This clinical trial collects information on how sequencing a patient's deoxyribonucleic acid (DNA) (i.e., the genetic material) could impact their health care. This study also develops and improves ways to include genomic information from DNA sequencing into the electronic health record to create a more complete "Health Tapestry" for each participant. Sequencing of a patient's DNA leads to the detection of genetic variants some of which determine risk for disease development. Discovery of those genetic variants in a patient could result in prevention, earlier diagnosis or better therapy of disease.



I. To detect and compare the actionable genetic findings derived from whole exome sequencing (WES) testing and examine their frequency and association with family history using a large cohort of patients seen across specialties within the Mayo Clinic enterprise.

II. To assess the effect of actionable genetic findings of patients on health-care utilization, and patients acceptance.

III. To create a unique vertically integrated data asset (Mayo Clinic Health Tapestry) that links genomics and other omics information to traditional health parameters in the Electronic Medical Record (EMR) with the aim to elucidate disease formation and outcomes.

IV. Assess the frequency of hereditary cancer predisposition genes (BRCA1, BRCA2, Lynch syndrome mismatch repair [MMR] genes) through population screening using WES and the uptake of genetic counseling.

V. To study the genetic predisposition to coronavirus disease 2019 (COVID-19) disease we propose using a COVID-19 survey.


Participants receive a saliva kit, register with Helix then undergo collection of saliva sample which is returned o Helix. Participants also receive an online link to complete the About Me family history. Once sequencing is completed by Helix, ancestry/trait information and genetic findings are shared with participants and their primary provider, if applicable. Participants with positive results are offered genetic counseling and are encouraged to seek clinical confirmatory testing. Following clinical confirmation, results are scanned into the electronic health record. Participants may also undergo the collection of blood, urine, and stool samples for future studies.

Of note: Women, who are pregnant, or planning to become pregnant, can take part in this study. However, this study does not replace prenatal genetic testing. If participants have these concerns, they will be encouraged to contact their obstetrics (OB) provider or a genetic counselor to discuss further
