It is also found in a fraction of <em>BCR-ABL1</em>-negative B-cell precursor acute lymphoblastic leukemias, and early studies showed it was associated with a higher risk of relapse. Therefore, screening tools are needed for evaluation in treatment protocols and possible inclusion in risk stratification. Besides monosomy 7 and large 7p abnormalities encompassing <em>IKZF1</em>, most <em>IKZF1</em> alterations are short, intragenic deletions. Based on cohorts of patients, we mapped the microdeletion breakpoints and developed a breakpoint-specific fluorescent multiplex polymerase chain reaction that allows detection of recurrent intragenic deletions. This sensitive test could also detect <em>IKZF1</em&gt; subclonal deletions, whose prognostic significance should be evaluated. Moreover, we show that consensus breakpoint sequences can be used as clonal markers to monitor minimal residual disease. This paper could be useful for translational studies and in clinical management of BCP-ALL.}, number={4}, journal={Haematologica}, author={Aurélie Caye and Kheïra Beldjord and Kelly Mass-Malo and Séverine Drunat and Jean Soulier and Virginie Gandemer and André Baruchel and Yves Bertrand and Hélène Cavé and Emmanuelle Clappier}, year={2013}, month={Mar.}, pages={597-601} }
