摘要: Next-generation sequencing (NGS) technologies have transformed genomic research and the potential to revolutionize clinical medicine. However, background error rates of instruments limitations in targeted read coverage precluded detection rare DNA sequence variants by NGS. Here we describe a method, termed CypherSeq, which combines double-stranded barcoding correction rolling circle amplification (RCA)-based target enrichment vastly improve NGS-based variant detection. The CypherSeq methodology involves ligation sample into circular vectors, contain barcodes for computational adapters library preparation sequencing. is capable detecting mutations genome-wide as well those within specific genes via RCA-based enrichment. We demonstrate that correcting errors incurred during reproducibly detect down frequency 2.4 × 10(-7) per base pair, report spectra spontaneous ethyl methanesulfonate-induced across Saccharomyces cerevisiae genome.
