Whole-genome sequencing (WGS) is a comprehensive method for analyzing entire genomes.

Technical Information

  • Sample QC

  • Library preparation

  • High-throughput sequencing (Illumina next-gen sequencing technology)

  • Bioinformatics analysis

  • Customer data report

  • Assessment of sequencing and quality filtering of “junk” and low quality reads

  • Mapping reads to reference sequence database(s)

  • Performing on-target and coverage statistic analysis

  • Generating variant report including: single-nucleotide polymorphism (SNPs), single-nucleotide variations (SNVs), insertions and deletions (InDels), copy number variations (CNVs), and structural variations (SV)

  • Variant annotations with multiple databases including: ClinVar, dbNSFP, DisGeNET, OMIM, PheGenI, and VEP (annotations may be unavailable for non-human samples)

  • Differential mutations analysis between selected groups including: functional annotations and pathway analysis (KEGG)

  • Customer data report – includes a summary of methods and all statistic analysis

Sequencing Depth

Recommended
Sequencing Depth*

Germline/frequent variant analysis: 30x (90Gb data per sample, or ~600M 150 bp PE reads/sample)

Somatic/rare variants: 100-1000x

Tumor vs Normal: ≥60x tumor, ≥30x normal

Population studies: 20-50x

Quality

High
Data Quality

Data quality is measured by the percentage of bases with sequencing quality scores above Q20 and Q30
