SNPnexus is a powerful web platform for annotating and prioritizing genetic variants. Its recent upgrade enhances performance, supports larger datasets, and offers advanced filtering for efficient variant analysis.
Area of Science:
- Genomics
- Bioinformatics
- Computational Biology
Background:
- SNPnexus is an established web platform for genetic variant analysis.
- Previous versions required updates for performance and data structure.
Purpose of the Study:
- To detail the significant backend re-engineering and interface redesign of SNPnexus.
- To highlight enhanced capabilities for large-scale and comparative genetic variant analysis.
Main Methods:
- Substantial backend re-engineering and dataset restructuring.
- Redesigned user interface supporting larger queries and multi-sample analysis.
- Implementation of pre-annotation filters and updated annotation databases (GRCh37/GRCh38).
Main Results:
- Major performance improvements and increased query capacity (150,000 variants).
- New features include comparative workflows, advanced filtering, and interactive visualizations.
- Expanded annotations cover pathogenicity, population frequencies, conservation, and clinical associations.
Conclusions:
- SNPnexus offers a significantly improved, efficient, and versatile platform for functional annotation and prioritization of genetic variants.
- The updated platform supports complex analyses for disease cohort studies and evolutionary research.
- SNPnexus remains freely accessible with enhanced features for all users.

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%...
