Five myths about gene editing

CRISPR’s breakthrough made headlines. But are we ready to engineer designer babies?

Gene editing made great strides this month when scientists reported success using a technique called CRISPR — Clustered Regularly Interspaced Short Palindromic Repeats — to correct a serious, disease-causing mutation in human embryos. Researchers fixed a mutation that leads to hypertrophic cardiomyopathy, a relatively common inherited disease of the heart muscle that affects about 1 in 500 people.
