The overall agreement (sharedSNVsAllSNVs×100%)between SNVs in cfDNA and tumor tissue was 31% (95% CI: 15-49%). NIH These pieces, called exons, are thought to make up 1 percent of a person's genome. While whole exome sequencing demonstrates some advantages over microarray-based genotyping for clinical analysis of disease risk, it also has limitations. Bayesian meta-analysis; Cancer; Cell-free DNA; Liquid biopsy; Whole exome sequencing. Together, all the exons in a genome are known as the exome, and the method of sequencing them is known as whole exome sequencing. Nonetheless, it has the characteristics of big data in large deployment. which perform important functions within a cell. Though technically challenging, whole exome sequencing (WES) of cfDNA enables thorough evaluation of somatic alterations. 2018 Feb 15;24(4):939-949. doi: 10.1158/1078-0432.CCR-17-1586.

The variability across studies on methodologies and reporting was considerable. •Focuses on the part of the genome we understand best, the exons of genes •Exomes are ideal to help us understand high-penetrance allelic variation and its relationship to phenotype. The number of detected SNVs was positively correlated with circulating tumor DNA (ctDNA) fraction (p = 0.016). In that situation certain genes must be included, so hopefully you know about that ahead of time.” Limitations of the chemistry are preventing them from moving to whole exome or whole genome platforms.
