The objective of this qualitative analysis was to explore caregiver perceptions and experiences of receiving or not receiving a genetic diagnosis following genome-wide sequencing (GWS) in children with suspected genetic disorders.

One caregiver for each child completed an online survey two weeks after enrolling in the Clinical Assessment of the Utility of Sequencing and Evaluation as a Service (CAUSES) study, beginning in January 2016, and again about six months after receiving the GWS results. The survey covered the caregivers' experiences and quality of life and children's healthcare resource utilization, and provided open-ended questions for comments. The follow-up survey was completed by twenty families who had received a diagnosis with their GWS results and by twenty-two families who had not received a diagnosis. A thematic analysis of the free-text comments from both groups was performed using NVivo 11.4.2.

Caregivers from both groups expressed similar experiences of negative socioeconomic effects of caregiving, particularly related to employment and time burden. Caregivers who did not receive a diagnosis with the GWS results were generally hopeful of receiving a diagnosis in the future and reported expectations of a positive benefit from receiving a diagnosis, both in terms of access to additional resources and of positive psychological effects. The absence of a diagnosis was a source of anxiety for many caregivers. By contrast, caregivers who had received a diagnosis reported positive, neutral, and negative psychological effects from the knowledge gained; no participants commented on the consequences for access to additional services or other socioeconomic effects.

Our findings suggest that caregivers may have high expectations for what a diagnosis can provide to them and their families, which may not be fully met once a diagnosis is obtained. The study underpins the importance of patient-centered communication of genomic testing results so that families can set realistic expectations of what having a diagnosis will achieve.
