Why is gene therapy not a common treatment?
Gene therapy is not, unfortunately, as simple as injecting genes into the bloodstream . Genes are made of thousands of bases of DNA, and these can’t get into cells on its own, so in order to put new pieces of DNA into cells in the body, you need to package that DNA in a virus.
Can gene mutations be reversed?
genetic mutations
Reverse mutation from the aberrant state of a gene back to its normal, or wild type, state can result in a number of possible molecular changes at the protein level. True reversion is the reversal of the original nucleotide change.

Coronary artery disease (CAD) has important genetic underpinnings considered equivalent to that of environmental factors. The heritability of CAD has been estimated between 40% and 60% , on the basis of family and twin studies, a method that yields high precision despite potential bias (Vinkhuyzen et al 1 ).
Can gene therapy normalize blood glucose levels?

The first clinical gene therapy was performed in 1990 in a 4 years old girl who was battling with severe combined immunodeficiency disorder . It is due to the deficiency of an enzyme adenosine deaminase (ADA) that is crucial for the immune system to eliminate deoxyadenosine, a toxic molecule for lymphocytes.
