Could this be a cure?
Genes, found deep inside our cells, 
play a role in our health.
When they are changed or missing, 
they can cause disease.
But they may also hold the key to curing it.
Gene therapy treats disease at its source. 
This is the next step in personalized medicine, 
built on decades of careful research.
It involves repairing or enhancing cells at the genetic level.
Some gene therapies are also called cell therapies 
because cells are removed and modified outside the 
body before going back into patients.
Unlike conventional medicines that often need to be 
taken over long periods of time, 
most cell and gene therapies are designed 
to be one-time treatments.
It’s a new era in medicine.
