Consent and collection of saliva samples and family history information will be obtained by an external collaborator that has received IRB approval from their local IRB. Saliva/DNA and family history information will be shared with the sponsor. The sponsor will run the saliva/DNA samples through a partner lab for genotyping. The sponsor will research the genetic information obtained for use in understanding human origins, migrations, and population structure. Select samples will also undergo whole genome or exome sequencing for purposes of research and discovery, to improve our understanding of genetic variation among world populations and to help determine which SNPs to include in future arrays for specific populations. All genetic data generated from genotyping in this research study will be securely transferred over an encrypted transfer protocol to a secure sponsor's cloud server.
