In a previous study of lung cancer, we showed that bleomycin, a radiomimetic agent, induced breaks preferentially on chromosomes 4 and 5. The molecular cytogenetic study reported here, using chromosome painting and G banding, was designed to assess whether the chromatid breaks induced by bleomycin could survive as chromosome-type aberrations after treated lymphocyte populations were allowed to ...

Much work has been done to identify susceptibility genes in schizophrenia and bipolar disorder. Several well established linkages have emerged in schizophrenia. Strongly supported regions are 6p24-22, 1q21-22, and 13q32-34, while other promising regions include 8p21-22, 6q16-25, 22q11-12, 5q21-q33, 10p15-p11, and 1q42. Genomic regions of interest in bipolar disorder include 6q16-q22, 12q23-q24,...

We report an unusual case of a 6-year-old male child who presented with fever and a cough of one month's duration. A bone marrow aspiration and cytogenetics were suggestive of acute myeloid leukaemia with t(8;21)(q22;q22). A chest x-ray and computed tomography of the thorax showed a soft tissue lesion in the right lung. The fine needle aspiration cytology (FNAC) of this lesion was suggestive of...

Although trisomy 18 (Edwards' syndrome) or the terminal deletion syndromes of 18p and 18q have been occasionally detected, pseudoisodicentric chromosome 18 is a very rare constitutional chromosomal abnormality. We describe a case of pseudoisodicentric chromosome 18q without mosaicism, which was confirmed from fetal cells in the amniotic fluid used for prenatal diagnosis of multiple congenital a...

The translocation between chromosomes 8 and 21, t(8;21) (q22;q22), is the most frequent abnormality in acute myeloid leukemia (AML) with French-American-British type M2 (FAB-MP) morphology. The breakpoints in this translocation have been characterized at the molecular level, and the genes involved areAML 1 on chromosome 21 and €TO on chromosome 8. The rearrangement of the two chromosomes result...
