Fluorescence in situ hybridization has become an essential detection assay in today´s routine diagnostics. However, long hybridization times of many hours to overnight are still a restrictive factor. We have refined the production process of our FISH probes to reduce background and artefacts and to improve the signal to noise ratio, particularly in short-time hybridization. Since mid-2015, one hour hybridization on lymphocytes is an integral part of quality control for all XCyting locus-specific probes at our manufacturing facility.

Several recurrent balanced translocations and inversions, and their variants, are
recognized in the WHO category AML with recurrent genetic abnormalities. Three new
cytogenetically defined entities were recently incorporated: AML with t(6;9)(p23;q34) DEK/NUP214; AML with inv(3)(q21q26.2) or t(3;3)(q21;q26.2) RPN1/EVI1 and AML (megakaryoblastic) with t(1;22)(p13;q13) RBM15/MKL1, a rare leukemia most commonly
occurring in infants.
The t(6;9)(p23;q34) DEK/NUP214 fusion occurs with an incidence of 1–5% in adult patients with AML. This translocation tends to occur in younger adults and is associated with an unfavorable prognosis at diagnosis. Although the t(6;9) is usually the sole cytogenetic aberration at diagnosis, additional karyotypic abnormalities are frequently identified during disease progression.
