Adult Patients With Undiagnosed Conditions and Their Responses to Clinically Uncertain Results From Exome Sequencing
- Conditions
- Undiagnosed Disease
- Registration Number
- NCT03605004
- Lead Sponsor
- National Human Genome Research Institute (NHGRI)
- Brief Summary
Background:
People with conditions that are unknown or hard to diagnose may be helped by a genetic technique. It is called exome sequencing. It helps diagnose disease by unlocking all the data in a person s genetic code. But the results from it are often unclear. Uncertain results can pose problems for doctors and patients. Researchers want to learn more about how people respond when they get uncertain results.
Objective:
To study the psychological and behavioral effects of getting uncertain results from exome sequencing.
Eligibility:
Adults who have:
Had a diagnostic odyssey for at least 6 months. An example is having clinical symptoms but no diagnosis.
And had exome sequencing to try to reach a diagnosis.
Design:
Participants will choose a date and time for their interview. They will sign a form to give consent and authorization.
Participants will fill out 2 forms. One is the Intolerance of Uncertainty Short Form Scale. The other is the Perceptions of Uncertainties in Genome Sequencing Scale.
Both scales ask about what it is like to get clinically uncertain results from exome sequencing. They focus on coping and other behavioral responses.
Participants will have a phone interview. It will last for 45-60 minutes. It will be recorded and transcribed.
At the start of the call, the researcher will review the consent form with the participant. Participants will give data such as race, education, income, and how long they have been looking for a diagnosis.
Participants will read their responses to the 2 scales during the interview.
- Detailed Description
Patients pursuing exome sequencing in their quest for diagnosis will most often receive a clinically uncertain result. A clinically uncertain result is a result that has some level of objective uncertainty frequently viewed by clinicians in regard to a patient s diagnosis. A clinically uncertain result can be a result that is negative, with no reportable variants, or that includes one or more variants deemed uncertain with regard to the cause of a patient s illness. Clinically uncertain results present challenges to both providers and patients in the forms of disclosing and processing uncertain health information. This exploratory study aims to seek insight into the psychological and behavioral impact of receiving clinically uncertain results from exome sequencing. Semi-structured phone interviews will be conducted with approximately 30-40 adult patients with undiagnosed conditions who have received clinically uncertain result from exome sequencing. The interviews will focus on the experience of receiving the clinically uncertain result, with emphasis on appraisal of uncertainty, coping, and other affective and behavioral responses. Interviews will be transcribed and subjected to thematic analysis. Understanding how patients with undiagnosed conditions respond to clinically uncertain results from exome sequencing may inform providers practices around informed consent for exome sequencing and the disclosure of clinically uncertain results through a greater consideration of patient concerns and challenges with adaptation. This study may also identify implications for interventions to reduce negative effects of receiving uncertain genomic information.

- Primary Outcome Measures
Name Time Method Affective and Behavioral Responses Interview How patients describe and categorize their emotional reactions to receiving clinically uncertain result from exome sequencing. It will also explore how patients describe their behavior in response to clinically uncertain result disclosures, such as use of coping strategies and decisions to disclose their results to family and friends.
Recall and Perception Interview Extent of the patients recall of their clinically uncertain result, including their understanding of the limitations of a clinically uncertain result due to its uncertain nature. It will also explore how patients appraise the uncertainty related to their clinically uncertain result, as well as their perceptions of the relationship between their clinically uncertain result and the cause of their illness.
