About this study

The PopSeq Project is a prospective cohort study that will develop and implement a genomic return of results (gRoR) process in the Framingham Heart Study (FHS) and Jackson Heart Study (JHS) cohorts and explore associated medical, behavioral, and economic outcomes. The study will interpret the genomic sequences of JHS/FHS participants previously sequenced by TOPMed who have consented to genomic return of results and/or genetic testing. We will develop and apply new methods for scalable screening/ classification of genomic variants and will explore genomic penetrance by phenotyping a subset of participants in the FHS and JHS.

Read the detailed description

The objectives of this project are to: 1) Return clinically actionable genomic results to participants and track outcomes. Among living FHS/JHS participants who have consented to gRoR, we will contact those in whom a detrimental actionable variant is discovered in one of the genes noted on the ACMG recommended secondary findings list (estimate 2% of participants). 2) Improve high-throughput methods for identifying valid pathogenic variation. Refine and apply methods for high throughput screening of FHS/JHS genomes in a manner that retains high sensitivity for the detection of detrimental variants in ~3500 Mendelian disease-associated genes while reducing the false discovery rate of variants that are not pathogenic/likely pathogenic. 3) Explore aggregate penetrance for Mendelian diseases. Review phenotype data from a subset of FHS and JHS participants and compare this to genotypic data.

Data to be gathered include outcome and phenotypic data on the individuals who agree to gRoR and who learn that they have detrimental variant in one of the ACMG listed genes. These data will be self-reported through surveys and available medical records will be reviewed. Additional phenotypic data may be collected and reviewed for other non-actionable mendelian disease genes to explore genomic penetrance.

Research participants who are identified with a detrimental variant in an actionable gene may receive direct health benefits from learning this information; however, returning genomic results to healthy individuals not presenting for a medical indication may pose unexpected harms related to variant directed increases in screening and management. This study is focused on exploring the benefits and any potential harms related to returning genomic information in population-based cohorts. It will also allow us to better understand the penetrance of these variants in two populations not selected for disease status and will allow us to compare outcomes in a primarily African American population vs a Caucasian population. Developing methods to streamline variant analysis will help improve laboratory efficiency and will progress the field of variant curation and analysis.

FHS & JHS participants with an actionable genomic findingExperimentalFramingham and Jackson Heart Study participants who have had their genomes sequenced as part of TOPMed will be notified if an actionable genetic result in an ACMG v2.0 gene is identified and will be offered the opportunity to have their research result clinically confirmed by the study.
Receives: Genetic: Genomic Sequencing

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Follow Through With Disclosure

    Living JHS/FHS participants sequenced as part of the TOPMed program who were notified about an actionable genetic result that warranted having the research result verified who followed through with having their result confirmed and disclosed to their health care provider.

    Measured: From genetic result notification to 8 months post-disclosure

  2. Total Costs of Program Implementation

    We will determine the costs and associated time demands of implementing gRoR using a microcosting approach in which study staff track the amount of time they spend and the resources they use for each step of the protocol. Ranges are based on 50% to 200% of point estimates given variability in wages and prices of services.

    Measured: From the initiation of bioinformatics analysis to disclosure of confirmed actionable genetic finding (approximately 6 months).

  3. Costs of Follow-Up Care

    For follow-up medical care, we use a gross costing approach where we apply Centers for Medicare and Medicaid fee schedules to participant-reported referrals and tests.

    Measured: 1 Year Post-Disclosure Survey (from 12 months to 15 months after disclosure of confirmed results)

Secondary outcomes (5)
  1. Guideline Compliance

    Number of participants with actionable genetic results who, per the judgement of a genetic specialist, had already met clinical criteria for genetic testing based on their personal and family histories of disease.

    Measured: At the time of disclosure of confirmed findings (approximately 3 months after initial results notification)

  2. New and Modified Diagnoses

    We will examine cases to determine the percentage of individuals who report a new or modified diagnosis attributed to results disclosure.

    Measured: 6 months Post-Disclosure Survey (6-9 months after disclosure of confirmed results);1 Year Post-Disclosure Survey (from 1 year to 15 months after disclosure of confirmed results)

  3. Self-Rated Health

    A single item of self rated health derived from the SF-12v2.

    Measured: Post Disclosure Survey (up to 1 month from disclosure of confirmed results); 1 Year Post-Disclosure Survey (from 12 months to 15 months after disclosure of confirmed results)

  4. Number of Participants With Recommendations to Referrals or Services During Clinical Disclosure Sessions

    We reviewed chart notes from results disclosure sessions to determine whether referrals or services were recommended in response to genetic findings.

    Measured: From disclosure to 1 month post-disclosure

  5. Health Care Utilization

    Health care utilization in response to results disclosure reported by participants in the one year follow-up survey, including referrals, tests and/or procedures, and changes to medications.

    Measured: 1 year Post-Disclosure Survey (from 12 months to 15 months after disclosure of confirmed results)

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Yes. Results are posted in the registry (first posted 3 Aug 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Follow Through With Disclosure (time frame: From genetic result notification to 8 months post-disclosure). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
