Sex Chromatin and Chromosome Abnormalities among 10,412 Liveborn Babies

Sex-chromatin and Sex-chromosome Abnormalities in Male Hypogonadal Mental Patients.

The present study is part of a sex-chromatin survey in a mental hospital. It has been made as a preliminary step in finding the prevalence and incidence of sex-chromosome abnormalities among patients with mental illness; and it also has the purpose of studying the psychopatho logical and genetic aspects of sex-chromosome abnormalities.

Sex chromosome abnormalities and psychiatric diseases

Excesses of sex chromosome abnormalities in patients with psychiatric diseases have recently been observed. It remains unclear whether sex chromosome abnormalities are related to sex differences in some psychiatric diseases. While studies showed evidence of susceptibility loci over many sex chromosomal regions related to various mental diseases, others demonstrated that the sex chromosome aneup...

A survey of sex chromatin abnormalities in mental hospitals.

Sex chromatin surveys have shown that an additional X chromosome is present in some or all of the cells of about 1 in 500 newborn males and of about 1 in 1000 newborn females, and that these anomalies may be 4-5 times commoner in inmates of mental deficiency institutions. The present survey was undertaken to determine the frequency of X chromosome abnormalities in patients with other mental dis...

Long-term outcome in children of sex chromosome abnormalities.

In 1967 the Medical Research Council set up a cytogenetic survey of consecutive newborn infants to establish the incidence of the variou...
