Simple explanation
An infant with a severe metabolic disease had a base editor designed specifically for his own mutation, made, approved and given to him — the whole process in roughly six months. He improved and went home. It is one patient, and it changes what people think is possible for ultra-rare diseases.

Musunuru and colleagues reported the design, manufacture, regulatory authorisation and administration of a patient-specific adenine base editor for severe CPS1 deficiency in an infant, delivered by lipid nanoparticle in two doses at seven and eight months of age, with clinical improvement and discharge.
