crispr babies

The term **"CRISPR babies"** refers to human infants whose genomes were directly edited using the CRISPR-Cas9 gene‑editing technology at the embryo stage. The phrase became widely known after a 2018 case in which a researcher in China announced the birth of twin girls whose DNA had been altered to provide resistance to HIV. The event sparked global ethical debates about gene editing, human germline modification, and the potential consequences of altering inherited DNA.
