Navigenics: What my genome tells me to do

A few months ago, Navigenics.com offered me to analyze my saliva sample and genome. I happily accepted the offer and was curious to see what they could tell me. After graduating from medical school, I will start PhD training in personalized genetics this September so I’m quite into this emerging field of medicine.

I sent my saliva sample back to their laboratory this January and received the results in about 3-4 weeks.

I clicked on View my results and saw what kind of risks I have for certain medical conditions such as glaucoma, heart disease, prostate cancer, Crohn’s disease or osteoarthritis (9 conditions all together).

When I check one medical condition, I see something like that:

navigenics-results1

They tell me my risk compared to the whole population.

And how that medical condition is affected by environmental and genetic factors.

And if I’m interested in the particular single nucleotide polymorphism they analyzed, I can check the details.

Pros:

  • The information this service provided me with was useful and I will change some things in my lifestyle.
  • I can talk with a genetic counselor to discuss the results of my genetic variations.
  • I can print the results and share it with my doctor through an understandable report that mentions the references on which they based my risk percentages.
  • They help me what I can do in order to lower my risks for specific conditions. They also let me know things that prevent multiple conditions on the Navigenics panels.
  • Each condition is covered in details (causes, symptoms, treatments, etc.). This information is powered by Mayo Clinic.
  • I can find support groups or more information on prevention.

Cons:

  • Let’s say 3 SNPs tell me I have elevated risk for heart disease. But next year, they will discover 4 new ones that defend me from this condition. So Navigenics, just like any other similar companies, can only tell me risk percentages that might change a lot in the future.
  • For example, if based on my genomic results, I have elevated risk for heart disease, what I can do to lower this risk? Exercises, healthy lifestyle, etc. Things you can tell me without analyzing my genome. Though it’s not the fault of the service, but of the state genetics is in at the moment.
  • It’s still way too expensive compared to what I get for my money as the results cannot really be used for medical decisions  (I got a free package so I know I shouldn’t say that).
  • Well, a few genetic tests can be useful when making medical decisions, but such tests should be ordered only by medical professionals. Or if not, at least genetic counseling should be for free as patients need serious guidance when reading the results of their genomic variations. (Update: Navigenics provides free genetic counseling for all Health Compass members and 1 hour of free counseling for all Insight members. And you can order the tests through a medical professional or on your own.)
  • I think I can handle many things but it was almost impossible for me to understand which documents I have to send back to the lab with my saliva sample. A step-by-step video tutorial would be useful.

I’m thankful to the Team of Navigenics.com for showing me how their service works in action. I’m impressed and looking forward to seeing how they can make their service even better.

Navigenics Interview: Annual Insight

In my post about the predictions for 2009 in genomics, I said Navigenics would rule the market even if its service was more expensive than the kit of 23andMe. Now I had a chance to do an interview about the scientific background of the service and I have already sent my saliva sample back to their lab so the results should arrive soon.

Now, they came up with a totally new website, a new product and a lower price (read the press release). I’m always saying such genetic tests should be ordered by physicians. Well, here is an excerpt from the press release:

Accessible through Navigenics’ website, the secure portal empowers physicians with a suite of tools including a single access point to all of their participating patients’ genomic information, along with learning tools and case studies for integrating genomic information into their clinical practice.

I believe that was a crucial step to make.

1. There are more and more companies offering direct-to-consumer DNA testing. How does Navigenics try to make a difference?

  • Navigenics focuses exclusively on providing genetic information for health conditions – all of which can be delayed, prevented or diagnosed early.
  • We offer two DNA testing experiences that provide different levels of premium analysis and service to best meet your needs. With both, you’ll get relevant health information and the support to help you share your results with your doctor effectively.
  • We are the only personalized genetic testing company that provides the support of board-certified genetic
  • ounselors, to help you understand your results and take action.
  • We use only government-certified laboratories.
  • Our results are based on science of the highest possible caliber. We only report on genetic markers that have met stringent criteria developed by our team of Ph.D. geneticists.
  • Privacy is our priority. Your results are kept private and secure, so the only person who has access to your results is you.
  • Navigenics is committed to research and we serve as a leader and collaborator to advance the science of genetics. We collaborate with some of the best medical institutions in the world.

2. So far, the terms of service of Navigenics have stated the results shouldn’t be used for healthcare decisions. Will it change in the near future?

Our Terms and Conditions indicate that our services are not intended to substitute for professional medical advice, diagnosis or treatment, and we have always encouraged customers to work with their physician before taking any steps after receiving their Navigenics results. As our service offerings evolve and more physicians incorporate our services into their practice, we will consider whether that necessitates any changes or clarifications to our Terms and Conditions of service .

3. The new Annual Insight provides a genetic check up for 9 common medical conditions. Personalized genetic services usually analyze more than 20 conditions. What is the reason behind the decision to analyze only 9?

The Navigenics Annual Insight service offers a highly focused snapshot of your genetic predisposition to nine select health conditions. We use a customized test for each marker in order to gather 100% of the genetic information needed to give you a highly targeted analysis of your risk information for those health conditions . By focusing on 10 common conditions, you get a targeted look at some of the most common causes of disease and disability in the U.S. today.

4. What is the genetic background of the analysis? Do you use SNP chips to determine personal risks?

I have attached a detailed white paper that addresses this – please review and let me know if you have further questions. (Access to the pdf file: Applying Preventive Genomic Medicine in Clinical Practice)

5. How accurate do you think SNP analysis is nowadays? Of course, as science is moving forward, it can change, but do you think patients understand the scientific background? Can they make health decisions based on SNP studies?

Again, we encourage our customers to work with their physician before making any changes in their healthcare strategy after they receive their Navigenics results.

6. Are you open to use the tools of telemedicine or patients will have to meet genetic counselors in person? How do you ensure security?

Currently our genetic counseling sessions are conducted by phone. We have found this to be an effective and convenient means of providing professional support to those who engage in our testing services.

Navigenics adheres to rigid security standards throughout the genetic testing process. All of our Genetic Counselors are board-certified professionals who adhere to a code of ethics that includes maintaining the highest levels of privacy and confidentiality.

Navigenics is committed to protecting your privacy. You own your genetic data, and it is our responsibility to safeguard your genetic information. Using the most advanced data protection systems available, we:

  • Anonymize all member profiles to assure data security
  • Capture the minimum account information necessary for transactions.
  • Encrypt all your personal genomic data
  • Generate your genetic risk assessment reports on demand so they exist only as you view them
  • Maintain multiple layers of physical and electronic security measures.
  • Constantly monitor all relevant processes to ensure your genetic test results are not compromised
  • Have our operational, infrastructure and applications procedures independently audited.
  • Have a sophisticated customer identification process and authenticate all transactions.

Thank you for the answers!

What I especially liked on the new portal is the Genetic testing: Myths and truths section.
