The map of the gene-editing revolution
The CRISPR Atlas
Explore the technologies, treatments, diseases, scientists, companies, clinical trials and discoveries shaping the future of genetic medicine.
Start where you actually are
This site is written for very different readers at once. Each door below leads into the same database from a different angle — nothing is dumbed down, and nothing assumes a biology degree.
New to all of thisStart with what DNA is and build up. No background needed.
A patient or familyWhat is approved, what is only in trials, and how to tell the difference.
Following the industryWho is developing what, at which stage. Information, never advice.
Here for food and farmingGene-edited crops and livestock, and why the rules differ by country.
Explore gene editing
Seven ways scientists change genetic material. Each page opens with a plain-language explanation, then goes as deep as you want.
CRISPR-Cas9A protein that can be programmed with a short RNA guide to find one specific sequence in a genome and cut it.
Base EditingChemically converts one DNA letter into another at a chosen position, without cutting both strands of the double helix.
Prime EditingWrites a new stretch of DNA sequence directly into a chosen site, using a guide that carries the replacement text with it.
CRISPR-Cas12A family of CRISPR nucleases that cut DNA leaving staggered ends, use a different sequence requirement from Cas9, and can be smaller.
CRISPR-Cas13Targets RNA rather than DNA, so it can silence a gene's message without touching the genome itself.
Cas14 and miniature Cas systemsUnusually small CRISPR nucleases — roughly a third the size of Cas9 — discovered in archaea and bacteriophages.
RNA EditingChanges letters in the RNA message rather than in the DNA, so the effect is real but temporary and the genome is untouched.
Compare them side by sidePrecision, cutting, cargo size, delivery, maturity, risks

Scientists who changed the field
What each person actually contributed — attribution in this field is contested, and we say where.
Jennifer DoudnaStructural biochemist who, with Emmanuelle Charpentier, showed that Cas9 could be programmed with a single guide RNA to cut chosen DNA — and shared the 2020 Nobel Prize in Chemistry for it.
Emmanuelle CharpentierMicrobiologist who discovered tracrRNA, the missing component of the CRISPR-Cas9 system, and shared the 2020 Nobel Prize in Chemistry with Jennifer Doudna.
Feng ZhangBioengineer who led one of the first demonstrations of CRISPR genome editing in human cells and discovered several new CRISPR systems including Cas12a and Cas13.
David LiuChemical biologist whose laboratory invented base editing and prime editing — the two techniques that changed gene editing from cutting to writing.
George ChurchGeneticist whose laboratory independently demonstrated CRISPR editing in human cells in 2013, and a founder of an unusually large number of genomics companies.
Virginijus ŠikšnysLithuanian biochemist who independently showed that Cas9 could be programmed to cut DNA, publishing in 2012 — and whose contribution is often omitted from popular accounts.

What is RNA?
RNA is DNA's working copy — a temporary, single-stranded version the cell makes when it needs to use a gene.

What is a mutation?
A mutation is a change in DNA sequence. Most do nothing, some cause disease, and a few are beneficial.
Gene editing by the numbers
Live counts from the Atlas database — these are the number of records we hold, not an estimate of the size of the field.
Counts refresh on every page load. “Approved” means a national medicines regulator has authorised at least one product; it does not mean the therapy is available or suitable for any particular person.
