Once a mutation is discovered, it can be “fixed”

A mutation in the genome cannot be "corrected" after it has already occurred. After detecting a disease-causing mutation, we must then find a medicine or other intervention that will block the broken gene because we do not now have the technology to correct a DNA error. Huntington's disease is one instance of this. In the huntingtin gene, the nucleotide CAG is incorrectly repeated, which results in Huntington's disease (Collins, 1999). There is still no cure for Huntington's disease, despite the fact that we know what causes it.

Gene therapy is an experimental method being developed by scientists to treat or prevent diseases. Instead of utilizing drugs or surgery to treat an illness, this technology may allow doctors to accomplish so by introducing a gene into the patient's cells. The majority of research has been conducted on mice, but scientists intend to develop this approach over time so that it can be used to cure ailments (What is Gene Therapy, 2012).
