Free* genetic testing

*Covers cost of test only—excludes office visit, copay, sample collection, and any other related costs to participant.

If you suspect you may have a rare genetic disorder of obesity, genetic testing may provide useful information to you and your doctor. However, testing can be costly and is not always covered by insurance.

Rhythm Pharmaceuticals, a company dedicated to transforming care of those living with rare genetic disorders of obesity, is sponsoring the Uncovering Rare Obesity program to help address this need. The program, available in the United States, includes:

Am I eligible?

The program is designed for those affected by severe obesity who suspect there is more to their obesity than diet and lifestyle. Typically, this includes symptoms such as insatiable hunger, weight gain while on a restricted diet and exercise, and severe obesity early in life.

To qualify, you must be:

BMI can be used as a general measure of body fat determined by comparing height and weight. Adults can measure their BMI here. Parents or legal guardians can check the BMI for children and teens here.

Your doctor will help you determine if you are eligible and will order the test on your behalf.

A genetic test is only one factor your doctor may use to help determine a diagnosis. Your family history, personal health history, and exact symptoms will also be considered. Speak with your doctor to determine the best plan for you.

How does it work?

The process is simple:

  • 1.

    Speak with your doctor to determine if you are eligible. You can prepare for this conversation here.

  • 2.

    Your doctor must order the test. You can complete the test in his or her office (via an oral swab or blood test) or at home (via a saliva sample). Your sample is then sent to an independent laboratory, PreventionGenetics, for testing.

  • 3.

    The results from your test will be sent directly to your doctor approximately 3 weeks after your sample and completed information are received by the lab.

    If you have questions about taking the test or about your results, genetic counselors are available as part of the program. You may email to schedule 2 counseling sessions (one before the test and one after) as part of the program. (Participants may choose to have one, both, or none of the counseling sessions offered through the program.)
