Mutations cause the protein encoded by that

gene to malfunction.

When a protein malfunctions, cells that rely on

that protein's function can't behave normally,

causing problems for whole the tissue or organ.

Medical conditions related to gene mutations

are called genetic disorders.

Gene therapy is not a simple solution - it's not a molecular bandage that will automatically fix a disorder.

Now all we have to do is deliver the gene into the proper cells and put it to work. This is not an easy job. Gene delivery is one of the biggest challenges in the field of gene therapy.
