The correlation between age and karyotype was studied in 1425, 0 to 14.9 years old children who were diagnosed with acute lymphoblastic leukemia (ALL) or acute myeloblastic leukemia. Almost 80% of the non-Down B-cell precursor ALL cases in the 2 to 7 years frequency peak group who had aberrant cytogenetic results had either a high-hyperdiploid clone (51 to 61 chromosomes) or a translocation t(1...
MOTIVATION In current databases, there are many genes with inconsistent mapping positions between their cytogenetic annotations and sequence map positions. However, not all inconsistencies are the same. Some of them may be problematic which should be corrected in the future; while others may result from the imprecise nature of chromosomal banding which may be tolerable. It is important to strat...
Uterine leiomyomata (myomas) are associated with a variety of characteristic cytogenetic abnormalities. The significance of these chromosomal aberrations in the pathobiology of myomas remains to be determined. The present study investigated the relationship between myoma cytogenetic abnormalities and size. A total of 114 myoma specimens were obtained from 92 patients undergoing myomectomy or hy...
BACKGROUND AND OBJECTIVE Cytogenetic analysis of acute leukemia yields important information which has been demonstrated to be correlated to patient survival. A reference laboratory was created in order to perform karyotype analysis on all cases of acute leukemia enrolled in the AIEOP (Associazione Italiana Emato-Oncologia Pediatrica) protocols. METHODS From January 1990 to December 1995, 111...
Chronic kidney disease (CKD) is much more common than people recognize, and habitually goes undetected and undiagnosed until the disease is well advanced or when their kidney functions is down to 25% of normal function. Genetic and non-genetic factors contribute to cause CKD. Non-genetic factors include hypertension, High level of DNA damage due to the production of reactive oxygen species and ...
AIM Evaluation of chromosomal radiosensitivity of healthy individuals and determination those with the increased susceptibility to radiogenic cancer. METHODS Cytogenetic examination of radiation induced injuries in lymphocytes of healthy individuals (n=103) was carried out on the basis of G(2)-assay. Test system of peripheral blood lymphocytes with metaphase analysis was used. RESULTS On th...
The International Myeloma Working Group consensus updates the definition for high-risk (HR) multiple myeloma based on cytogenetics Several cytogenetic abnormalities such as t(4;14), del(17/17p), t(14;16), t(14;20), nonhyperdiploidy, and gain(1q) were identified that confer poor prognosis. The prognosis of patients showing these abnormalities may vary with the choice of therapy. Treatment strate...
