Question 16

When the method is perfected,it will be possible to transfer "healthy" genes into cystic fibrosis patients via aerosol inhalants to "cure" this genetic disease.Is this type of gene transfer an actual cure or is it a treatment? In other words,could this person still pass along cystic fibrosis genes?

Accepted Answer

Unless it is possible to correct the genetic defect in the person's gametes,they will still be able to pass on the genes for cystic fibrosis.However,the inhalant treatment is an important milestone in the treatment of this disease,especially if it can put a halt to the lung damage so characteristic of the cystic fibrosis patient.The life expectancy for these patients is short otherwise.
