Gene Therapy

The process of treating diseases and improving body functions by replacing the genes inside cells.

The most common method is to employ a retrovirus as a vector to replace genes inside DNA chains using RNA. Some question the ethics of this practice, while others point to possible adverse effects that gene modifications may have on offspring.

The next-generation Genome Soldiers who had undergone gene therapy began to exhibit a curious disorder in which their bodies became bilaterally symmetrical—a common trait in extinct species. Because in some cases, this lead to sudden and unexplained death, certain units virtually collapsed. Normally, animals' bodies have an asymmetrical structure, suggesting that there was a mutation in the gene that determines asymmetry. The phenomenon was thought to be a side effect of the gene therapy.
