• An analysis of all your genes
• Looks for mutations & differences in your genome
• Like taking all current and future genetic tests simultaneously
• A Human Genome Project performed on YOU
What is a Personal Genome Sequence?

Why get genetic testing?Ideas for more tests and interventions if I
learn I’m at risk
To find the right drugs, in the right
doses, for my conditions
Motivation to change my
habits
Might reveal details of my family tree and genealogy
Planning for my long term medical and financial needs
I am an early adopter and
information altruist
I want to use my genome as a social
networking tool
To inform my reproductive decisions

– Predictive testing • Am I at risk for a genetic disease?
– Diagnostic testing • Does my disease have a genetic basis?
– Carrier testing • Might I pass on a genetic mutation to a potential
child?– Prenatal testing
• What can I learn about the genetic profile of my fetus?

• Order kit• Spit into a tube• Send tube back• Company puts your DNA sample on a chip• “science” occurs• Report mailed back to you; may only be raw

– Personal genome API– FDA clearance
• Navigenics: clinically guided genetic analysis– Bought out by Life Technologies
• Pathway Genomics: The Value of Knowing– Must be ordered through a U.S. physician registered

3. Evidence of a valid gene-disease association
4. Appropriately qualified staff to interpret the test result
5. Consumer protection legislation to prevent false or misleading claimsRegulating direct-to-consumer genetic tests: What is all the fuss about?Wright CF, Hall A, Zimmern RL.Genet Med. 2010 Oct 1. [Epub ahead of print] PMID: 20921893

• Predictive
– Use patient’s genome to determine probability of developing certain diseases
• Preventive– Based on individual risk profile, start
therapies in advance to reduce likelihood of illness
• Personalized– Create drug therapies to suit each genome
• Participatory– Patients will maintain own health by
learning about their predispositions

• HER2 oncogene • Over-expressed in 25-30% patients• Results in increase in replication of cancer
cells• Treat w/Herceptin, a monoclonal antibody that
inhibits HER2
BENEFITS– Herceptin targets ONLY cancerous cells, thus
eliminating need to administer large drug doses– Identification of ONLY patients w/gene over-
expression, thus preventing unnecessary treatments
Example—breast cancer

ChallengesWhat are the
privacy concerns for individual and families?
How much should we fear
discrimination at work and with
insurance?
How far ahead is the technology of its
clinical usefulness?
Will fair weight given to
environmental & social factors?
How can we ensure access for all who want to be
sequenced?
What surprises and secrets might
be revealed?
How realistic are promises of
anonymity?

GINA: Genetic Information Non-discrimination Act

“ The first civil rights legislation
of the 21st century”
-Senator Ted Kennedy
Signed 28 May 2008
(After 13 years of debate.)
![Page 43: Personal Genomics, Personalized Medicine, & YOU](https://reader030.vdocuments.site/reader030/viewer/2022033022/5681635b550346895dd41cce/html5/thumbnails/43.jpg)
GINA: Prohibits genetic discrimination in health insurance & employment
personal genetics education project (link)
Title 1: Prohibits discrimination in group and individual health insurance plans. Forbids genetic information being used to deny coverage, adjust premiums, or require someone to take a genetic test.
Title 2: Prohibits employers from using genetic information to make hiring, firing or promotion decisions. Severely limits employers rights to request, require, or purchase an employee’s genetic information.

• Method to test for certain genetic traits in an
embryo
• Embryo is created via in vitro fertilization
• Genetic testing occurs when embryo is 2-4 days old, typically at the 8-cell stage
• A single cell is removed and tested
• Results of testing are used to decide which embryos to implant in prospective mother’s uterus
