Human genetic editing (engineering) is here

A “hat tip” again to Wesley Smith, who at the National Review Online blog, provided a link to this week’s report in the MIT Technology Review that the first editing of genes in human embryos in the US is underway—and apparently not yet formally published—at an academic center in Portland, Oregon.  Similar efforts have been undertaken in China, but US scientists have been a little more tentative about taking this step in humans.

In 2015, US scientists were clearly against trying to initiate a pregnancy with an IVF embryo whose genes had been altered in the laboratory.  They were, apparently, divided on whether experiments on early human embryos, sperm, or eggs in the laboratory were “responsible.”

This blog discussed the matter back then.

Earlier this year, the National Academies of Science, Engineering, and Medicine were more open to proceeding with changing human genes in a way that would be permanent—inherited from generation to generation—as long as the process was done as carefully as they thought it could be. 

The work still appears to be held very close to the vest.  Funded by private money—the law prohibits public expenditures for this kind of work on humans—the MIT report says the Oregon scientists changed some genes (the MIT reporters did not find out which ones) in “many dozens” of IVF embryos that were created and destroyed specifically for research.

The ultimate goal sounds laudable:  repairing genes that cause inherited disease.  The posts linked to above reviewed some of these arguments, or provided further links to those discussions.
