Molecular and cytogenetic characterization of a novel translocation t(4;22) involving the breakpoint cluster region and platelet-derived growth factor receptor-alpha genes in a patient with atypical chronic myeloid leukemia.
Two cases of atypical chronic myeloid leukaemia (CML) carrying the t(4;22)(q12;q11) translocation involving the breakpoint cluster region (BCR) and platelet-derived growth factor alpha receptor (PDGFRA) genes have been recently characterized.
