Nature, 1967
DURING the past decade several surveys have related the incidence of sex chromosome abnormalities among the general population with that among mentally deficient patients in hospital1–3. In 1963 Wegmann arid Smith4 carried out a buccal smear survey among a male population composed of juvenile delinquents and felons. They found the incidence of positive

Chromosome abnormalities in leiomyosarcomas
Cancer Genetics and Cytogenetics, 1988Short-term cultures from seven soft tissue leiomyosarcomas were investigated cytogenetically. Sufficient mitoses for chromosome analysis were obtained in six cases, four of which had only normal karyotypes. In one tumor, an intramuscular leiomyosarcoma of the lower arm, a variety of nonclonal structural and numerical aberrations were found in two ...

Chromosomal abnormalities in sperm
Molecular and Cellular Endocrinology, 2001The use of FISH (fluorescent in situ hybridization) in decondensed sperm nuclei has allowed, during the last decade, to indirectly study the chromosome constitution of human spermatozoa. Studies in control populations have been used to set up the basal level of aneuploidy for all human chromosomes and, based on conservative estimates, the percentage of

Chromosome Abnormalities in Myelofibrosis
Acta Haematologica, 2009Cytogenetic analysis was performed on megakaryocyte-enriched cell fractions obtained by separation on discontinuous Percoll gradients from blood, bone marrow, and ascitic fluid of 12 patients with myelofibrosis with myeloid metaplasia (MMM). The most common abnormalities appeared to involve chromosomes 1, 3, 7, 8, 11, 13, 21 and 22.

Chromosome abnormalities in sperm of individuals with constitutional sex chromosomal abnormalities
Cytogenetic and Genome Research, 2005The most common type of karyotype abnormality detected in infertile subjects is represented by Klinefelter’s syndrome, and the most frequent non-chromosomal alteration is represented by Y chromosome long arm microdeletions. Here we report our experience and a review of the literature on sperm sex chromosome aneuploidies in these two conditions.

Chromosome abnormalities in leukemia.
Journal of Clinical Oncology, 1979The consistent occurrence of nonrandom chromosome changes in human malignancies suggests that they are not trivial epiphonomena. Whereas we do not understand their significance at present, one possible role which they may fulfill is to provide the chromosomally aberrant cells with a proliferative advantage as the result of alteration in the number or ...

Screening for chromosomal abnormality
Seminars in Ultrasound, CT and MRI, 1998Screening for fetal abnormalities has become one of the most high profile health care issues of modern times. This issue is predicated on major advances in health care technology that permit wider detection of fetal anomalies, including the development of more advanced biochemical markers and improvements in ultrasound imaging.

Chromosomal abnormalities in Waldenström's macroglobulinemia
Cancer Genetics and Cytogenetics, 1992We report the results of cytogenetic studies of direct bone marrow (BM) preparations and of short-term BM and peripheral blood (PB) cultures from 17 patients with Waldenström's macroglobulinemia. We noted clonal chromosome changes in 10 patients.

Chromosome abnormalities in CML
Baillière's Clinical Haematology, 1987The Ph chromosome is the hallmark of CML, where it is found in more than 90% of the cases. Cytogenetically, it usually results from a t(9;22)(q34;q11). The Ph arises in a stem cell and in chronic phase is found in all haematopoietic cell lineages, although it causes only increased granulopoiesis, and sometimes increased thrombopoiesis; furthermore ...

Chromosomal abnormalities in oocytes
Molecular and Cellular Endocrinology, 2001Since the beginning of in vitro fertilization (IVF), basic research has provided insight in the field of human reproduction, especially in genetics. Indeed, the contribution of chromosomal abnormalities to oocyte disorders and impaired embryonic development is now well known.
