Do you have a burning question about genetics that’s been keeping you up at night? Ever wonder why the combination of red hair and brown eyes is so rare? There are two great resources currently available online for anyone who is curious about genetics.
AsktheGeneticist is a partnership between the Department of Human Genetics at EmoryUniversity and theDepartment of Genetics at the University of Alabama at Birmingham.The mission of AsktheGeneticist â€œis to answer questions about genetic concepts, and the etiology, treatment, research, testing, and predisposition to genetic disorders.â€ AsktheGeneticist has a genetic genealogy section, but itâ€™s pretty sparse.
The Tech Museum of Innovation in San Jose, California has partnered with the Department of Genetics at StanfordUniversity to present â€œGenetics: Technology with a Twist.â€The interactive site has an â€˜Ask The Geneticistâ€™ section where you can ask a Stanford geneticist a question.
1.You got those big blue eyes from your grandmother, but chances are you inherited less desirable genes as well.We inherit our DNA from our parents, who inherited it from their parents.Since we all possess genes that can cause or contribute to disease, knowing oneâ€™s DNA and family medical history can be a great resource for someone who learns they have a genetic disorder.
2.Full genome sequencing is right around the corner!The X-prize quest for the $1000 genome will lead to efficient and affordable whole-genome sequencing.As commercial companies crop up and compete for customerâ€™s business, leading to even lower prices.
3.Your grandmotherâ€™s DNA contains clues to her ancestry.X-chromosome, mtDNA, and autosomal genealogy tests contain clues to a personâ€™s ancestry, both recent and ancient.
I just wanted to let my readers know that posting will be on the light side this week because of exams.Â Â I am finishing up my first year of law school, so Constitutional law and Property are taking up most of my time.Â And stay tuned, I have some big projects in the works for the very near future!
Scienceroll just posted a hilarious video called the “DNA-ting Game“, an advertisement for Caliper Life Sciences which is a spoof on 1970’s “The Dating Game.” If you think science humor is funny, you’ll love this video. I highly recommend you go check it out. For a little background information, they talking about analyzing DNA samples using gel electrophoresis. The video is actually an elaborate advertisement for an alternative to electorphoresis.
There are some other funny videos I’ve seen as well, including the great advertising campaign from Biocompare. There are three commercials – here, here, and here. They’re another example of biotechnology companies jumping into this field of advertising. In our lab we typically made decisions based on price, but who knows what effect appealing to our sense of humor might have?
I was very surprised when genetic testing revealed that my maternal lineage was not European. I’m sure, however, that my surprise was nothing compared to that of two British women who recently discovered that their maternal lineage was of Native American descent (the original article is available through the BBC).
Doreen Isherwood and Anne Hall learned that their mtDNA belonged to Haplogroups A and C, traditional Native American Haplogroups. As the BBC story explains, Native Americans were brought back to England as early as the 1500s.
Said Ms. Hall: “I was thrilled to bits. It was a very pleasant surprise. To have Native American blood is very exotic.”
Yesterday Science published a report from deCODE genetics in Iceland and a second report from academic colleagues in the United States and Canada that announced the discovery of a gene variant (a SNP) on chromosome 9p21 that results in an increased risk of heart attack (the abstracts are available online here and here). The SNP was discovered through genome-wide SNP analysis in Iceland and replicated in three groups of European descent in the United States. I don’t have access to either paper, but according to deCODE’s press release the variant is estimated to account for 20% of the incidence of heart attacks in Europeans, including one-third of early-onset cases (men and women age 50 to 60). Both companies used SNP Chips (that’s fun to say outloud), tiny gene chips that contain thousands and thousands of SNPs across the entire genome. Want to learn more about SNPs? Go to the SNP information page at the Human Genome Project.
Last week I posted Ten Videos for Genetic Genealogists, a collection of YouTube and other videos that might be of use to people who are just starting out in the field of genetic genealogy (and hopefully many others!).
Another valuable (and ever-growing) resource for genetic genealogists (indeed, for ALL genealogists, is Roots TelevisionTM.Â Roots Television is an online media presentation website created by historian Megan Smolenyak Smolenyak and media producer Marcy Brown.Â The site offers a wide variety of programming on such topics as genetic genealogy, Irish roots, and African roots, as well as recordings of presentations by some of the world’s leading genealogists (to name only a few).
Roots TelevisionTM introduces themselves with the following:
Update: The podcast was updated to add the last 5 minutes of the interview (after the commercial break).Â As a result, the link to the podcast changed.Â I apologize to everyone who tried the old link – it should work fine now.
Market News First, a website dedicated to microcap markets, recently interviewed the CEO of DNAPrint Genomics, Inc.”Richard Gabriel, President and CEO of DNAPrint Genomics, Inc. spoke with MN1.com’s Rich Hancock on April 26th, 2007 about the Company’s innovative and cutting edge technology that aids law enforcement crime scene investigation (CSI) forensics, consumer applications in genealogy ancestry/genetic testing and its pharmaceutical and diagnostic applications. Mr. Gabriel highlights the Company’s recent advances in its pharmaceutical and diagnostic, and talks about its successes in both law enforcement and the growth market of DNAPrint’s consumer oriented products.”
1.Who is GINA?
GINA isnâ€™t a â€˜whoâ€™, itâ€™s a â€˜whatâ€™.GINA stands for Genetic Information Non-Discrimination Act.
2.Okay, what is the Genetic Information Non-Discrimination Act?
GINA aims to protect individuals in a variety of different areas.The legislation would prohibit access to genetic information by insurance companies and would prohibit insurance companies from discriminating against an applicant based on genetic information, the refusal to submit genetic information, or for have been genetically tested in the past.Additionally, the Act would prohibit employers from using or collecting genetic information to make employment decisions. The Act also establishes a Genetic Nondiscrimination Study Commission that is charged with reviewing new developments in the field of genetics and advising Congress.
I was unaware that today is actually DNA day.Â Learn more here.
“National DNA Day is a unique day where students, teachers and the public can learn more about genetics and genomics! It was created to commemorate the completion of the Human Genome Project in April 2003, and the discovery of DNA’s double helix.
Students and teachers nationwide can celebrate DNA Day and learn more about genetics and genomics through the National DNA Day activities available on these pages. NHGRI offers an online chatroom, a library of webcasts featuring genomic researchers, interactive teaching tools and an opportunity through our Ambassador program to invite a real-life genomic researcher to talk to your students.”
