The deletions are mediated by illegitimate variable(diversity)joining recombination via cryptic recombination signal sequences (RSSs). We developed a fluorescence in situ hybridization (FISH) probe set that can detect any type of IKZF1 deletion, including the commonly deleted exon 4 to 7 region. The probe set consists of a designed probe for the commonly deleted region (Cy3; red) and a bacterial artificial chromosomes clone probe for detecting the 3กไ flanking region (Spectrum Green). %U https://jmd.amjpathol.org/article/S1525-1578(17)30412-9/fulltext
