SUMMARY
Aims: To investigate genomic alterations of Japanese biliary tract cancers
Methods: DNAs were extracted from biliary tract cancer and paired non-cancer (normal) tissues. NGS libaraies were prepared by using TruSeq DNA Sample Prep kit (Illumina) for whole genome sequencing (WGS) and Nextera Rapid Capture kit (Illumina) / Agilent SureSelect Exome V5 kit for whole exome sequencing (WES). Sequencing was perfomred by Illumina HiSeq 2000/2500 or NovaSeq 6000.
Participants/Materials: WGS and WES data of Japanese biliary tract cancer patients.

Data with bad base quality and high %GC content were removed. Aligment: Data matched for the following condition were removed. - Low mapping rate - Different insert size - Gender information mismatch between meta-data and genotype data - Suspected sex chromosome aberration Genotyping: GATK’s best practices includes a variant filtering step following Variant Quality Score Recalibration (VQSR) - DP/GP (DP < 5, GQ < 20, DP > 60, GQ < 95 ) - Heterozygosity (F>=0.05) - Hardy-Weinberg equilibrium (p < 10^-6） - Repeat & Low Complexity Principal Component Analysis (PCA): PCA was performed with individuals included in the 1000 genomes project and outliers from Japanese cluster were removed.
After these filtering steps, variants located in the regions listed as the HighConfidenceRegion (Genome-In-A-Bottle project) were flagged. |
