Web[21]. Typical hyperdiploid clones also show gain of chromo-somes 4, 10, and 17, and the absence of this finding, as seen in this case, would be highly unusual [10, 13]. Thus, the karyotypic findings in this case suggest evolution of a near-haploid clone in spite of the fact that such a clone was not detected by conventional cytogenetics.
