Three-year-old Ally Kim home after gene replacement trial

A three-year-old with a rare and potentially fatal immune condition is back at home after being one of the first participants of a gene replacement trial.

Ally Kim, from Faringdon, Oxfordshire, was diagnosed with Chronic Granulo-matous disease last year.

He had the therapy, which involves modifying his own stem cells, when attempts to find a donor failed.
