Target enrichment is a powerful tool for studies involved in understanding polymorphic SNPs with phasing, tandem repeats, and structural variations. With increasing availability of reference genomes, researchers can easily design a cost-effective targeted investigation with custom probes specific to regions of interest. Using PacBio long-read technology in conjunction with probe capture, we were able to sequence multi-kilobase enriched regions to fully investigate intronic and exonic regions, distinguish haplotypes, and characterize structural variations. Furthermore, we demonstrate this approach is advantageous for studying complex genomic regions previously inaccessible through other sequencing platforms. In the present work, 12 barcoded genomic DNA (gDNA) samples were sheared to 6 kb for target enrichment analysis using the Neurology panel provided by Roche NimbleGen. Probe-captured DNA was used to make SMRTbell libraries for SMRT Sequencing on the PacBio RS II. Our results demonstrate the ability to multiplex 12 samples and achieve 1300x enrichment of targeted regions. In addition, we achieved an even representation of on-target rate of 70% across the 12 barcoded genomic DNA samples.
