Mechanism of action

The gene therapy uses a viral vector to deliver a copy of the human COL7A1 gene to the skin, which then produces the protein collagen VII. This protein is essential for the formation of anchoring fibrils, which hold the epidermis to the dermis. In patients with dystrophic epidermolysis bullosa, the COL7A1 gene is mutated, leading to a deficiency of collagen VII and the characteristic skin blistering.
