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.

Eligibility |
- INCLUSION CRITERIA: - Had endured a diagnostic odyssey of at least 6 months before receiving exome sequencing. A diagnostic odyssey may be defined as: - Having a set of clinical symptoms but no diagnosis OR - Having a clinical diagnosis of a broad category of disease (i.e. ataxia, muscular dystrophy) but no specific diagnosis OR - Having a clinical diagnosis composed of psychosomatic and/or descriptive diagnoses that individually define single symptoms or groups of symptoms (i.e. migraines, IBS, joint pain), but that do not explain the entire phenotype - and Had exome sequencing in an attempt to attain diagnosis - and Received post-test counseling for exome sequencing by a genetic counselor - and Received a clinically uncertain result from exome sequencing. For the purposes of this study, a clinically uncertain result is defined as one of the following options: - One or more VUSs - A negative test result (no reported variants) - and Result disclosure for exome sequencing occurred anywhere from 1 week to 7 years prior to being interviewed EXCLUSION CRITERIA: - Exome sequencing results provided a genetic diagnosis for the patient that does not fall into one of the above inclusion categories - Patient was under age 18 at time of clinically uncertain result disclosure - Patient has a cognitive disability that prevents him/her from comprehensibly answering interview questions - Patient cannot speak or understand English Patients who have since received a genetic diagnosis (from some other mechanism besides their exome sequencing test) may still participate in the study if they are able to recount their experiences around receiving this sort of exome sequencing result during the time they were undiagnosed. |

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Recall and Perception | 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. | Interview | |
Primary | Affective and Behavioral Responses | 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. | Interview |
