'Bubble' baby to return home for the holidays

A New Brunswick baby is coming home for the first time in 15 months after she was treated in American hospitals for a rare genetic immune deficiency syndrome.

Katlyn Demerchant was born with adenosine deaminase severe combined immunodeficiency [ADA SCID], sometimes referred to a "bubble boy" syndrome.

The 18-month-old toddler has spent much of her life in a hospital room at the National Institute of Health in Maryland undergoing gene therapy. (CBC)
