Phenotypic and genetic characterization of adult T-cell acute lymphoblastic leukemia with del(9)(q34);SET-NUP214 rearrangement..     ///    Conventional cytogenetic analysis revealed complex chromosomal aberrations in all four SET-NUP214 rearranged cases and del(12)(p13)/ETV6 was frequently involved.     ///     SET-NUP214 rearrangement is a recently recognized recurrent chromosomal translocation mostly observed in T-ALL.     ///    Four cases (10%) of SET-NUP214 translocation were identified in our study.     ///    "In order to characterize this rare entity, we performed phenotypic and genetic characterization of SET-NUP214 rearrangement through an investigation of a series of 40 consecutive samples of adult T-ALL that was selected among 229 adult ALL cases during 4?years in a single institution. "    ///    "Our independently derived data set from a single institution confirms previous findings of SET-NUP214 rearrangement, indicates the relatively high incidence of SET-NUP214 rearrangement in adult T-ALLs, and also demonstrates comprehensive clinical, phenotypic, and genetic characteristics of this entity.
