RT Journal Article SR Electronic T1 DNA.Land: A digital biobank using a massive crowdsourcing approach JF bioRxiv FD Cold Spring Harbor Laboratory SP 135715 DO 10.1101/135715 A1 Jie Yuan A1 Assaf Gordon A1 Daniel Speyer A1 Richard Aufrichtig A1 Dina Zielinski A1 Joseph Pickrell A1 Yaniv Erlich YR 2017 UL http://biorxiv.org/content/early/2017/05/09/135715.abstract AB Precision medicine necessitates large scale collections of genomes and phenomes. Despite decreases in the costs of genomic technologies, collecting these types of information at scale is still a daunting task that poses logistical challenges and requires consortium-scale resources. Here, we describe DNA.Land, a digital biobank to collect genome and phenomes with a fraction of the resources of traditional studies at the same scale. Our approach relies on crowd-sourcing data from the rapidly growing number of individuals that have access to their own genomic datasets through Direct-to-Consumer (DTC) companies. To recruit participants, we developed a series of automatic return-of-results features in DNA.Land that increase users’ engagement while stratifying human subject research protection. So far, DNA.Land has collected over 43,000 genomes in 20 months of operation, orders of magnitude higher than previous digital attempts by academic groups. We report lessons learned in running a digital biobank, our technical framework, and our approach regarding ethical, legal, and social implications.
