Int. J. Environ. Res. Public Health 2009, 6 505 23andMe is one of the largest and best-known personalized genomics services. From a buccal swab, 580,000 SNPs are scanned and mapped to 78 conditions ranging from heart attack, diabetes and a variety of cancers to lactose intolerance, baldness and earwax consistency. The raw data enumerates the rsID, chromosome number, position and genotype (Figure 11), and is owned and available for download by the consumer. The 23andMe service is ongoing, meaning that after the initial sequencing, there is continued access to the website to see additional conditions and research linked to the genetic data over time. 23andMe and other services could likely offer additional attractively-priced programs to existing members with the advent of whole genome sequencing and other new technologies. So far, several consumers have downloaded their genomic data from 23andMe and other services and posted it to the SNPedia (http://www.snpedia.com/index.php?title=SNPedia), an open source genomics resource which includes the genomes of James Watson, Craig Venter and others. Some views of the 23andMe service are shown in Figures 9 and 10. Figure 9. Excerpts from 23andMe’s condition risk profile for a sample patient. Figure 10.
