Could CRISPR cure rare diseases before birth? Scientists are getting closer

Researchers are advancing fetal gene editing as a potential way to treat rare genetic disorders before they cause irreversible damage, with CRISPR-based approaches among the techniques under investigation. The strategy targets conditions in utero, when intervening early could prevent the organ and neurological harm that accumulates before birth. The work remains experimental, and questions around delivery methods, safety and long-term effects are still being studied. The approach matters because many rare genetic diseases currently have limited or no effective treatments once symptoms appear. What to watch next is early-stage trial data and whether regulators clear fetal gene-editing candidates for broader testing.
