    摘要: The present invention relates to compositions and methods for increasing the rate of site specific insertion of a donor DNA sequence to the genome. More specifically, the method introduces a donor DNA template containing at least one transcription factor binding site to a cell in order to favor specific insertion of a donor template sequence at a target site by homology directed repair (HDR).

    摘要: Methods for inactivating in a cell a mutant allele of the elastase, neutrophil expressed gene (ELANE gene) gene having a mutation associated with severe congenital neutropenia (SCN) or cyclic neutropenia (CyN) and which cell is heterozygous at one or more polymorphic sites selected from the group consisting of: rs10424470, rs4807932, rs10414837, rs376107533, rs3761010, rs10413889, rs3761007, rs10409474, rs3761005, rs351107, rs3761001, rs740021, rs781452480, rs371057361, rs570466264, rs1041904080, rs7250194, rs17216649, rs199720952, rs6510983, rs17223066, rs7255385, rs112639467, rs141213775, rs28591229, rs10469327, rs3834645, rs1683564, rs71335276, and rs8107095, the method comprising introducing to the cell a composition comprising: a CRISPR nuclease or a sequence encoding the CRISPR nuclease; and a first RNA molecule comprising a guide sequence portion having 17-30 nucleotides, wherein a complex of the CRISPR nuclease and the first RNA molecule affects a double strand break in the mutant allele of the ELANE gene the method optionally further comprising introduction of a second RNA molecule comprising a guide sequence portion capable of complexing with a CRISPR nuclease, wherein the complex of the second RNA molecule and CRISPR nuclease affects a second double strand break in the ELANE gene.
