Scientists Successfully Edit Disease-Causing Mutation Out of Human Embryos

By the Editors

In a biological first, researchers report that they have used the gene editing tool CRISPR to repair the genetic mutation MYBPC3 — which causes hypertrophic cardiomyopathy — in human embryos.

However, writing in Nature, they caution that "much remains to be considered before clinical applications, including the reproducibility of the technique with other heterozygous mutations."
