Summary
ONCOLINER ensures consistent somatic variant identification across cancer research by harmonizing multiple analysis pipelines. This protocol details benchmarking and reporting for improved tumor genome analysis quality.
Area of Science:
- Genomic medicine
- Bioinformatics
- Cancer research
Background:
- Interoperability of variant identification pipelines is crucial for consistent oncology research and clinical care.
- Discrepancies in somatic variant detection across different pipelines hinder reliable data interpretation.
- Standardized methods are needed to assess and improve variant calling accuracy in tumor genomics.
Purpose of the Study:
- To present a protocol for using the ONCOLINER platform to assess, improve, and harmonize somatic variant discovery.
- To enable consistent and reliable variant identification across diverse oncology research settings.
- To provide a framework for evaluating and enhancing the performance of multiple variant calling pipelines.
Main Methods:
- Acquisition of standardized benchmarking datasets for variant calling evaluation.
- Execution of user-defined variant calling pipelines using the ONCOLINER framework.
- Detailed procedures for data analysis and generation of quality assessment reports.
- Harmonization of somatic variant data from multiple pipelines for improved consistency.
Main Results:
- Development of a protocol for comprehensive assessment of variant identification pipelines.
- Generation of user-friendly reports detailing pipeline quality, scope, and potential improvements.
- Demonstration of ONCOLINER's capability to harmonize somatic variant calls across different analysis workflows.
- Facilitation of improved accuracy and consistency in tumor genome analysis.
Conclusions:
- The ONCOLINER protocol provides a robust method for evaluating and harmonizing somatic variant detection pipelines.
- Implementation of this protocol can lead to more consistent and reliable genomic data in oncology research.
- Standardized assessment and improvement of variant identification are essential for advancing precision oncology.

752.7K
DNA sequencing is a fundamental technique that is routinely used in the biological sciences. This method can be applied to a range of questions at different scales - from the sequencing of a cloned DNA fragment or the study of a mutation in a gene up to whole-genome sequencing. However, despite the widespread use of sequencing today, it was not until 1977 that Fredrick Sanger and his collaborators developed the chain-termination method to decode DNA sequences. It relies on the separation of a...

02:21Cancers Originate from Somatic Mutations in a Single Cell
11.5K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

14.0K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

The first human genome sequencing project cost $2.7 billion and was declared complete in 2003, after 15 years of international cooperation and collaboration between several research teams and funding agencies. Today, with the advent of next-generation sequencing technologies, the cost and time of sequencing a human genome have dropped over 100 fold.
