Targeted sequencing of genomic DNA requires an enrichment method to generate detectable amounts of sequencing products. Genomic regions with extreme composition bias and repetitive sequences can pose a significant enrichment challenge. Many genetic diseases caused by repeat element expansions are representative of these challenging enrichment targets. PCR amplification, used either alone or in combination with a hybridization capture method, is a common approach for target enrichment. While PCR amplification can be used successfully with genomic regions of moderate to high complexity, it is the low-complexity regions and regions containing repetitive elements sometimes of indeterminate lengths due to repeat expansions that can lead to poor or failed PCR enrichment. We have developed an enrichment method for targeted SMRT Sequencing on the PacBio Sequel System using the CRISPR-Cas9 system that requires no PCR amplification. Briefly, a preformed SMRTbell library containing the target region of interest is cleaved with Cas9 through direct interaction with a sequence-specific guide RNA. After ligation with new poly(A) hairpin adapters, the asymmetric SMRTbell templates are enriched by magnetic bead separation. This method, paired with SMRT Sequencing’s long reads, high consensus accuracy, and uniform coverage, allows sequencing of genomic regions regardless of challenging sequence context that cannot be investigated with other technologies. The method is amenable to analyzing multiple samples and/or targets in a single reaction. In addition, this method also preserves epigenetic modifications allowing for the detection and characterization of DNA methylation which has been shown to be a key factor in the disease mechanism for some repeat expansion diseases. Here we present results of our latest No-Amp Targeted Sequencing procedure applied to the characterization of CAG triplet repeat expansions in the HTT gene responsible for Huntington’s Disease.
