Comparing Copy Number Variations and SNPs02:26

Comparing Copy Number Variations and SNPs

18.4K
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%...

Cancer-Critical Genes II: Tumor Suppressor Genes

8.8K
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.
Such genes that act...

Cancers Originate from Somatic Mutations in a Single Cell02:21

Cancers Originate from Somatic Mutations in a Single Cell

13.8K
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...

Cancer Survival Analysis01:21

Cancer Survival Analysis

539
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Area of Science:

  • Bioinformatics
  • Genomics
  • Cancer Research

Background:

  • Tumor genome sequencing generates vast amounts of variant data.
  • Interpreting the clinical significance of these variants requires extensive data retrieval.
  • Existing methods for accessing variant information across multiple databases are time-consuming.

Purpose of the Study:

  • To develop a user-friendly web tool, VarStack, for retrieving and integrating somatic variant data.
  • To streamline the process of assessing the clinical significance of cancer variants.
  • To provide a centralized platform for accessing data from key genomic and variant databases.

Main Methods:

  • VarStack aggregates data from public databases including Catalogue of Somatic Mutations in Cancer, gnomAD, cBioPortal, ClinVar, OncoKB, CiViC, and UCSC Genome Browser.
  • Users input gene symbol, peptide change, and coding sequence change for variant queries.
  • The tool offers a batch search feature for multiple variant submissions and data export to Excel.

Main Results:

  • VarStack provides integrated somatic variant information from multiple sources through an intuitive interface.
  • The tool significantly reduces the time required for manual data retrieval from individual databases.
  • Results are presented in a tabbed format, with options for data export, facilitating workflow integration.

Conclusions:

  • VarStack enhances the efficiency of cancer variant interpretation by consolidating data from diverse sources.
  • The tool's design supports seamless integration into research workflows, saving valuable researcher time.
  • VarStack is freely available, promoting wider accessibility for cancer genomics research.
