Contributing to an autism biobank: Diverse perspectives from autistic participants, family members and researchers

There has been intense debate within the autistic and autism communities about the use of autism biobanks - repositories containing biological and phenotypic materials - and of genomic autism research more broadly. Here, we sought to understand the views and experiences of those contributing to one specific biobank, the Australian Autism Biobank. We adopted a multiinformant approach, conducting semi-structured interviews with 77 people, including 18 autistic probands, 46 parents and seven siblings, all of whom donated material to the Biobank, as well as six researchers employed on the project. Specifically, we asked: what motivated participants and researchers to contribute to the Australian Autism Biobank? And how did they feel about their involvement in that process? We analysed the data using reflexive thematic analysis, adopting an inductive approach within an essentialist framework. We identified three themes, which revealed a wide diversity of viewpoints, including positive conceptualisations of autism linked to neurodiversity and more negative conceptualisations linked to hopes for the development of genetic screening and reproductive choice. These findings have implications for the meaning, value and future directions of autism science. This research has been conducted using the Australian Autism Biobank resource. A lot of autism research has focused on finding genes that might cause autism. To conduct these genetic studies, researchers have created 'biobanks' - collections of biological samples (such as blood, saliva, urine, stool and hair) and other health information (such as cognitive assessments and medical histories). Our study focused on the Australian Autism Biobank, which collected biological and health information from almost 1000 Australian autistic children and their families. We wanted to know what people thought about giving their information to the Biobank and why they chose to do so. We spoke to 71 people who gave to the Biobank, including 18 autistic adolescents and young adults, 46 of their parents and seven of their siblings. We also spoke to six researchers who worked on the Biobank project. We found that people were interested in giving their information to the Biobank so they could understand why some people were autistic. Some people felt knowing why could help them make choices about having children in the future. People also wanted to be involved in the Biobank because they believed it could be a resource that could help others in the future. They also trusted that scientists would keep their information safe and were keen to know how that information might be used in the future. Our findings show that people have lots of different views about autism biobanks. We suggest researchers should listen to these different views as they develop their work.
