Seems like a major medical advance in the works. Stem cell experiment with cystic fibrosis made major improvements. More applicability too.

"We now have evidence that a simple intravenous injection of gene editing material can get enough of its payload to a specific tissue to ensure a large fraction of the cells there have genetic defects corrected. And that this approach can also target the stem cells in those tissues, ensuring that the effects are permanent."
