Summary

Story summary

NIH researchers used gene editing to reduce severity of late-onset Tay-Sachs (LOTS) in human cell cultures and mice.
They corrected a mutation in the HEXA gene, enhancing enzyme activity.
LOTS is a rare inherited condition with no approved treatments.
The study may lead to therapies for other lysosomal storage diseases.
Future research will enhance gene delivery to the brain using adeno-associated viruses.
