No, space did not permanently alter 7 percent of Scott Kelly’s DNA (LINK)

Scientists studying Scott found that much of his gene expression changed while in space, and about 93 percent of his expression levels went back to normal when he got home. However, 7 percent of his genes related to the immune system, DNA repair, bone formation, and more were still a little out of whack when he returned. These genes are referred to as the “space genes,” according to NASA. 

That’s still a cool result, but it doesn’t mean his genetic code is significantly different. “To have 7 percent of his gene expression changed after the spaceflight does not mean that 7 percent of the DNA changed, or that those changes were necessarily due to mutations,” Nichole Holm, a geneticist at UC Davis who did not work on the Twins Study, wrote to The Verge in an email.
