BE-FF: Base Editors Functional Finder

BE-FF identifies base editors to correct single nucleotide variations.


Taking under consideration the properties of various base editors (activity window, PAM etc.) BE-FF is able to detect precise corrections without bystander editing or synonymous corrections.

The ability of the tool to analyze the translation of a given sequence allows it to detect synonymous bystander editing.

Apparently, even some transversion mutations (i.e. purine -> pyrimidine and vice versa) can be corrected via base editing! Transversion corrections are made possible through base editing of bystander nucleotides and the reversal of the protein sequence.

The BE-FF DB presents human pathogenic SNPs that can be converted by base editing. You may also use the BE-FF online web tool to analyze your mutation of interest.
