Research on direct-to-consumer genetic testing has shown that people are more likely to make health changes from genetic test results than from general medical advice from a doctor.

All scientists agree that due to the life-saving potential of CRISPR/Cas9 gene-editing to treat inherited human diseases that we should allow for gene-editing in human embryos.
