Complex balanced chromosomal translocation t(2;5;13) (p21;p15;q22) in a woman with four reproductive failures.

abstract：BACKGROUND:Chronic myeloid leukemia (CML) is genetically characterized by the occurrence of a reciprocal translocation t(9;22)(q34;q11), resulting in a BCR/ABL gene fusion on the derivative chromosome 22, i.e. the Philadelphia (Ph) chromosome. During CML progression 60-80% of the cases acquire additional genetic change...
