Let's make a difference in Sarcoidosis research. Together.

This is a research study focused on better understanding the underlying genetic and environmental factors that contribute to sarcoidosis in individuals with African ancestry. The ultimate goal of this research is to improve the lives of people living with sarcoidosis through a potential treatment discovery. Your participation may increase the chances that any treatment that may be potentially developed for sarcoidosis which could benefit people of African descent.

Currently, the cause of sarcoidosis is unknown, but previous research suggests that there is a strong genetic component. The 23andMe online platform enables a large group of individuals to come together to provide valuable data to researchers. This research data includes genetic information (using DNA from saliva) and information about each participant's unique experiences (using responses from online surveys). Conducting research using this data may help to find better treatments for sarcoidosis, or similar conditions.

Our goal is to enroll 2,000 participants with African ancestry who have been diagnosed with sarcoidosis.

You can participate in this study if:

• You are over 18 years old and live in the United States
• You have been diagnosed with sarcoidosis
• You have African ancestry
• You are willing to provide a saliva sample for DNA testing
• You are willing to complete online surveys about your health history and your experience with sarcoidosis

If you have been diagnosed with sarcoidosis by a medical professional and you meet the other criteria listed above, you may be eligible to participate in this study.

1. Enroll and consent through the 23andMe website so you can contribute your genetic data and survey responses to the Representation in Sarcoidosis Research Study.
2. Respond to a short questionnaire to determine your eligibility to participate.
3. Provide a DNA sample (from your saliva) for genetic analysis, if you are eligible to participate. We will securely store this saliva sample/DNA in our laboratory.
4. Complete short online surveys about your health history and your experience with your condition when you enroll. We will then ask you to complete a short follow-up survey about sarcoidosis every six months for the next two years. Surveys will include questions about your general health history, diagnosis, treatment, symptoms, medications and family history. We will email you to let you know when to take these surveys, and may send reminders and call you if you haven not finished all of the available study surveys.

Being a 23andMe research participant means that you will agree to contribute your Genetic and Self-Reported Information for research purposes. There are many aspects to being a research participant. We have summarized the most important ones below. If you have more questions, you can contact us at sarcoidosis-representation@23andme.com.

Data summaries:

If you agree to the main 23andMe Research Consent Document, you are giving consent for 23andMe to include your Genetic and Self-Reported Information in data summaries we share with qualified third party researchers.

23andMe may share your de-identified data, which is bundled (or aggregated) with data from other research participants (so you cannot be easily identified), with qualified research collaborators for this study and potentially for other studies in the future. This research could cover many different topics studied by 23andMe and our research collaborators.

We encourage you to read this consent document carefully. For your records, you can print each of the consent documents or review them at any time by going to your account settings. If you have any questions, don't hesitate to reach out to us at sarcoidosis-representation@23andme.com.

What are the risks of being a research participant?

• Being a research participant means that 23andMe will collect and store your Genetic Information and Self-Reported Information (this includes survey answers you might feel are sensitive in nature), and securely transfer them to qualified research collaborators. Although 23andMe implements physical, technical, and administrative measures to prevent unauthorized access to or disclosure of your information, in the event of a data breach, your information may be compromised.
• Please refer to How do you protect the confidentiality of my data? for more information about this risk.
• If you choose to access the health, traits and ancestry reports resulting from your use of the 23andMe Service, you may learn information about yourself that you do not anticipate (e.g., that you are not related to a family member in the way you thought, surprising facts related to your ancestry, or that you could pass on an inherited genetic condition to your children). Your 23andMe reports are not intended to diagnose a disease, or tell you anything about your risk or likelihood for developing a disease in the future. Please contact a qualified medical provider if you have any questions or concerns about the results contained in your reports.
• Please refer to our Terms of Service and Privacy Statement for more details about the risks of being genotyped.

What are the benefits of being a research participant?

This is a new opportunity to participate in sarcoidosis genetics research. As a research participant, you:

• Could play a role in helping researchers understand the relationship between sarcoidosis and genetics.
• Will be kept informed of the discovery process as research advances.
• Will have the option to learn more about your genetic health and ancestry.

The Representation in Sarcoidosis Research Study includes surveys over a period of two years. As more people join the study and our research scientists start to look at the data, there may be an opportunity to participate in additional studies to enhance the research.

If there are any additional study or survey opportunities, we will let you know about them through your 23andMe account and/or email.

If a commercial product is developed as a result of findings from this research, rights to the commercial product will belong to 23andMe and their collaborators. You and your family will not receive any financial benefits or compensation from or have any rights in any developments, inventions or other discoveries that might come out of this research.

This is a research study focused on better understanding the underlying genetic and environmental factors that contribute to sarcoidosis in individuals with African ancestry. Currently, the cause of sarcoidosis is unknown, but previous research suggests that there may be a strong genetic component. As part of this study, 23andMe has collaborated with the Foundation for Sarcoidosis Research (FSR) and developed a townhall speaking to how genetics may play a role in sarcoidosis, as a rare disease. You can learn more about the FSR and their efforts to help support individuals diagnosed with sarcoidosis here. You can view our townhall recording here.

Existing customers are individuals who have been genotyped by 23andMe prior to joining the study, and we welcome them to complete surveys included in the Representation in Sarcoidosis Research Study. There is no need to complete the study enrollment process; you can get started now by taking the first sarcoidosis survey here.

However, please know that the product experience will not change as a result of an existing customer's participation in a study. For example, if an existing customer purchased the Ancestry Service, they will not gain access to the Health + Ancestry Service without purchasing an upgrade.

New customers have not yet participated in 23andMe’s services and have not had their saliva analyzed prior to enrolling in a study. If they enroll in this study and meet the eligibility criteria, new customers will receive the 23andMe® Health + Ancestry Service, including a DNA test kit, at no cost. Learn more about the 23andMe Health + Ancestry Service here and read important test information here.

23andMe®'s Personal Genetic Service offers over 150 personalized genetic reports on your health, traits and ancestry based on your DNA. You can learn more about this service at 23andMe.com.

If you are new to 23andMe, as part of your participation in this research study, you will receive complimentary access to 23andMe®'s Personal Genetic Service. Learn more about the 23andMe Health + Ancestry Service here and read important test information here.

If you are already a customer of 23andMe, you will not be eligible to receive an additional complimentary 23andMe®'s Personal Genetic Service kit.

You will continue to have access to your 23andMe account and will receive report updates as long as the genetic information referenced in those updates is generated from your original DNA sample. If a future feature or report relies on DNA results not included in your initial analysis, you may need to purchase a chip upgrade and/or subscription to access that feature or report. Any future upgrades beyond the current technology are not included as a benefit to participation.

If you consent to participate in the Representation in Sarcoidosis Research Study, 23andMe may share summaries of research results, which do not identify any particular individual, with qualified research collaborators and in scientific publications. When we publish research results or share results with collaborators, we only publish or share summary information that does not identify any particular individual.

You may withdraw your consent at any time from your Account Settings. If 23andMe shares your Genetic or Self-Reported Information with a qualified research partner prior to your withdrawal, any research involving your data that has already been performed or published prior to your withdrawal from 23andMe Research will not be reversed, undone, or withdrawn. Please refer to our Privacy Statement to learn more about our practices.

23andMe uses physical, technical, and administrative security measures to protect your information. We regularly review and improve our privacy and security practices to help ensure the safety of your information. These practices include, but are not limited to, the following:

• 23andMe research analyses are conducted with information that has been stripped of your identifying Registration Information (information you provide when you register your account, such as your name and contact information). Your contact information may be used to communicate with you but are not analyzed in combination with your Genetic and Self-Reported Information.
• When we publish research results or share results with collaborators, we only publish or share summary information that does not identify any particular individual.
• 23andMe maintains an internationally recognized security standards certification for our robust data privacy and security systems.
• All 23andMe employees are trained on how to work with human research participants, and 23andMe researchers receive additional training on how to conduct research responsibly.

We built all of our systems with the privacy and security of our research participants at the center and we have a number of safeguards in place to ensure confidentiality. All data in the research computing environment are disconnected from your contact or registration information and are coded with a unique research ID.

23andMe research scientists who have access to your Genetic or Self-Reported Information (i.e. DNA results, survey responses) do not have access to your Registration Information (i.e. account or contact information). Conversely, 23andMe project managers who have access to your contact information do not have access to your sensitive individual-level Genetic or Self-Reported Information. Thus, it would be extremely difficult for 23andMe employees or any external party to link your individually identifying information to your DNA results and survey response data.

Unfortunately, there are always unknown threats in information security. Therefore, we cannot fully guarantee the security of your data. However, we constantly update our security systems and protocols to deal with new threats as they become known. We protect against known factors by applying industry practices in all of our information security procedures.

All 23andMe Research is performed in a secure computing environment with access restricted to research scientists and system administrators. All 23andMe servers are protected by technical, physical, and administrative procedures. Our servers are monitored for unauthorized activity. Your genetic data and sensitive account information such as passwords are encrypted, as are all data transfers between our servers and your computer(s).

23andMe also has agreements with all research collaborators regarding the security and storage of data that is shared outside 23andMe. Although 23andMe cannot provide a 100% guarantee that your data will be safe, 23andMe policies and procedures minimize the chance that a breach could take place.
