Gene editing is planned to work on humans in the near future. Right now, as not much research and testing has been done, it is not safe for humans. Currently, this is been tested on animals and isolated human cells. The plan for one editing is to help cure the genetic diseases in humans, one example is chronic pain. Although that is not the major point of interest, chronic pain is one of the many genetic diseases that can be cured. Right now, the CRISPR-Cas9 is being tested to use in humans. The major targets are HIV/AIDS, cancer, and human embryos. Cancer is a genetic disease and the gene editor may be the first working solution for the cure of cancer. For the same purpose, the CRISPR-Cas9 is being used for treating HIV.

 

On another note, 

editing human embryos is targeted to help prevent hereditary diseases. There are many uses of the CRISPR-Cas9 which has been planned, however currently, the FDA doesn't approve of the study and editing of germline cells is illegal in the United Kingdom. In addition to all this controversy, many people fear we will take advantage of system and create designer babies. Although there are many people against gene editing, it has proved to work. Recently a teen had been cured from sickle cell disease through gene therapy. Also, in 2015, a baby girl had been cured from Leukemia through gene therapy. As the intentions of the gene editors were to take away genetic diseases and to help cure cancer, the gene editor has proved to work.
