In Part I and Part II of the “You and the $1000 Genome” series we examined the history of the Archon X PRIZE for Genomics and the success of the International HapMap Project. Today we’ll talk about some of the ethical issues associated with efficient and inexpensive genome sequencing. The value of whole genome sequencing will only be realized if individuals believe they have complete and legal control over their genetic information. I am greatly indebted to a thorough analysis of this issue by John A. Robertson at the University of Texas School of Law (“The $1000 Genome: Ethical and Legal Issues in Whole Genome Sequencing of Individuals (pdf).” 2003 The American Journal of Bioethics 3(3):InFocus). Note that this analysis is not intended to constitute answers to any of the ethical questions – it is only meant to be part of the discourse.
In Part I of the “You and the $1000 Genome” series we examined the Archon X PRIZE for Genomics, a $10 million purse for the group that can sequence 100 genomes in 10 days for no more than $10,000/genome with an error rate below 0.001%. With today’s technology this goal is still a few years away.
But do we need an entire genomic sequence to obtain all the relevant medical information that our DNA contains? After all, 99.9% of my DNA is exactly the same as everyone else’s! Why sequence that 99.9% over and over and over if the results are the same every time? Wouldn’t it be cheaper to just sequence and then decode the 0.1%?
Sequencing that 0.1% is the goal of the International HapMap Project. HapMap stands for “Haplotype Map”, and those of you who are genetic genealogists will instantly recognize the importance of the word haplotype. The goal of the HapMap Project, begun in 2002, is to identify SNP groups (haplotypes) from a total of 270 individuals representing the Yoruba people of Nigeria, the Han Chinese in Beijing, the Japanese, and U.S. residents with northern and western European ancestry. The HapMap is essentially a catalog of all the common genetic variants in human beings.
Speaking of the $1000 genome, if you haven’t visited the 23andMe main page recently, you’ll probably want to check it out. The site has been redesigned and includes links to an About page and a Press Release page, a Contact page, and the Jobs page. I love the fact that the job benefits include “free genotyping for you and a family member or friend”!!
The front page also has a new description of the company:
“23andMe is a privately held company developing new ways to help you make sense of your own genetic information.
“Even though your body contains trillions of copies of your genome, you’ve likely never read any of it. Our goal is to connect you to the 23 paired volumes of your own genetic blueprint (plus your mitochondrial DNA), bringing you personal insight into ancestry, genealogy, and inherited traits. By connecting you to others, we can also help put your genome into the larger context of human commonality and diversity.
Over the next week and a half I will be examining the Archon X PRIZE for Genomics, a challenge from the Archon X PRIZE Foundation to foster the development of efficient and inexpensive genomic sequencing. Not only will the X PRIZE for Genomics change the face of medicine, but it will also have an ENORMOUS impact on the field of genetic genealogy, which we’ll discuss in Part IV of the series. Stay tuned for all the information you need to know about the prize, and if you have any thoughts or questions please leave a comment!
History of the Archon X PRIZE for Genomics:
In 2003 the J. Craig Venter Science Foundation announced a $500,000 Genomic Technology Prize that would be awarded to an the group whose technology significantly enhanced “the field of high throughput DNA sequencing by enabling a human genome to be sequenced for $1,000 or less.” The Foundation believed that crossing this threshold would enable the majority of individuals to afford genomic sequencing as part of medical treatment.
In 2003, researchers from around the world released a paper that suggested that 8% of all Mongolian males have a common Y chromosome because they are the descendants of Genghis Khan (See â€œThe Genetic Legacy of the Mongols,â€ 2003, Zerjal, et. al., American Journal of Human Genetics, 72: 717-721).The researchers examined the Y chromosome variability of over 2000 people from different regions in

Some scientists have hypothesized that Australian aboriginals received a portion of their DNA from an ancient hominid species called Homo erectus, which for a short time was contemporaneous with modern man. A recent study published in PNAS (Proceedings of the National Academy of the Sciences) set out to answer this question by analyzing mtDNA and Y-chromosome samples from aboriginals.
A total of 172 mtDNA and 522 Y-chromosome previously published and new sequences from aboriginal Australians and New Guineans were analyzed for mtDNA and Y-chromosome variation and were compared to the current world haplogroup tree. All of the mtDNA sequences were members of the M and N founder branches, and all of the Y-chromosome sequences fell into the C and F founder branches.
FamilySearch (a nonprofit organization sponsored by The Church of Jesus Christ of Latter-day Saints) announced today that it will provide FREE services to any and all archives and records custodians who wish to digitize, index, publish, and preserve their collections.This is, of course, on top of the ambitious project already underway to digitize and make freely available the 2 million rolls of microfilm stored in the Granite Mountain Records Vault.
This is a huge benefit for genealogists, since many more records will be freely available online.This is also a huge benefit for archivists and record depositories, since they can digitize and make available their collections for free using FamilySearchâ€™s many years of scanning experience.
I spent the morning doing a redesign of the blog.Â I should have been studying, but I’ve been meaning to give the site a new look for a while now.Â My goals were (1) to make the content the center of attention; (2) to quickly and easily provide information about the blog and subscription options to newcomers; (3) to minimize the impact of advertising (since I don’t make that much anyway!); and (4) to make the site more visually pleasing and professional.Â If you have any problems accessing information or using the site, please be sure to let me know.Â If you like the new design, let me know that too!
