Oncotator is a web application for annotating human genomic point mutations and indels with data relevant to cancer researchers. Annotations are aggregated from the following resources:
- Gene, transcript, and functional consequence annotations using UCSC KnownGenes hg19 and mirBase reference sets.
- Common SNP annotations from dbSNP (includes data from 1000 Genomes project pilot 1, 2, and 3 studies).
- Site-specific protein annotations from UniProt.
- Druggable target data from DrugBank.
- Functional impact predictions from PolyPhen-2.
- Observed cancer mutation frequency annotations from COSMIC.
- Cancer gene and mutation annotations from the Cancer Gene Census.
- Significant amplification/deletion region annotations from Tumorscape and the TCGA Copy Number Portal.
- Overlapping Oncomap mutations from the Cancer Cell Line Encyclopedia.
- Significantly mutated gene annotations aggregated from published MutSig analyses.
- Cancer gene annotations from the Familial Cancer Database.
- Human DNA Repair Gene annotations from Wood et al.
Please see the help page for detailed information regarding all annotations.
Upload your input data below. Please note, only GRCh37/hg19 coordinates are supported and there is a maximum of 7500 alterations per input file. If you need additional help, please visit our help page or feel free to contact us directly.
