Treatment of monogenic and digenic dominant genetic hearing loss by CRISPR-Cas9 ribonucleoprotein delivery in vivo.

Nature communications · 2023

Liposome-delivered CRISPR-Cas9 selectively cuts a dominant deafness allele in the mouse cochlea, rescuing hair cells and hearing, including in mice with two independent deafness mutations at once.
