What if someone handed you a tool and said that you could better the lives of people before their birth by changing their genes? Would you do it?
CRISPR-Cas9 is one such tool. It’s an efficient and effective gene-editing technology that works by tagging a section of DNA with an RNA segment, and then using a protein called Cas9 to cut the DNA at the specified point. Then, the cell’s own DNA machinery works to add or delete DNA.
This technology opens up the pathway to a variety of gene-editing applications, from eliminating HIV in living organisms to creating a potential cure for Huntington’s disease. There is especially high potential for single-gene disorders to be eradicated. For example, promising results from the successful removal of a gene known to cause fatal heart disease from the embryo will not only save lives but also prevent the passing down of the gene.
