Scientists Warn About the Consequences of Human Genetic Editing

Genetic scientists and ethics experts at an international conference in Washington stated that the application of gene editing technology on human embryos for therapeutic purposes is 'irresponsible' until safety considerations are resolved. Experts at the conference said in a statement that gene editing in human embryos for research purposes is permissible as long as the modified cells are not used to achieve pregnancy. According to Reuters, this statement was issued as discussions about the use of powerful gene editing tools on human eggs, sperm, and embryos, which could change children's DNA before birth, are increasing. This group of scientists' recommendations align with various calls for a ban on the use of CRISPR-Cas9 technology, which has quickly become a standard method for gene editing in laboratories due to its ease compared to other methods. With this technology, researchers can precisely examine genes and identify errors in gene codes, using molecular scissors to cut defective genes and insert healthy ones. Proponents of this technology argue that it helps scientists prevent hereditary diseases more quickly. Opponents are concerned about unknown effects on future generations and argue that parents may be tempted to use genetic editing to enhance their children's intelligence or physical abilities. According to AFP, this group called for the establishment of a permanent international assembly to guide research in this area in the coming years. Experts warned that if genetic changes enter the human population, 'removing them will be very difficult and will not be limited to one community or country.' They also suggested that permanent genetic enhancement on a subgroup of the population could exacerbate social inequalities. Ethical concerns have increased since Chinese researchers announced in April that they had corrected a defective gene in two embryos that were unable to grow. Jacob Korn, the scientific director of the genetics program, stated that the group's statement was 'very responsible.' The Guardian reported in September that scientists in the UK have applied for permission to conduct genetic editing on human embryos as a research project aimed at human development. A few months after Chinese researchers first announced that they had changed human embryo DNA, the request from UK scientists became controversial.
