| Popis: | G-banded analysis performed on pretreated bone marrow samples of 36 multiple myeloma patients allowed the identification of clonal chromosome abnormalities. Abnormalities consisting of trisomies, monosomies, translocations, deletions, and marker chromosomes apparently followed a nonrandom pattern. The chromosomes involved in the production of abnormal karyotypes were numbers 1,2,3,11,12,14,17, and 18. Even though no specific chromosome pattern has been identified, the involvement of chromosomes 1, 3, and 14 was found to be more frequent. Many of the chromosomes and chromosomal breakpoints involved in these abnormalities correspond to the location of identified oncogenes or tumor suppressor genes. Hence, it is presumed that these chromosome abnormalities may be playing an important role in the genesis of multiple myeloma by altering the structure or function of oncogenes or tumor suppressor genes. |
