Researchers design high-fidelity Cas13 variants to minimize collateral RNA targeting

Researchers designed high-fidelity Cas13 variants using mutagenesis to reduce collateral effects, demonstrating their feasibility and efficiency in mammalian cells and animals. The most promising variant, hfCas13d, showed marked reduction in off-target genes and no detectable collateral damage, supporting its potential for gene therapy.
