Tessera Therapeutics developing a new class of gene editors that can plug in long stretches of DNA.
This is something CRISPR cannot do, calling it "gene writing" not editing.
Gene writing is able to make either perfect deletions or simple base pair changes.
Their experts are in search of mobile genetic elements (MGEs) suited to make these DNA changes.
Identified ~6,000 retrotransposons (Tessera calls RNA writers), 2,000 transposons (DNA writers).
35 scientists have been conducting experiments in human cells to test each one.
In mouse models, team has consistently been able to use them.
This is to insert copies of large green fluorescent protein gene into animals' genomes.
What's different about Tessera is that they only need to inject a bit of RNA to make changes.
Adding chunks if reparative genetic code to treat certain conditions will be easier.
Genetic medicine to be one of the most extraordinary new categories of medicine.
