Human Whole Genome Sequencing

What is Human Whole Genome Sequencing?

Human whole genome sequencing (hWGS) enables researchers to describe the full genetic composition of individuals and characterize entire human genomes. It allows the identification of genomic variation information, including single-nucleotide polymorphisms (SNPs), insertions and deletions (InDels), structural variations (SVs), and copy number variations (CNVs) in a single and cost-efficient assay.

With extensive experience and well-developed bioinformatics know-how, Novogene delivers high-quality data, publication-ready analysis figures, and personalized results to meet different research objectives and customer needs. Novogene offers ultra-fast turnaround time, even for large projects: equipped with numerous Illumina NovaSeq 6000 platforms, Oxford Nanopore PromethION and PacBio Sequel platforms.

Novogene is capable of sequencing up to 200,000 human genomes per year at a competitive cost. Novogene hWGS service can provide data across a broad range of applications, including studies on genetic diseases, cancers, pathogenesis mechanisms, or population genetics. Multiple DNA sequencing technologies available at Novogene can identify the highly polymorphic and highly repetitive regions within the genome of interest, thereby providing a complete and accurate human genome characterization [1].

Publications of Human Whole Genome Sequencing

Human whole-genome sequencing (WGS) allows researchers to identify inherited disorders, characterize mutations that drive cancer progression, track disease outbreaks, and achieve many other research goals. Here we have summarized some outstanding academic publications that have been using novogene hWGS services.

Data Quality Control

Sequencing Error Rate Distribution

The sequencing error rate is the major confounding factor of precise detection of low-frequency variations by deep sequencing. It determines the quality of the sequencing data. The sequencing error rate is highly associated with the sequencing cycle, escalating towards the end of each read because of the consumption of chemical reagents, which is a common feature of the Illumina high throughput sequencing platform.

Note: The x-axis represents position in reads, and the y-axis represents the average error rate of bases of all reads at a position.

GC Content Distribution

GC content distribution aims to check the potential of AT/GC separation. Sample contamination, sequencing bias, and errors during library preparation can impact on the sequencing results.

Novogene hWGS GC Content Distribution

Note: The x-axis is position in reads, and the y-axis is percentage of each type of bases (A, T, G, C); different bases are distinguishable by different colors.

Alignment to Reference Genome

Sequencing Depth & Coverage Distribution

Sequencing depth and coverage illustrate the average number of pair-end clean reads which are aligned to the known reference nucleotides. The sequencing coverage distribution determines whether the identification of variations can be done with a certain degree of confidence at specific base positions.

Average sequencing depth (bar plot) and coverage (dot-line plot) in each chromosome.

Note: The x-axis represents chromosome;the left y-axis is the average depth; the right y-axis is the coverage (proportion of covered bases).

SNP/InDel/SV/CNV Calling

Single nucleotide polymorphisms (SNPs), also known as single nucleotide variants (SNVs), constitute the largest class of genetic variants in the genome. Another class of genetic variations includes small insertions and deletions (InDels) which are <50 bp in length. The InDels present in the coding region or splicing sites may cause changes in mRNA transcripts and proteins.

The number of different types of SNPs/InDels in the coding regionStructural variants (SVs) are genetic variants with relatively larger sizes (>50 bp), and they include

deletions, duplications, insertions, inversions, and translocations. SVs form the underlying genetic basis of individual differences and have potential effects on the disease and cancer susceptibility.

Advanced Analysis

Driver Gene Analysis

Heatmap of Significantly Mutated Genes

Only a few mutations related to cancer can drive tumorigenesis by affecting genes. Significantly mutated genes (SMGs) refer to those mutations that show a significantly higher mutation rate than the background mutation rate (BMR), thus indicating a positive selection during tumorigenesis. Analysis of SMGs helps us pinpoint the key genes that are critical for cancer initiation and progression.

Heatmap of significantly mutated genes (SMGs) across samples

The bar plot at the top shows the mutation rate of each sample (Mutations/Mb). The heatmap in the center shows the types of mutations of each SMG across samples. The horizontal axis represents samples, and the vertical axis represents SMGs. Different types of mutations are distinguished by different colors. The bar plot on the left side of the heatmap shows the percentage of samples affected by mutations in each SMG, and the plot on the right side shows p values of SMGs.
