For each of the following genetic conditions, state which of the three types of gene therapy we covered (gene introduction, gene silencing, or gene editing) would be best suited as a treatment and briefly explain your rationale.
a) An autosomal dominant disease of the immune system that is caused by a point mutation in a single gene in white blood cells.
b) An autosomal recessive disease of the lungs caused by a lack of production of a protein (surfactant) that helps keep the surface of the lung smooth and moist.
c) An autosomal dominant neuromuscular disease caused by the production of a protein in childhood that should only be produced during fetal development.
