Understanding Your Personal and Genomic Health: An Interview with Genome Medical

A few months ago, we partnered with Genome Medical to offer our members access to their network of clinical genomic specialists to better understand their personal health and DNA information.

Today, we’re chatting with Sheryl Walker, MS CGC to take a deeper look into the services they offer and how understanding your genetic makeup can help kickstart your health journey.


LunaPBC: Hi Sheryl Walker, MS CGC. Thanks for taking the time to chat with us today and share more about the amazing work you’re doing at Genome Medical. We’re excited to be partnering with you. In a nutshell, can you tell us more about Genome Medical and the services you offer to LunaDNA members?

Sheryl Walker, MS CGC, Genome Medical

Genome Medical: No problem, thank you for the opportunity! Genome Medical provides genetic counseling services by phone or video to individuals in all 50 states and has professionals with expertise in multiple areas of clinical care, including cancer, cardiology, reproductive, pediatric, pharmacy, and proactive genetic testing. LunaDNA members can schedule a one-on-one genetic counseling session for any of these areas to review their personal medical history and family medical history, discuss any appropriate diagnostic genetic testing, and gain answers to any specific questions they may have regarding their previous results. Diagnostic genetic testing can be useful and informative for an individual with a diagnosis as results could guide treatment, aid in recommendations for future care, provide risk information for relatives, and more.


LunaPBC: That’s wonderful. This is clearly highly beneficial for someone who may be experiencing health challenges. They’re able to learn so much about themselves and, more importantly, take adequate preventative measures to support them on their health journey. What if someone isn’t undergoing any health challenges? How might they still benefit from speaking with a genetic counselor?

Genome Medical: That is an excellent question. As researchers continue to learn about how our genes impact our health and potential for disease, and as more consumers learn about the information their genes can provide, more individuals are seeking genetic information–including those who are healthy and unaffected (no diagnosis). While a person may not currently have a diagnosis, testing of their genes could reveal risk and the potential for a future diagnosis. Many genetic diseases present earlier in life or family members will show signs/symptoms of a genetic disease that is being passed through a family–but this is not always the case as many factors influence the manifestation of disease, including environment, lifestyle, age, and genetic factors. Even individuals who currently have a clean bill of health could have a risk for hereditary disease based on their family medical history, or be found to have a genetic predisposition to disease that may not show signs on typically recommended health screenings (such as a predisposition to hypertrophic cardiomyopathy, a hereditary disease that causes thickening of the heart muscle–this would not be identified unless a person was undergoing specific cardiovascular screening/imaging). For several hereditary disorders, such as genetic predisposition to cancer risk, there are recommended screenings and management guidelines to help prevent a diagnosis and reduce risk. All individuals can benefit from reviewing their personal and family medical history with a genetic counselor, and even individuals who have no ‘red flags’ may be interested in and potentially benefit from clinical genetic testing (proactive healthy screening).


LunaPBC: Last year, we commissioned the Harris Poll to conduct a survey across 2,000 Americans to better understand the relationship Americans have with DNA test kits, including how informed they feel about how their DNA data will be used and general concerns with participation. We learned that roughly a quarter of Americans are concerned about finding out they carry a genetic disease (24%) and that their insurance company could access their results (23%). What would you say to the population of people who have these concerns?

Genome Medical: As a genetic counselor, I feel strongly that genetic testing can be extremely beneficial, but also that genetic testing is a personal choice. I have found that patients will choose to learn information about genetic testing at different times (not interested in their 30’s but become interested in their 40’s), and desire different amounts of genetic information (more versus less genes analyzed), so the discussion we have in their session helps determine how they want to proceed and what is going to be most beneficial for them. I think it is good to question one’s motivations for accessing genetic information, but even more important to think about how one might use this information and feel learning they carry a genetic predisposition/disease. Genetic testing does not change what does/does not exist already in our DNA, but certainly changes our awareness of predisposition/risk.

I often hear concerns about privacy and access to genetic information. Regardless of how genetic testing is being facilitated (through a research study, a direct-to-consumer laboratory, or a diagnostic laboratory), it is important to know how your information and data are handled/stored, and know what legal protections exist in relation to genetic information. The Genetic Information Non-Discrimination Act (enacted in 2008) protects individuals from discrimination based on genetic test results in regards to their health insurance and employment, in addition some states have additional protections. However, the federal protections do not extend to private life insurance, disability insurance, or long-term care insurance . More information on this federal law can be found here: GINAhelp.org. Genetic counselors discuss this information during appointments as it can impact decision-making about genetic testing.

The role of the genetic counselor is to help navigate these issues and decisions and explain risks and testing in an accessible way. Genome Medical is proud to be able to provide this type of precision medicine care in a convenient and affordable way to their patients.


LunaPBC: Knowledge is truly power. We often get asked, why would I use Genome Medical’s services when I can order a test on my own through companies like 23andme and AncestryDNA?’ as I’m sure you do, too. How do you best answer that?

Genome Medical: While there are now many different direct-to-consumer (DTC) genetic tests now available that a person can order themselves, diagnostic genetic testing can only be ordered by healthcare professionals (like the genetic counselors and geneticists at Genome Medical). The testing performed by DTC companies typically uses SNP (single nucleotide polymorphism) analysis, that looks at predetermined sites in your genes, whereas a lot of diagnostic genetic testing is performed using next-generation sequencing, which looks at each and every site in the genes. You can think of it this way: if one of your genes was a book, SNP analysis is like reading a single page, whereas next-generation sequencing reads the entire book cover to cover. DTC testing does not typically take into account personal medical history or family medical history. Genetic counselors use this information along with diagnostic genetic testing to provide information about risk and recommended management of risk. Most DTC companies report extremely limited (if any) information on inherited cancer risk, and any finding (whether cancer risk-related or otherwise) reported on the formal test report or found through analysis of raw data absolutely needs to be confirmed through diagnostic genetic testing before making any changes to medical care. If an individual has a strong family history of cancer or cardiovascular disease, they should seek genetic counseling and diagnostic genetic testing.


LunaPBC: So, in short, there’s a big difference. Good to know. As we can imagine, your clinical team of 40+ medical geneticists, genetic counselors, primary care doctors, pharmacists and other specialists who can provide medical services in all 50 states puts you at such a great advantage to reach a wide network of people and at a quick rate. How soon can a member speak with one of your Genetic Counselors once they become interested?

Genome Medical: Appointments are convenient since we can see patients through phone or video, so interested members can typically speak with a genetic counselor within 24-48 hours (limited weekend appointments are available).


LunaPBC: This all sounds great—why wouldn’t anyone want to jump on this great opportunity? Is there anything else that may be important for our members to know that we may not have already covered?

Genome Medical: As I mentioned above, I think everyone can benefit from a thorough discussion of their personal and medical family history. However, it is important to recognize that, like other areas of medicine, genetics is subdivided into different specialties. The genetic counselors at Genome Medical have different areas of expertise, so if an individual is interested in learning more about cancer risk AND discussing inherited cardiovascular diseases, this may be best addressed in two separate appointments. In order for our genetic counselors to best tailor your session to fit your specific needs, it always helps to have as much information as possible before your scheduled appointment (this can include filling out our survey and indicating specific questions you want to address and uploading previous genetic test results to our portal for review). Our medical practice is driven by our desire to provide the best genetic healthcare experience possible. We look forward to hearing from your members!


LunaPBC: Thanks for taking the time to chat with us, Sheryl Walker, MS CGC, and for supporting us to encourage our members to take control of their health and their data.
