X Chromosome Aberrations

1999
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

1976
Prior 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.

Chromosome Aberrations and Cancer

Science, 1991
Cancer may be defined as a progressive series of genetic events that occur in a single clone of cells because of alterations in a limited number of specific genes: the oncogenes and tumor suppressor genes. The association of consistent chromosome aberrations with particular types of cancer has led to the identification of some of these genes and the ...

Interpreting Chromosome Aberration Spectra

Journal of Computational Biology, 2007
Ionizing radiation can damage cells by breaking both strands of DNA in multiple locations, essentially cutting chromosomes into pieces. The cell has enzymatic mechanisms to repair such breaks; however, these mechanisms are imperfect and, in an exchange process, may produce a large-scale rearrangement of the genome, called a chromosome aberration ...

Chromosomal aberrations in man

The Journal of Pediatrics, 1961
Summary The following are the most significant points to emerge in summarizing the present status of the field of human cytogenetics. 1. The human chromosome number is 46; a standard system of nomenclature has been established for identification of somatic metaphase chromosomes.

Chromosomal aberrations in malnutrition

Metabolism, 1975
The effects of feeding high (18%) and low (5%) protein diets on chromosomal aberrations in bone marrow cells of rats were investigated. Malnourished rats maintained on low protein diet had significantly higher incidence of breaks and deletions as compared to wellfed rats maintained on high protein diet. Well fed rats showed an increased aberration rate
