FDA Approves Direct to Consumer Genetic Predisposition Test.

The U.S. Food and Drug Administration today allowed marketing of 23andMe Personal Genome Service Genetic Health Risk (GHR) tests for 10 diseases or conditions. These are the first direct-to-consumer (DTC) tests authorized by the FDA that provide information on an inidual’s genetic predisposition to certain medical diseases or conditions, which may help to make decisions about lifestyle choices or to inform discussions with a health care professional.

“Consumers can now have direct access to certain genetic risk information,”said Jeffrey Shuren, M.D., director of the FDA’s Center for Devices and Radiological Health. “But it is important that people understand that genetic risk is just one piece of the bigger puzzle, it does not mean they will or won’t ultimately develop a disease.”

The GHR tests are intended to provide genetic risk information to consumers, but the tests cannot determine a person’s overall risk of developing a disease or condition. In addition to the presence of certain genetic variants, there are many factors that contribute to the development of a health condition, including environmental and lifestyle factors.

The 23andMe GHR tests work by isolating DNA from a saliva sample, which is then tested for more than 500,000 genetic variants. The presence or absence of some of these variants is associated with an increased risk for developing any one of the following 10 diseases or conditions:

    •       Parkinson’s disease, a nervous system disorder impacting movement;
    •       Late-onset Alzheimer’s disease, a progressive brain disorder that destroys memory and thinking skills;
    •       Celiac disease, a disorder resulting in the inability to digest gluten;
    •       Alpha-1 antitrypsin deficiency, a disorder that raises the risk of lung and liver disease;
    •       Early-onset primary dystonia, a movement disorder involving involuntary muscle contractions and other uncontrolled movements;
    •       Factor XI deficiency, a blood clotting disorder;
    •       Gaucher disease type 1, an organ and tissue disorder;
    •       Glucose-6-Phosphate Dehydrogenase deficiency, also known as G6PD, a red blood cell condition;
    •       Hereditary hemochromatosis, an iron overload disorder; and
    •       Hereditary thrombophilia, a blood clot disorder.

In addition, the FDA intends to exempt additional 23andMe GHR tests from the FDA’s premarket review, and GHR tests from other makers may be exempt after submitting their first premarket notification. A proposed exemption of this kind would allow other, similar tests to enter the market as quickly as possible and in the least burdensome way, after a one-time FDA review.

The FDA requires the results of all DTC tests used for medical purposes be communicated in a way that consumers can understand and use. A user study showed that the 23andMe GHR tests’ instructions and reports were easy to follow and understand. The study indicated that people using the tests understood more than 90 percent of the information presented in the reports.

Risks associated with use of the 23andMe GHR tests include false positive findings, which can occur when a person receives a result indicating incorrectly that he or she has a certain genetic variant, and false negative findings that can occur when a user receives a result indicating incorrectly that he or she does not have a certain genetic variant. Results obtained from the tests should not be used for diagnosis or to inform treatment decisions. Users should consult a health care professional with questions or concerns about results.

OCC’s epidemiologist is closely monitoring the COVID-19 status and is actively issuing updates as they are available. The Centers for Disease Control and the World Health Organization are the most trusted sources online.  While the CDC has announced new mask protocols for vaccinated individuals, there will be no changes for our office protocols for patients, guests, and staff members as the announcement does not apply to hospitals or medical facilities. Masks are still a requirement for all patients, guests and staff at our facility.

Bariatric Surgery and the clash of two pandemics.   

Major metabolic and bariatric surgery Societies and colleges globally are now calling for the safe resumption of bariatric and metabolic surgery before the COVID-19 pandemic is declared over. 

The sooner bariatric surgery can be safely performed, the quicker obesity, type 2 diabetes, and other diseases can be reduced or resolved as they are not only chronic they are also progressive.  Obesity is also linked to more than 40 diseases including type 2 diabetes, hypertension, heart disease, stroke, sleep apnea, osteoarthritis, and at least 13 different types of cancer.

A recent statement from the ASMBS says “Before COVID-19 began, it was clear that patients with obesity were ‘safer through surgery.’ In the era of COVID-19, ‘safer through surgery’ for patients with obesity may prove to be even more important than before.” Obesity and Metabolic syndrome have been identified as an independent risk factor for adverse outcomes including death among COVID-19 patients.
