of 47,XYY and seven cases of Klinefelter syndrome were identified. All the aneuploid subjects were mentally ill; none had been cytogenetically diagnosed.

It is not yet known whether an XYY genotype results in a characteristic phenotype, so a genetic study of a normal population and a prospective study of newborns with various genotypes are needed which would create complex research and ethical problems.
Chromosome errors in men with antisocial behavior. Comparison of selected men with Klinefelter's syndrome and XYY chromosome pattern.
A wide spectrum of criminal offenses and psychopathology, including psychosis, was manifested in both groups, and the Klinefelter males of this series displayed a mean intelligence quotient of 80 as opposed to 84 for the 47,XYY males.
A study of the XYY syndrome in tall men and juvenile delinquents.
Four new examples of the XYY karyotype were ascertained in a survey of selected male populations, and all came from broken or unsatisfactory homes, perhaps an important factor in leading to their sociopathic behavior.
XYY Survey in an Institution for Sex Offenders and the Mentally III
Survey of 200 tall anti-social men at Atascadero State Hospital in California were studied in order to obtain additional information on the incidence of sex chromosome aneuploids.
Neurological Abnormalities in XYY Males

The XYY syndrome.
The Y chromosome disomy syndrome (47, XYY) in children with mental retardation, deviations of sex development and different genome anomalies: molecular cytogenetic studies
The study assumes a possible connection of clinical polymorphism with mosaisism, associated with the presence of abnormal cells (cell lines) in different tissues, together with the role of Y chromosome in the origin of mental retardation in children with Y- chromosome disomy syndrome and other chromosomal anomalies.
Chromosome aberrations in 2159 consecutive newborn babies.
It is suggested that D/D translocation heterozygosis will be found in random human populations with a rate of at least 1 in 1000 and probably represents the most frequent type of chromosomal rearrangement.
Impaired motor function in XYY males
Ten XYY males, most of whom are or have been in prison, showed a high frequency of hand tremor, and this and previous data suggest the tentative inference that XYY men in penal or mental-penal institutions typically have impaired motor function.
X chromosome errors in female criminals.
To the Editor:— Since W. M. Court Brown first raised the broad question of whether individuals with abnormal sex-chromosome complements "could be held in law to suffer from diminished responsibility," much attention has been accorded the legal status of criminal XXY and XYY males.


Psychopathy, Mental Deficiency, Aggressiveness and the XYY Syndrome
Preliminary findings are reported from a survey in a comparable population in the United States of mentally sub-normal male patients with “dangerous, violent or criminal propensities” found that seven of 197 inmates had an XYY sex chromosome constitution.
Aggressive Behaviour, Mental Sub-normality and the XYY Male
The purpose of this communication is to report the findings in a survey of mentally sub-normal male patients with dangerous, violent or criminal propensities in an institution where they are treated under conditions of special security.
