SnpEff

Genetic variant annotation, and functional effect prediction toolbox. It annotates and predicts the effects of genetic variants on genes and proteins (such as amino acid changes).

Features:

  • Supports over 38,000 genomes.
  • Standard ANN annotation format
  • Cancer variants analysis
  • GATK compatible (-o gatk)
  • HGVS notation
  • Sequence Ontology standardized terms
  • Implements VCF annotation standard ANN field.

SnpSift

SnpSift annotates genomic variants using databases, filters, and manipulates genomic annotated variants.

Once you annotated your files using SnpEff, you can use SnpSift to help you filter large genomic datasets in order to find the most significant variants for your experiment.

In memory of Dr. Xiangyi Lu

Please donate

On October 22, 2017, Xiangyi Lu, a co-author on the SnpEff and SnpSift papers, died of ovarian cancer after a three year struggle.

Douglas Ruden, Xiangyi's husband and senior author on the papers, has requested that a non-mandatory gift of at least $10 for using SnpEff or SnpSift be donated to WSU to honor Xiangyi Lu. All gifts will go to a fund named "The Xiangyi Lu Graduate Student Fellowship in Bioinformatics Fund." with the goal of raising $1 million, in order to permanently endow one graduate student research position in bioinformatics every year.
