Biological Risks
There is a wide variety of biological risks associated with genetic modifications. There may be irreversible genetic changes that get passed from generation to generation with germline treatment/enhancement. New diseases may be introduced, although it is impossible to predict what they may be until they appear. Pleiotropic effects of genes are well known. For example, the gene for sickle cell anemia confers resistance to malaria. If this gene is expunged more people could die. Given the inherent variability of the technology, a new gene could insert into the targeted genome in a way that could lead to deleterious interactions with other genes. It is thus difficult for scientists to accurately predict the outcomes of genetic modification because genes operate in partnership with many other genes and the environment.

Famous quotes containing the words biological and/or risks:
“In America every woman has her set of girl-friends; some are cousins, the rest are gained at school. These form a permanent committee who sit on each other’s affairs, who “come out” together, marry and divorce together, and who end as those groups of bustling, heartless well-informed club-women who govern society. Against them the Couple of Ehepaar is helpless and Man in their eyes but a biological interlude.”
—Cyril Connolly (1903–1974)
“If the children and youth of a nation are afforded opportunity to develop their capacities to the fullest, if they are given the knowledge to understand the world and the wisdom to change it, then the prospects for the future are bright. In contrast, a society which neglects its children, however well it may function in other respects, risks eventual disorganization and demise.”
—Urie Bronfenbrenner (b. 1917)
