What is inheritable genetic modification?
A: Inheritable genetic modification (IGM) means changing the genes in egg or sperm cells, or in the cells of very early embryos, in order to modify the traits possessed by the next generation of people, who may pass them on in turn to their children. It is also known as “germline engineering.”
What is inheritable change?
Changes in genes can cause a wide range of conditions. Sometimes a changed gene is inherited, which means it is passed on from parent to child. Changes in genes can also occur spontaneously.
Is germline editing heritable?
Germline gene editing raises particular ethical and safety issues. Gene editing in a young child or adult creates changes that may affect the individual, but are not passed on to his or her children. Germline editing, also known as heritable genome editing, creates changes that are inherited by subsequent generations.
How much does genetic modification cost?
Developing a gene therapy can cost an estimated $5 billion. This is more than five times the average cost of developing traditional drugs.
Is genetic modification legal?
Without the FDA’s approval, implantation of a genetically modified human embryo is illegal in the USA. However, genetically modifying human embryos for research purposes are permitted, even though such experiments remain ineligible for public funding.
Should gene editing be performed on human embryos?
Editing genes in human embryos could one day prevent some serious genetic disorders from being passed down from parents to their children — but, for now, the technique is too risky to be used in embryos destined for implantation, according to a high-profile international commission.
Why is germ cell gene therapy unethical?
The idea of germline gene therapy is controversial. While it could spare future generations in a family from having a particular genetic disorder, it might affect the development of a fetus in unexpected ways or have long-term side effects that are not yet known.
