Fatal hereditary diseases are potential targets for CRISPR/Cas9 gene therapies using homology directed repair. Using a mouse model for hereditary tyrosinemia type I – which causes liver damage and ultimately failure due to the buildup of toxic metabolites in the tyrosine catabolic pathway – d containing the same G to A point mutation found in the human form of the disease, Yin et al where able to repair the gene and reverse the associated phenotypes. While CRISPR/Cas9 gene editing has yet to be used to correct human genetic disease, results such as this provide a promising outlook for treatment of genetic diseases.
