β¦ Synopsis
Chromosomal in situ suppression (CISS) hybridization was performed with library DNA from sorted human chromosomes 8, 9, IS, 17, 2 I, and 22 on immunologically stained bone marrow cells of four patients with a hematologic neoplasm, including two patients with myelodysplastic syndrome and trisomy 8, one patient with promyelocytic leukemia bearing the translocation t( 15; I7)(q22;q I 1-1 2), and one patient with chronic myeloid leukemia and the translocation t(922)(q34;q I I). In all patients, the results of conventional karyotype analysis could be confirmed by one-o r two-color CISS hybridization using the appropriate chromosome-specific libraries. Our results show that CISS hybridization can detect both numerical and structural chromosome changes in immunologically classified cells with high specificity and reliability. The fact that chromosome spreads of very poor quality can now be included in such analyses is a decisive advantage of this approach. In addition, the suitability of this approach for interphase cytogenetics is discussed. Genes Chrom Cancer 4:/35-/40 (I 992).
