/Anchor-position Editing Of An Hla Allele For Treatment Of An Autoimmune Disease
Abstract

Methods are directed to modifying an HLA allele associated with an autoimmune disease. In one example, a method includes modifying an HLA allele such that the modified HLA allele encodes a non-polar amino acid instead of a target amino acid at an anchor position. A modified HLA protein encoded by the modified HLA allele can possess altered binding affinity for at least one self-peptide. In certain embodiments, the target amino acid is at anchor position 82 in a DRB1 or DQB1 allele or at position 80 in a DPB1 allele.
