Abstract In this chapter we consider gonadal maldevelopment caused by X-chromosome aberrations. As in Chapter 5, “gonadal maldevelopment” is defined broadly so that it includes defective spermatogenesis due to an extra X chromosome in XXY males and gonadal dysgenesis due to accelerated oocyte attrition in XO females. These two conditions,

Autosomal Chromosome Aberrations
1976Prior to the introduction of cytogenetic techniques in human medicine some 15 years ago, only a single chromosome aberration syndrome, Down’s syndrome, was known clinically, but its etiology was still unclear. By direct chromosome examination, it was later shown that the clinical picture of Down’s syndrome is caused by the presence of an additional No.

Food Additives & Contaminants, 1984
Three points related to the subject of chromosome-aberration tests and carcinogenicity screening are dealt with in this paper. First, the relation between chromosome rearrangements and oncogenesis is briefly discussed, to stress the relevance of cytogenetic assays to assessment of the carcinogenic potential of drugs.

Chromosomal Aberrations and Aneuploidies of Spermatozoa
2013Chromosomal abnormalities are relevant causes of human infertility, affecting 2 -14 % of infertile males. Patients with seminal anomalies could be affected by improper meiotic recombination and increased sperm chromosome aneuploidy. Since the transmission of a haploid chromosomal asset is fundamental for embryo vitality and development, the study of ...
