This approach, known as HLS-CATCH, allows users to apply long-range genomics to their gene or genomic region of interest, characterizing and phasing not only single nucleotide variants but also large structural variants including deletions, inversions, and translocations.
The HLS-CATCH+10x Genomics workflow is cost-effective. For instance, a 200Kb target can be isolated using HLS-CATCH with as few as two custom Cas9 complexes, whereas hybridization-capture methods would require hundreds to thousands of probes. In addition, because of the complementarity between the HLS-CATCH method and the 10x Chromium library system, sequencing reagent costs to achieve 100x phased target coverage are more than 10-fold lower than that required to obtain 100x phased whole genome data.
