What is Oncotator?

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:

Genomic Annotations

  • Gene, transcript, and functional consequence annotations using GENCODE for hg19.
  • Reference sequence around a variant.
  • GC content around a variant.
  • Human DNA Repair Gene annotations from Wood et al.

Protein Annotations

  • Site-specific protein annotations from UniProt.
  • Functional impact predictions from dbNSFP.

Cancer Variant Annotations

Non-Cancer Variant Annotations


Please see the help page for detailed information regarding all annotations.
