Cancer whole-genome sequencing (WGS) with next-generation sequencing (NGS) provides a base-by-base view of the unique mutations present in cancer tissue. It enables discovery of novel cancer-associated variants, including single nucleotide variants (SNVs), copy number changes, insertions/deletions (indels), and structural variants.
Many cancer-associated variants have been discovered using cancer genome sequencing. WGS also provides a comprehensive view of changes to a specific tumor DNA sample compared to normal DNA. As a hypothesis-free approach, cancer WGS is well-suited for comparing tumor vs. matched normal samples and discovering novel cancer driver mutations.
Cancer genomes typically contain unpredictable numbers of point mutations, fusions, and other aberrations. Since many of these alterations may be novel, and may not reside in coding regions, cancer WGS offers the most comprehensive approach for variant identification. In contrast, targeted approaches like exome sequencing may miss certain variants such as those outside coding regions.
WGS provides base-pair resolution of an entire cancer genome in a single run. The method offers a comprehensive view of the unique mutations and genomic alterations in cancer tissue, including those contributed by surrounding normal tissue and tumor clonality.
Researchers in India use whole-genome sequencing and other methods to uncover somatic and germline variants that may influence a deadly oral cancer.
WGS allows researchers to examine nucleosome patterns and infer the gene expression status of cancer driver genes in cell-free DNA.
Cancer researchers utilize WGS and other NGS methods to identify cancer-associated variants in exosomal DNA and RNA.
Researchers from Washington University in St. Louis found that using WGS to assess samples from acute myeloid leukemia and myelodysplastic syndrome patients produced more accurate results, in less time, than karyotyping or fluorescence in situ hybridization (FISH), two prevalent standard-of-care techniques.
Through tumor-normal whole-genome sequencing, researchers can compare tumor mutations to a matched normal sample. Tumor-normal comparisons are crucial for identifying the somatic variants that act as driver mutations in cancer progression.
Illumina offers push-button tools to facilitate analysis of tumor-normal WGS data.
