What to know about Gene Editing

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.

What happened

Precision DNA editing targets root cause of severe childhood epilepsy in preclinical study Stephanie Baum Scientific Editor Andrew Zinin Lead Editor Gene editing can repair a DNA error in mice that causes Dravet syndrome, a rare, incurable, and potentially…

Why it matters

After the edit, the mice have far fewer seizures and live much longer.

Common ground

As published in Science Translational Medicine, the results suggest that a one-time genetic correction could someday treat the root cause of the disease rather than just managing its symptoms.
