As part of her doctoral research, Sudeepa Abeysinghe is asking people who have purchased genomic tests to complete the â€œUser Experiences of Direct-to-Consumer Genomic Testing Surveyâ€.Â According to Sudeepa, the survey focuses on the consumer experience and is completely independent of any testing company.
Although Iâ€™m late on reporting this (it was already covered by GenomeWeb, for example), I thought I would mention it in case anyone has missed the previous coverage and might be interested in completing the survey.
This is an opportunity for genetic genealogists to share their experiences and voice their thoughts regarding DTC genomic testing.
An article in the United Arab Emirate newspaper The National (wikipedia) does a terrific job of highlighting recent research from Family Tree DNA.Â The story – â€œDNA could illuminate Islamâ€™s lineageâ€ â€“ discusses research that has attempted to elucidate the Y-DNA signature of Mohammed.Â Although Mohammed did not have a son, he had a daughter who married her paternal second cousin, thus passing to Mohammedâ€™s grandchildren the same Y-DNA.Â From the article:
â€œFor almost 1,600 years, the title Sharif, Sayyed, or Habib has been bestowed on Muslims who have been able to trace their roots back to the Prophet Mohammed through intricate family trees, oral histories and genealogical records. But now an American DNA lab says it may have identified the DNA signature of descendants of the Prophet Mohammed, and perhaps the prospect of a direct, more accurate means of confirming or identifying such a connection.â€
Roughly 6 million years ago, the Hominini subtribe of the Hominidae family tree (the so-called â€œgreat apesâ€) diverged into two known branches, with one branch (genus Pan) resulting in modern-day Chimpanzees and Bonobos, and the other branch (genus Homo) resulting in modern-day humans.
Since there has only been 6 million years of divergent evolution, Chimpanzees/Bonobos and Humans share a great deal of DNA sequence in common (although estimates vary widely and typically depend on what, exactly, is being considered in the comparison).
The Close Cousins DNA Project
On May 31, 2008, the Close Cousins DNA Project was launched by Bill Davenport as a result of a discussion on the Genealogy-DNA mailing list regarding the relatedness of human and chimpanzee Y-DNA.Â From the launching post:
Itâ€™s very interesting to see the responses of these anonymous individuals, particularly since they are from different countries.
For example, both were asked why they decided to purchase the 23andMe test – â€œWas it to test your ancestry or genetic health risk factors?â€Â Interestingly, for both individuals ancestry was the motivating factor behind testing.Â More support for my conclusion that these companies should strongly promote the ancestral aspects of their products.
Here are a few examples of other questions in the interviews:
The Virginia Commonwealth University Life Science Center has released the results of the VCU Life Sciences Survey and I thought I’d share some of the interesting results.
The most surprising result of the survey is that 80% of surveyed adults favor making genetic testing â€œeasily available to all who want it,â€ similar to values in 2001 and 2004.Â Donâ€™t tell this to the New York and California Departments of Health!
The Benefits Outweigh the Risks
54% of adults believe that the benefits of genetic testing outweigh the risks, while 25% believe that the risks outweigh the benefits.Â Itâ€™s interesting to see the education breakdown of this question.Â 44% of people with a high school degree or less believe that benefits outweigh risks, compared to 67% of people with a college degree or more.Â And 29% of people with a high school degree or less believe that risks outweigh benefits, compared to 20% of those with a college degree or more.
The talk was a Syracuse Symposium event, and the first big event ever to be held in Syracuse University’s new $110 million Life Sciences Center.Â I thought it was fitting that the first event to celebrate the future of the new life sciences building was a lecture that examined the collective genetic journey of mankind.
Dr. Wells began by giving the audience a very brief introduction about DNA and genetic genealogy.Â He included a great quote that “The question of origin is actually a question about genealogy.”Â For those that are not familiar with the Genographic Project, it was launched in 2005 and includes three primary missions:
The Personal Genome Project (PGP) was established to analyze and publicly share the genomes and personal information of up to 100,000 volunteers in order to advance understanding of “genetic and environmental contributions to human traits and to improve our ability to diagnose, treat, and prevent illness.”Â In the first phase of the PGP, ten volunteers (the “First 10″ – see information about the First 10 here on my blog and at the PGP website) have had their DNA analyzed and have given their personal information.
Last month, George Church, the PGP’s principal investigator, reported that the project expected to publish data about the First 10 on its website in mid- to late October.Â Church might have meant genotype (i.e. sequencing) information, since some information about phenotype, health history, and medication has already been posted on the PGP website.Â There is information about each of the 10 participants, although there is currently no active link to their genetic information:
The American Society of Human Genetics is having its 58th Annual Meeting in November.Â As I was looking through the meeting abstracts, I noticed that there were a number of abstracts that dealt with topics related to genetic genealogy.Â I thought some of you would be interested in getting an advance look at genetic genealogy research that will be publicly released and published over the next year or two.Â Although I didn’t include the whole abstracts for most of them, I did include a link for further investigation.Â (Note: I got this idea from Dienekes’ Anthropology Blog).
Interestingly, the first five abstracts all include researchers from the Sorenson Molecular Genealogy Foundation, showing how much the Foundation is providing to the genetic genealogy community.
“[A]ffordable whole-genome sequencing is getting closer and closer every day (my prediction – which is based solely on my own educated guess – is that I will be able to sequence my entire genome for $1,000 or less by the end of 2009).”
It was pretty bold at the time, and I’ve since wondered if I was too optimistic, but now comes news that at least one other person agrees with my prediction.Â Harvard professor and genetics researcher George Church – also principal investigator for the Personal Genome Project (PGP) – stated at two conferences, one last week and one this week, that by mid-October of 2008, 36-fold coverage of the human genome will be available for $5,000.Â Church went on to say that the $1,000 human genome will be available by the end of 2009.
Welcome to the September 14, 2008 edition of Gene Genie!Â Bloggers have begun to pick up posting with the end of summer, and it seems like everyday there’s a bunch of new interesting posts about the human genome.
