1. A genome editing system, comprising:
an RNA-guided nuclease;
a first guide RNA;
a second guide RNA, and
a nucleic acid template encoding a deletion of a 13 nt region of a human HBG1 or HBG2 gene,
wherein the first and second guide RNAs comprise first and second targeting domains complementary to first and second sequences on opposite sides of positions of the 13 nt target region of a human HBG1 or HBG2 gene,
wherein one or both of the first and second sequences optionally overlaps the 13 nt target region of the human HBG1 or HBG2 gene, and
wherein at least one of the first and second targeting domains differs by no more than 3 nucleotides from a targeting domain selected from the group consisting of SEQ ID NOs: 277, 338, 327, 299, 276, 333, 278, 339, 310, 340, 940, 941, and 942.
