Comparing Copy Number Variations and SNPs

Comparing Copy Number Variations and SNPs

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%...

Single Nucleotide Polymorphisms-SNPs

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,...

Background:

Next-generation sequencing (NGS) generates numerous genetic variants per sample.
Identifying disease-causing variants requires extensive filtering and pathogenicity score analysis.
Current methods are labor-intensive and can be inefficient for large datasets.

Purpose of the Study:

To develop a flexible and efficient tool for prioritizing genetic variants.
To enable researchers to create customizable pathogenicity scores for variant analysis.
To improve the identification of disease-causal variants from NGS data.

Main Methods:

Developed VPOT (Variant Prioritization Ordering Tool), a Python-based command-line tool.
VPOT allows customizable weighting of various annotation metrics and pathogenicity scores.
Implemented additional filtering functions based on gene lists and family pedigrees.

Main Results:

VPOT generates a single, fully customizable pathogenicity ranking score.
The tool facilitates cohort analysis by prioritizing variants within a group.
VPOT demonstrated superior efficacy, flexibility, scalability, and computational performance compared to similar tools.

Conclusions:

VPOT offers a powerful and adaptable solution for genetic variant prioritization.
The tool streamlines the identification of potential disease-causal variants.
VPOT is freely available, promoting wider adoption in genetic research.
