“…Motivated patients are interested in obtaining and interpreting their own genetic information, as evidenced by the rapid growth of direct-to-consumer genetic testing, online ancestry networks, pedigree-building software, and third-party variant interpretation tools that make genetic information available and accessible for patients (Kirkpatrick & Rashkin, 2017;Lee & Crawley, 2009;Leighton, Valverde, & Bernhardt, 2012;Moray, Pink, Borry, & Larmuseau, 2017;Nelson & Fullerton, 2018;Roberts et al, 2017;Stewart, Wesselius, Schreurs, Schols, & Zeegers, 2017). Similar to patientdriven research on orphan disease, wherein online patient communities have developed new methodologies, databanks, and sources of public funding for research on rare diseases (Frydman, 2009), patient-driven family studies have the potential to generate data on rare genetic variants more efficiently than researcher or laboratorydriven studies (Eggington et al, 2013).…”
