PRECISE DELETION OF CHROMOSOMAL SEQUENCES IN VIVO AND TREATMENT OF NUCLEOTIDE REPEAT EXPANSION DISORDERS USING ENGINEERED NUCLEASES

摘要

The present invention provides a method of treating a nucleotide repeat expansion disorder comprising delivering a pair of engineered nucleases, or genes encoding engineered nucleases, to the cells of a patient such that the two nucleases excise the nucleotide repeat responsible for the disease permanently from the genome. The invention provides a general method for treating nucleotide repeat expansion disorders and engineered nucleases suitable for practicing the method. The invention further provides vectors and techniques for delivering engineered nucleases to patient cells.
