Disruption of cadherin proteins, by genetic alteration or by changes to the structure or function of the protein, has been linked to tumor progression.

Yet another way to distinguish between therapy and enhancement might rely on the goal of the genetic alteration.

Despite the high level of genetic alteration necessary to graft sapience to them, they remain unsubtle and incapable of stealth.

This crucial genetic alteration helps create the specialized limbs required for volant locomotion.

Forest genetic resources are the basis for genetic alteration.
