Comments on the CRISPR Gene-edited babies' case.

Twin girls were born in China in November 2018 to an HIV-positive father and an HIV-negative mother, through in vitro fertilisation in combination with CRISPR-Cas9 genome editing which altered their CCR5 genes. An investigation found that regulations were broken, and documents were forged. The government needs to address various regulatory defects, improve oversight of research, and implement institutional policies on conflict of interest.
