SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires numpy, pandas, matplotlib, requests, and includes scripts (resource) components.

What problem does it solve?

Designing base editor sgRNAs for a target gene to enable precise nucleotide changes with minimized bystander edits.

Core Features & Use Cases

  • Automated base editor sgRNA design across human, mouse, and monkey
  • PAM-aware scanning & editing window filtering to identify guides with editable bases and minimal bystander edits
  • Output & visualization: ranked guide table, top guides, bystander report, and editing heatmaps

Quick Start

Provide a gene symbol, organism, and editor to generate a ranked list of base editor sgRNAs for that gene.

FAQPage Schema
How do I design base editor sgRNAs for a specific gene?

To design base editor sgRNAs, provide a gene symbol, organism, and editor type. The tool fetches exonic sequences from Ensembl, scans for NGG PAM sites, filters guides with editable bases, and returns a ranked guide table with bystander reports.

What is the difference between CBE and ABE sgRNA design?

CBE sgRNA design targets C bases for cytosine base editing, while ABE sgRNA design targets A bases for adenine base editing. The tool filters guides whose editing window contains the appropriate base and scores them for efficiency and bystander risk.

Can I design base editing sgRNAs for mouse and monkey genomes, not just human?

Yes, you can design base editing sgRNAs for human, mouse, and monkey genomes. Specify the organism input alongside the gene symbol and editor type to fetch the correct exonic sequences from Ensembl for PAM-aware scanning.

How does the tool handle bystander edits in base editing?

The tool evaluates bystander edits by scanning the editing window of each guide for additional C or A bases near the target. It generates a bystander report and editing heatmaps to help you minimize unwanted off-target nucleotide changes.

What inputs do I need to generate a ranked list of base editor sgRNAs?

You need a gene symbol, organism, editor type, and editing window parameters. The tool uses these inputs to fetch exonic sequences, scan PAM sites on both strands, and output ranked guide tables, top guides, and plotting figures.

Does this tool support dual-base editors for simultaneous C and A edits?

Yes, the tool supports dual-base editors alongside CBE and ABE. It scans both strands for PAM sites, filters guides where the editing window contains C or A bases, and ranks them for both single and dual-base editing applications.
