Exome capture and sequencing, de novo assembly, and pairwise sequence comparisons. , 2007). An effective method, termed bulked segregant exome capture sequencing (BSE-Seq) for identifying causal mutations or candidate genes was established by combining the use of a newly designed wheat exome capture panel, sequencing of bulked segregant pools from segregating populations, and the robust algorithm varBScore. Previously published deep targeted exon-capture sequencing data for all samples analysed (plus select whole-exome sequencing data) are available at EGA accession numbers EGAS00001004800 (prostate. To further exclude SNP variations caused by sequence assembly errors, exome capture and RNA-seq data were used to assemble the sequences of the mutated genes in the DCR1 and DCR2 regions. g. Rep. This type of library preparation is possible with various types. The target capture sequencing which only focuses on the functional regions in the genome such as whole-exome sequencing, with the advantages of relatively low cost, available high depth and coverage, and easy dataset to manage , has become a routine technique in basic research and clinical diagnostics. Factors contributing to variation include (i) quality of genomic DNA, 5,6 (ii) DNA extraction methods, 7,8 (iii) sequence library preparation including exome capture 9 and polymerase chain.
