Scientists have discovered long ago that some people respond to certain drugs differently from other patients  For example, a certain type of anesthetic muscle relaxant can cause certain people to be unable to breathe  Later, scientists discovered that this phenomenon is caused by a specific gene they have
This also brings up a question: can the study of genetic differences between people promote the development of more advanced treatments in medicine, that is to say, tailor-made medicine can be based on individual genes? Scientists have identified a number of genes that interact with drugs, but it may be too early to realize it
The research results of genetics have been widely used in medicine.
