title: 6p+ and 9q- in two chromosomally distinct clones occurring in a case of myelodysplastic syndrome evolving to acute nonlymphocytic leukemia.
abstract: Different and unrelated chromosome changes were found to occur in a patient with a myelodysplastic syndrome with rapid evolution to acute nonlymphocytic leukemia. A 6p anomaly was found during the chronic phase and a del(9q) characterized the cells in the leukemic phase. Deletions with a breakpoint in 9q31 appeared to be associated with more aggressive disease.
