TLDR
Improvements in the gene transfer vectors used in therapeutic trials have led to substantial clinical successes in patients with serious genetic conditions, such as immunodeficiency syndromes, blindness and some cancer types.
Abstract
Improvements in the gene transfer vectors used in therapeutic trials have led to substantial clinical successes in patients with serious genetic conditions, such as immunodeficiency syndromes, blindness and some cancer types. Several barriers need to be overcome before this type of therapy becomes a widely accepted treatment for a broad group of medical diseases. However, recent progress in the field is finally realizing some of the promises made more than 20 years ago, providing optimism for additional successes in the near future.

Gene therapy of human severe combined immunodeficiency (SCID)-X1 disease

TL;DR: A gene therapy trial for SCID-X1 was initiated, based on the use of complementary DNA containing a defective gammac Moloney retrovirus-derived vector and ex vivo infection of CD34+ cells, which provided full correction of disease phenotype and clinical benefit.

Genome editing with engineered zinc finger nucleases

TL;DR: A broad range of outcomes has resulted from the application of the same core technology: targeted genome cleavage by engineered, sequence-specific zinc finger nucleases followed by gene modification during subsequent repair.
