Recent efforts have shown that structural variations (SVs) can disrupt the 3D genome organization and induce enhancer-hijacking, yet no computational tools exist to identify such events from chromatin interaction data. Here, we develop NeoLoopFinder, a computational framework to identify the chromatin interactions induced by SVs, including inter-chromosomal translocations, large deletions, and inversions. Our framework can automatically resolve complex SVs, reconstruct local Hi-C maps surrounding the breakpoints, normalize copy number variation and allele effects, and predict chromatin loops induced by SVs. We applied NeoLoopFinder in Hi-C data from 50 cancer cell lines and primary tumors and identified tens of recurrent genes associated with enhancer-hijacking. To experimentally validate NeoLoopFinder, we deleted the hijacked enhancers in prostate adenocarcinoma cells by CRISPR/Cas9, which significantly reduced the target oncogene expression. In summary, NeoLoopFinder enables to identify critical oncogenic regulatory elements that can potentially reveal therapeutic targets.
