Massive gene sequencing project aims to unlock secrets of heart disease

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

* INCLUSION CRITERIA: Group A Recruitment and enrollment to Group A is complete. For the most part, the same inclusion and exclusion criteria and justifications applied to the A1, A2, and A3 cohorts, but exceptions have been noted for some criteria. Overall, those criteria included: -Criterion #1 (A1): 25% of the participants in this cohort have known coronary artery disease (CAD), which is defined as history of: myocardial infarction, silent myocardial infarction, stent placement, re-vascularization, 50% or more arterial blockage, a calcium score greater than the 95th centile based on their age, gender and race (using the MESA calculator at www.mesa-nhlbi.org/Calcium), or a strong family history of CAD along with a personal history of a potentially CAD-related biochemical phenotype, such as elevated lipoprotein (a) (Lp(a)). * Justification: Because CAD was initially the target phenotype under study, it was critical to include a minimal number of participants with documented disease. * Criterion #2 (A1 \& A2): Individuals eligible for this study are required to be non-smokers at the time of enrollment, for our purposes defined as someone who has not smoked regularly during the previous 12 months (Wilson et al., 1998). * Justification: Because our study originally aimed to identify the genetic underpinnings of CAD, we excluded individuals who were smokers because it is a significant, known risk factor for CAD. -Criterion #3 (A1 and A2): Individuals without CAD must be 45-65 years of age, and individuals with CAD must be 35-65 years of age. * Justification: We selected our age range based on the manifestations of our target phenotype. We selected the lower limit of this cutoff in order to recruit a cohort whose coronary artery calcification (CAC) measurements range from normal to diseased, and it has been shown that abnormal CAC is infrequent below this age (Janowitz, Agatston, Kaplan, \& Viamonte, 1993). The lower limit of the age range has been expanded in the case of CAD participants to allow for the enrollment of individuals with particularly severe personal or family history of cardiovascular disease. An upper age limit of 65 was chosen to allow for longitudinal study of participants. -Criterion #4 (A3): Individuals must be 18-65 years of age. * Justification: As with the A1 and A2 cohort, an upper age limit of 65 was chosen to allow for longitudinal study of participants. However, in contrast to the A1 and A2 cohorts, a lower age limit of 18 was chosen because we are no longer primarily interested in a cardiovascular disease phenotype. -Criterion #5 (All Cohorts): Subjects must reside in the metropolitan DC and Baltimore areas or travel to the CRC on a regular basis for follow-up, or be willing to travel to the NIH as needed for protocol participation at their own expense (with the exception of some participants with CAD who had extremely compelling personal or family history of disease and we agreed to cover the cost of their transportation, meals and lodging covered for clinical visits because they could not otherwise participate). * Justification: This criterion is designed to minimize subjects reluctance to participate in ongoing study activities, such as ancillary studies and return to receive genetic testing results. -Criterion #6: First-degree relatives of enrolled ClinSeq participants are not eligible unless they fall into Group B. * Justification: These individuals share on average 50% of their genes on autosomal loci, thus possibly reducing the power of a study, such as ClinSeq , with a focus on common diseases. * Criterion #7: Individuals who are directly involved with gathering and analyzing the clinical and genotyping data, including the Principal Investigator, the Associate Investigators, the ClinSeq staff involved with the subjects at the clinical level (such as the Nurse Practitioner, Genetic counselor, etc.), and the staff at NISC involved with generating and analyzing the sequence data are ineligible. * Justification: Participation of these individuals may present a conflict of interest (COI) and lead to adverse events (AEs). -Criterion #9: Individuals who are already enrolled in another study that provides genome or exome sequencing, such as the GENE-FORECAST Study (14-HG\_0048) are ineligible. * Justification: The results that we provide will no longer be needed by the participant. In addition, the results will no longer be novel to the participant, making them ineligible for all social and behavioral research aimed at understanding the impact of return of results. Because this severely limits their participation in the project, we propose to exclude these participants. -Criterion #11: Adults who cannot or may become unable to consent are excluded from this study. * Justification: Because the study is interested in learning how people make consent decisions, their attitudes, and use of personal testing results, these individuals are excluded from the project. The following participants are/were eligible for projects related to Objectives 1A-C \& 2: * Objective 1A: Participants eligible for this project must be over 18 years old and have received a medically actionable genetic result in the last six months. --Justification: Only individuals with a result can be interviewed and surveyed because we are interested in their experiences. * Objective 1B: Recruitment and data collection are complete. Eligibility criteria included: (1) consenting to the ClinSeq project between 2012-2018, (2) completion of the Baseline Survey, and (3) being over 18 years old. * Objective 1C: Recruitment and data collection are complete. Eligibility for inclusion in this project were based on: (1) having a negative secondary finding report available from exome sequence data analysis, and (2) consenting to participate in a randomized control trial of results return. * Justification: Only participants with negative secondary findings results were included in the study since the project is focused initially on return of these results only. Objective 2: Recruitment and data collection are complete. Participants eligible for this group had a variant of interest identified in a gene/genes related to diabetes or other metabolic diseases related to glucose metabolism. --Justification: We are interested in understanding whether specific genetic variants have phenotypic consequences thus, having a variant is required for inclusion of a subject s data in our dataset. Group B Recruitment and enrollment to Group B is closed. The eligibility for Group B was distinct from Group A. Group B eligibility required: -Criterion #1: Having a relative enrolled in Group A --Justification: There are were two justifications for including relatives in Group B of the study. The first is that we wished to initiate standard of care approaches for known disease entities. For example, it is clinically indicated to perform family studies of relatives of persons with familial hypercholesterolemia to identify persons at high risk for this life-threatening disorder. The second was that we may sometimes needed additional genetic data on the families to help us determine if a genetic variant is associated with a disease phenotype (both in cases where we had some evidence of the link between the variant and disease thus the variant was suspected to cause disease and in cases where we had little to no evidence of such a link thus the variant may cause disease). -Criterion #2: Being over 18 years old, unless the phenotype under study affects children --Justification: We excluded children unless the disease causes symptoms in childhood because of our concern that such genetic testing could pose a risk to these children without known benefit. EXCLUSION CRITERIA: No Exclusion as the recruitment and enrollment is closed.
