SNPnexus is a web tool offering comprehensive functional annotations for genetic variations. It aids in prioritizing disease targets by analyzing effects on transcriptome/proteome and linking to genetic disease studies.
Area of Science:
- Genomics
- Bioinformatics
- Computational Biology
Background:
- Functional annotation of genetic variations is crucial for disease research.
- Prioritizing genetic targets requires comprehensive analysis of variation effects.
Purpose of the Study:
- To provide a practical guide to SNPnexus, a web-based tool for functional annotation of genetic variations.
- To detail SNPnexus's query system, annotation categories, and biological interpretation of results.
Main Methods:
- SNPnexus aggregates functional annotations for genomic variation data.
- It analyzes consequences at transcriptome/proteome levels, including deleterious effects.
- The tool infers physical/cytogenetic mapping, reports HapMap data, and identifies overlaps with regulatory elements.
Main Results:
- SNPnexus offers an integrated approach to functional annotation of genetic variations.
- It links variations to disease studies and conserved elements.
- The tool facilitates in-depth analysis of potential impacts of genetic variations.
Conclusions:
- SNPnexus is a valuable resource for researchers in disease studies and genotyping projects.
- It enhances the understanding of genetic variation impact.
- The tool aids in prioritizing genetic targets through comprehensive annotation.

Comparing Copy Number Variations and SNPs
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%...
