Gene correction of pompe disease and other autosomal recessive disorders via rna-guided nucleases

Abstract

Described herein are guide RNAs and modified guide RNAs suitable for biallelic correction of Pompe disease. Also included are methods of modifying a target gene in a patient or in a patient-derived cell, wherein the patient has an autosomal recessive disorder with compound heterozygous mutations, the methods including delivering a first modified guide RNA, a second modified guide RNA, a Cas9 polypeptide, a biotin-binding molecule, a first biotinylated donor polynucleotide, and a second biotinylated donor polynucleotide. The first modified guide RNA and the first biotinylated donor polynucleotide correct a first diseased allele, and the second modified guide RNA and the second biotinylated donor polynucleotide correct a second diseased allele.
