Scientists in the US have used pioneering gene - editing techniques to cure a genetic condition in utero for the first time . The researchers from Carnegie Mellon University , in partnership with researchers from Yale , used a peptide nucleic acid ( PNA)-based technique to cure mice of a genetic mutation . They injected the edited PNA into the amniotic glands of pregnant mice , resulting in 6 % of the mutations in the offspring mice being corrected , and the mice being cured of the condition . The team said the technique could provide a more reliable therapy than conventional Crispr - editing techniques .
Scientists in the US have used pioneering gene-editing technology to cure a genetic condition in utero for the first time. The researchers from Carnegie Mellon University, in partnership with colleagues from Yale, used a peptide nucleic acid (PNA)-based technique to cure mice of a blood mutation. They injected the edited PNA into the amniotic fluid of pregnant mice, resulting in 6% of the mutations in the offspring mice being corrected, and the mice being cured of the condition. The team said the technique could provide a more reliable therapy than existing Crispr-based techniques.
