Subjects treated with gene therapy drug products in a bluebird bio-sponsored or associated clinical study will be invited to participate in this long-term follow-up study to monitor the safety and efficacy of the drug products. To date, subjects in this study have been treated with bluebird bio gene therapy drug products developed to treat the following indications: beta-thalassaemia major MedDRA version: 17.0 Level: LLT Classification code 10055579 Term: Sickle-cell beta thalassemia System O
