REVIEW Chromosomal and genetic abnormalities in myeloma
Chromosomal translocations are a hallmark of lymphoid tumours. Multiple myeloma (MM) is a tumour of the plasma cell, the terminally differentiated B lymphoid cell. In recent years, a large number of chromosomal and genetic abnormalities have been detected in myeloma, the most prominent being chromosome 13q deletions and translocations affecting the immunoglobulin heavy chain (IgH) locus on chro...
متن کاملNonrandom chromosomal abnormalities in hematologic disorders of man.
A nonrandom pattern of chromosomal abnormalities occurs in bone marrow cells obtained from patients with hematologic disorders who have an abnormal karyotype involving a C group chromosome. An additional number 8 chromosome is the most common abnormality, found in more than one-half of the patients studies. An additional number 9 chromosome and the loss of all or part of a number 7 are abnormal...
متن کاملCharacterization of nonrandom chromosomal gains and losses in multiple myeloma by comparative genomic hybridization.
Clonal chromosomal changes in multiple myeloma (MM) and related disorders are not well defined, mainly due to the low in vivo and in vitro mitotic index of plasma cells. This difficulty can be overcome by using comparative genomic hybridization (CGH), a DNA-based technique that gives information about chromosomal copy number changes in tumors. We have performed CGH on 25 cases of MM, 4 cases of...
متن کاملCytogenetic analysis of chromosomal abnormalities in Sri Lankan children.
BACKGROUND Cytogenetic analysis is a valuable investigation in the diagnostic work up of children with suspected chromosomal disorders. The objective of this study was to describe the prevalence of various types of chromosomal abnormalities in Sri Lankan children undergoing cytogenetic analysis. METHODS Cytogenetic reports of 1554 consecutive children with suspected chromosomal disorders who ...
متن کاملNonrandom chromosomal changes in transitional cell carcinoma of the bladder.
Nine cases of transitional cell carcinoma (eight from the urinary bladder and one from the ureter; six noninvasive and three invasive) were subjected to detailed cytogenetic analysis with a G-banding method. The synchronization of primary cultures with methotrexate for high-resolution banding was performed in five cases. In the remaining four cases, the chromosomes were obtained from short-term...
