Genome editing, or genome engineering, or gene editing, is a type of genetic engineering in which DNA is inserted, deleted, modified or replaced in the genome of a living organism. Unlike early genetic engineering techniques that randomly inserts genetic material into a host genome, genome editing targets the insertions to site-specific locations.
The impact of human gene editing on resistance to HIV infection and other body functions in experimental infants remains controversial. The World Health Organization has issued three reports on the guidelines of human genome editing since 2019, [ 41 ] and the Chinese government has prepared regulations since May 2019. [ 42 ]
With the discovery of various types of immune-related disorders, there is a need for diversification in prevention and treatment. Developments in the field of gene therapy are being studied to be included in the scope of this treatment, but of course more research is needed to increase the positive results and minimize the negative effects of gene therapy applications. [27]

Gene editing is a potential approach to alter the human genome to treat genetic diseases, [40] viral diseases, [41] and cancer. [ 42 ] [ 43 ] As of 2020 [update] these approaches are being studied in clinical trials.
The gene then needs to be mapped by comparing the inheritance of the phenotype with known genetic markers. Genes that are close together are likely to be inherited together. [12] Another option is reverse genetics. This approach involves targeting a specific gene with a mutation and then observing what phenotype develops. [12]
A prime editing guide RNA (pegRNA), capable of (i) identifying the target nucleotide sequence to be edited, and (ii) encoding new genetic information that replaces the targeted sequence. The pegRNA consists of an extended single guide RNA (sgRNA) containing a primer binding site (PBS) and a reverse transcriptase (RT) template sequence.
