We're delighted to welcome Hsien as a HealthNex guest blogger this week, especially as she has started a new publication -- EyeOnDNA -- on a topic that IBM considers critical in the advancement of electronic healthcare: the increasingly important role of genomics and DNA in society, medicine and culture. (In fact, its so important to IBM that we created the first Genetics Privacy policy for a major global company, and is a partner in the Genographic Project.) Now the U.S. Congress is taking up the issue to ensure that the privacy of genetic information can be protected, even as it becomes a more central fact in modern life.

The genome revolution is upon us. New reports of gene-disease associations pepper the news each day. DNA technology is advancing so fast there are rumors that sequencing a person's entire DNA sequence will eventually cost no more than $1,000. Are you ready to take advantage of all that DNA can offer? Here are top 10 ways DNA technology will change your life.
10. DNA makes you hip.
Pop culture references to DNA are rife. If you want to be "in,"
learn how to mention DNA in casual conversation. For some pointers,
read my weekly series - In Your
DNA.
9. DNA is an artistic influence.
DNA has inspired artists in many mediums, including knitters, quilters, sculptors,
and painters
. You can also have your DNA pattern made into home deco prints or
your actual DNA embedded into necklaces. For other fun ideas, check
out my list of cool
things to do with your DNA.
8. DNA brings you closer to your family.
Genealogy is one of the most popular hobbies in the US. And to
trace their family ancestry, more people are increasingly turning to
genetic testing. Many companies will help amateur genealogists match
their genetic sequence with others in the database so it's possible to
find long lost cousins and other family members using nothing more
than DNA. And, of course, paternity, maternity, and other family
relationship tests can prove the bonds that bind.
7. DNA is a lucrative career choice.
Prospects for careers that involve DNA analysis are excellent. For
anyone considering a career change or embarking on a new career, some
of the jobs with most potential include laboratory technician,
especially in forensic services, and genetic counselor.
6. DNA technology inspires other forms of useful tech.
As Jack mentioned in his
post about nanotechnology, the concept of DNA and strands of DNA
itself are being incorporated into a number of different medical
devices, such as DNA
sieves, nanoscale
films made of DNA and water-soluble polymer, and DNA
layers for coating organs to improve transplant success. The
elegance of DNA and the way it functions is a neverending source of
ideas.
5. Your DNA may soon be collected for government
databases.
It probably comes as no surprise that the DNA profiles of criminals
are stored in databases such as the Combined DNA Index
System (CODIS) maintained by the FBI. But did you know that in
some states and countries, even those people who were not convicted
and others who were only convicted of misdemeanors have their DNA
samples taken and stored as well? New York State is now considering a
proposal to collect DNA from people found guilty of crimes at the
misdemeanor level or higher, all prisoners, all parolees, everyone on
probation, and registered sex offendors. In the future, everyone's
DNA may be collected for a variety of "good" reasons, such as to
help with public health efforts, identification in case of missing
persons, natural disasters, and terrorist attacks. Quebec, Canada has
already begun sampling
DNA from the general population.
4. DNA may determine your eligibility for a job or
insurance coverage.
Although the Genetic
Information Nondiscrimination Act (GINA) passed the House in April
2007, not all countries believe that employers and insurance companies
should be prohibited from using genetic information to screen
candidates. Police recruits in Trinidad and Tobago, Australia, and the
UK may face DNA testing in the effort to stem corruption. I discuss
other ways in which genetic
information can "help" employers determine the most suitable applicant
for the job at Eye on DNA.
3. You can put your DNA to work in the privacy of your own
home.
The genetic testing market is becoming increasingly crowded as a
growing number of companies provide direct-to-consumer DNA testing.
This trend raised
the alarms of the General Accounting Office (GAO) last summer
especially in regards to nutrigenomics, a field that uses a person's
DNA profile to determine the ideal diet and nutritional supplements.
Other types of direct-to-consumer or at-home DNA tests include those
used for tracing ancestry or genealogy. And there are also companies
that provide medical genetic tests and genetic counseling.
(Disclosure: I recently joined
DNA Direct as a consultant.)
2. Because parents can preselect certain traits in their
children using preimplanation genetic diagnosis and other DNA
technology, our population demographics will also be
changing.
There will never come a day when we can select our future children
like fruit from the supermarket. (At least I hope not.) But, parents
can already use preimplantation genetic screening (PGD) to select
embryos that are free of the genes for diseases such as breast cancer,
colon cancer, Down's syndrome, cystic fibrosis, and a whole shopping
list of other genetic diseases. There is fear that parents are also
able to select the gender of their children by using at-home
gender prediction DNA tests as early as six weeks gestation.
1. DNA technology will make it possible for us to receive
personalized medical care that's tailored for us.
The best part about the genome revolution will be the development
of personalized medicine - the ability to select medical treatment
specific to each individual based on his or her genetic
predispositions. For example, there is tremendous waste, inaccuracy,
and even danger involved in determine the dosages of some drugs, such
as warfarin. A warfarin
sensitivity DNA test is already available that tests for
variations in the CYP2c9 and VKORC1 genes that determine a person's
sensitivity to warfarin via metabolism and anticoagulation processes,
respectively. Gene therapy is another goal of personalized medicine.
Targeted treatment that focuses on a specific gene mutation could help
prevent, alleviate, and even cure diseases.
As you can see from this top 10 list, DNA technology can and does affects our lives in almost every way. Most people's number one concern when it comes to DNA is privacy. People fear Big Brother and a world like the one depicted in Gattaca. When DNA sequencing becomes so cheap and easy to perform that we're all carrying DNA replicators in our pocket, it will be hard to stop anyone from grabbing a strand of hair or a used cup to do a little DNA testing of their own. On the other hand, once everyone understands that we all carry flawed DNA, perhaps it will cease to be a a subject of contention. Approached in a thoughtful way, DNA technology will make our generation and the ones following us healthy, wealthy, and wise.
After this long pamphlet on the wonders of genetic technologies, it is somehow surprising that you mention any kind of precaution at all. I believe and embrace the science itself with all the benefits that its developments might bring for the Society as a whole. However, I don't believe that if left to an unregulated market, the science will be use and "Approached in a thoughtful way". I am for open debates with public and experts on doubt, promises and directs benefits but also potential risks. Your blogs and multiple initiatives on the subject don't really leave any room for such a thing. Could you precise what you mean by "Approached in a thoughtful way"?

Hi Rachel! How've you been? You're right that I tend to be optimistic about humanity and our approach to DNA technology. The kinds of thoughtful discourse that I'm hoping for starts here, at EyeOnDNA.com, the DNA Network that I co-founded, and elsewhere. Long-time readers will know that I'm far from promoting the use of DNA tech to solve the world's problems. Those of us who are involved in communicating genetic technology have an important role - to encourage positive uses and educate against negative ones.

Rachel:
I think the risks and challenges of how genetic information may be used, or misused, are a central consideration. In fact, they are almost a given. And we will never get to the benefits if we don't factor in the risks.
