Precision DNA editing targets root cause of severe childhood epilepsy in preclinical study

Phys · · 1159 words · By Jackson Laboratory
Gene Editing Rare Disease Treatment Medical Innovation

Researchers from The Jackson Laboratory, Broad Institute, and Children's Hospital of Philadelphia have used adenine base editing to correct a DNA mutation in mice with Dravet syndrome. The preclinical study resulted in fewer seizures and increased survival rates, suggesting a potential future therapeutic platform for rare genetic diseases.
