ANNOVAR is an efficient software tool to utilize update-to-date information to functionally annotate genetic variants detected from diverse genomes (including human genome hg18, hg19, hg38, as well as mouse, worm, fly, yeast and many others). Given a list of variants with chromosome, start position, end position, reference nucleotide and observed nucleotides, ANNOVAR can perform:
- Gene-based annotation: identify whether SNPs or CNVs cause protein coding changes and the amino acids that are affected. Users can flexibly use RefSeq genes, UCSC genes, ENSEMBL genes, GENCODE genes, AceView genes, or many other gene definition systems.
- Region-based annotation: identify variants in specific genomic regions, for example, conserved regions among 44 species, predicted transcription factor binding sites, segmental duplication regions, GWAS hits, database of genomic variants, DNAse I hypersensitivity sites, ENCODE H3K4Me1/H3K4Me3/H3K27Ac/CTCF sites, ChIP-Seq peaks, RNA-Seq peaks, or many other annotations on genomic intervals.
- Filter-based annotation: identify variants that are documented in specific databases, for example, whether a variant is reported in dbSNP, what is the allele frequency in the 1000 Genome Project, NHLBI-ESP 6500 exomes or Exome Aggregation Consortium, calculate the SIFT/PolyPhen/LRT/MutationTaster/MutationAssessor/FATHMM/MetaSVM/MetaLR scores, find intergenic variants with GERP++ score < 2, or many other annotations on specific mutations.
- Other functionalities: Retrieve the nucleotide sequence in any user-specific genomic positions in batch, identify a candidate gene list for Mendelian diseases from exome data, and other utilities.

Note that users are advised to use prepare_annovar_user.pl to make your own ClinVar databases for use in ANNOVAR (see details here, so you do not need to wait for me to update.
2018Apr16: ANNOVAR new version is available now! You can use the old link to download, or you can register again to get download email. This release contins some minor fixes and improvements.
2018Mar25: pre-computed intervar scores (version 20180118) is available on both hg19 and hg38 now with intervar_20180118 keyword. Only missense variants are included, and this is meant for a quick-and-dirty analysis of most missense variants. For a more comprehensive/formal calculation of scores, download https://github.com/WGLab/InterVar instead.
2018Mar02: About 2.4 million Brazilian genomic variants with allele frequencies are available now in hg19/hg38 coordinate. The data set comprises exomic variants of 609 elderly individuals from a census-based sample from the city of São Paulo. Please use
abraom as the keyword to download and annotate, and refer to the original publication for details.
2017Oct03: Latest clinvar (20170905) is available now through ANNOVAR in hg19 and hg38 coordinates. A long-standing problem on multi-allelic variants in ClinVar is now addressed, so that multi-allelic variants are now correctly assigned to the corresponding benign/pathogenic categories. The 20170130/20170501 versions are also updated to resolve this issue.
2017Sep29: avsnp150 is available through ANNOVAR now in hg19 and hg38 coordinate, to annotate your variants with dbSNP identifiers.
2017Sep12: Per user request, we have now made hg38 version of ensGene available through ANNOVAR directly so that users do not need to build it themselves.
2017Jul16: ANNOVAR new version is available now! You can use the old link to download, or you can register again to get download email. This release contins some minor fixes and improvements: fixed a bug in calculating upstream distance that print when -separate is specified in annotate_variation.pl, improvements to coding_change.pl to report more stopgain/stoploss and fix use-of-uninitialized-value issue, slight change to convert2annovar.pl to handle mal-formed VCF file.
2017Jun01: ANNOVAR new version is available now! You can use the old link to download, or you can register again to get download email. Important features include:
gx operation is added in table_annovar so that xref information for genes (such as gene-disease relationships) can be included (see quick start-up for examples), show complete amino acid change (such as c.35delG:p.G12Vfs*2) in gene annotaion in table_annovar.pl and coding_change.pl with
-polish argument, upstream variants now show distance to transcriptional start, splice variants at UTR now shows details, etc. (Update 2017Jun08: some users complained about format change in 2017jun01 version of table_annovar, where semicolon was used instead of comma for gene-based annotation, we have now reverted this change. Additional feature for -xreffile with multiple annotation columns has been implemented. Please re-download the code)
2017Jun01: Updated refGene, knownGene, ensGene definition and FASTA file on hg18/hg19/hg38 coordinates are available to download with
