*The 23andMe PGS test uses qualitative genotyping to detect clinically relevant variants in the genomic DNA of adults
from saliva collected using an FDA-cleared collection device (Oragene·DX model OGD-500.001) for the purpose of
reporting and interpreting genetic health risks and reporting carrier status. It is not intended to diagnose any
disease. The relevance of each report varies based on ethnicity. Each genetic health risk report describes if a
person has variants associated with a higher risk of developing a disease, but does not describe a person's overall
risk of developing the disease. These reports are not intended to tell you anything about your current state of
health, or to be used to make medical decisions, including whether or not you should take a medication or how much of
a medication you should take. Our carrier status reports can be used to determine carrier status, but cannot
determine if you have two copies of any genetic variant. These carrier reports are not intended to tell you anything
about your risk for developing a disease in the future or anything about the health of your fetus, or your newborn
child's risk of developing a particular disease later in life. For Gaucher Disease Type 1, we provide a single report
that includes information on both carrier status and genetic health risk.
The Parkinson's Disease genetic health risk report (i) is indicated for reporting of the G2019S variant in the LRRK2
gene, and the N370S variant in the GBA gene, (ii) describes if a person has variants associated with an increased risk
of developing Parkinson's disease, and (iii) is most relevant for people of European, Ashkenazi Jewish, and North
African Berber descent.

23andMe Genetic Health Risk Reports:
What you should know
Genetic Health Risk reports tell you about genetic variants associated with increased risk for
certain health conditions. Not all genetic variants that may affect your risk are included.
Having a risk variant does not mean you will definitely develop a health condition. Many people with an
increased risk never develop the condition.
Other factors like lifestyle and environment can affect whether a person develops the condition. Our
reports cannot tell you about your overall risk and they do not diagnose any health conditions.
Genetic counseling can help you understand your results and options. It is
recommended before testing, and if you have a risk variant.
Should you speak to a genetic counselor?
Should you speak to a genetic counselor?
We encourage you to learn more so you can decide whether testing is right
for you. A genetic counselor, a healthcare professional with special
training in genetic conditions, will be able to answer your specific
questions and help you make an informed decision.
Genetic counselors can help you navigate common questions, such as:
What are the risks and benefits of genetic testing?
Are there diseases that run in the family?
How do you handle potentially distressing information?
What are you hoping to find out from genetic testing?

Possible test results
Variant(s) not detected
You do not have the variant(s) we tested. Other genetic and non-genetic factors may affect your risk.
Variant(s) detected
You have one or more of the variants we tested. You may be at increased risk for the condition based on this
result. This doesn't mean you will definitely develop the condition. Other factors may also affect your risk.
Result not determined
Your test result could not be determined. This can be caused by random test error or other factors that
interfere with the test.
What to do with the results
If your report says you have variants associated with increased risk
Consider sharing the result with a healthcare professional.
Consider sharing your results with relatives. They may also have these variants. Keep in mind that some people may not want to know information about genetic health risks.
Concerned about your risk?
If you have other risk factors for the condition, you should discuss the condition with a doctor.
You can also discuss your results with a
genetic counselor (this link takes you to a page managed by the National Society of

What to know about our Genetic Health Risk reports
What to know about: Age-Related Macular Degenerationand our test
Age-related macular degeneration (AMD) is the most common cause of irreversible vision loss among older adults. The disease results in damage to the central part of the retina (the macula), impairing vision needed for reading, driving, or even recognizing faces. This test includes the two most common variants associated with an increased risk of developing the condition.
Typical signs and symptoms
Blurred or distorted vision
Vision loss
Yellow fatty deposits in the retina called "drusen"
Blood or fluid leakage in the retina
Other factors that influence risk
Smoking
Age
Family history
Ethnicity
Diet
When symptoms develop
AMD is rarely diagnosed in people under the age of 50. Vision loss related to AMD usually becomes noticeable in a person's 60s or 70s and tends to worsen over time.
How it's treated
There is currently no known prevention or cure for AMD. Having regular eye exams can help detect early signs of the condition. Progression of AMD can be slowed with the use of certain treatments and medications.
What do we test?
Tests for the Y402H variant in the CFH gene and the A69S variant in the ARMS2 gene associated with an increased risk of developing AMD.
Genetic testing for AMD is not currently recommended by any healthcare professional organizations.
Relevant ethnicities
The variants included in this test are common in many ethnicities, but are best studied in people of European descent.
Test performance summary
Accuracy was determined by comparing results from this test with results from sequencing. All test results were correct. While unlikely, this test may provide false positive or false negative results. For more details on the analytical performance of this test, refer to the package insert.
What to know about: Alpha-1 Antitrypsin Deficiencyand our test
AAT deficiency is a genetic condition that can lead to lung and liver disease. It is caused by decreased levels of the alpha-1 antitrypsin (AAT) protein. This test includes the two most common variants linked to this deficiency.
Potential signs and symptoms of AAT deficiency
Shortness of breath and wheezing
Chronic cough
Recurrent lung infections
Lung disease, including emphysema
Liver disease, including cirrhosis
Other factors that increase risk
Genetic variants are the only risk factor for AAT deficiency. In people with
genetic risk variants, the chances of developing symptoms of AAT deficiency depend
on lifestyle, environment, and other factors.
Smoking
Occupational and other exposures
Personal or family history of lung disease
Viral infections
When symptoms develop
Because it is a genetic condition, AAT deficiency is present at birth. Symptoms of lung disease usually appear later in life, and age of onset is strongly affected by smoking. Some people may never have symptoms of lung disease, especially if they don't smoke. Liver problems may develop anytime from infancy to adulthood.
How it's treated
There is currently no known cure. People with AAT deficiency are encouraged to avoid smoking and consider getting certain vaccinations. For those with symptoms, treatment focuses on management of lung and liver problems. Direct replacement of the AAT protein into the blood may be used to slow the progression of lung disease. Lung and liver transplants may be beneficial in some cases.
What do we test?
Tests for the PI*Z and PI*S variants in the SERPINA1 gene linked to AAT deficiency.
Testing for genetic variants associated with AAT deficiency is recommended under certain circumstances by several health professional organizations, including the American Thoracic Society.
Relevant ethnicities
The variants included in this test are most common and best studied in people of European descent.
Test performance summary
Accuracy was determined by comparing results from this test with results from sequencing for 409 samples. 409 out of 409 genotype results were correct. While unlikely, this test may provide false positive or false negative results.
What to know about: Hereditary Hemochromatosis (HFE-Related)and our test
Hereditary hemochromatosis is a genetic condition characterized by absorption of too much dietary iron. This may lead to iron overload, which can cause damage to the joints and certain organs, such as the liver, skin, heart, and pancreas. This test includes the two most common variants linked to this condition.
Typical signs and symptoms
Joint and abdominal pain
Fatigue and weakness
Darkening of the skin
Liver disease
Heart disease
Diabetes
Other factors that influence risk
Age
Sex
Alcohol consumption
Diet
When symptoms develop
Because it is a genetic condition, hereditary hemochromatosis is present at birth. Many people with this condition never develop iron overload. Of those who do develop iron overload, only a small number develop symptoms. If men develop symptoms, they typically appear between 40 and 60 years of age. Women rarely develop symptoms, and when they do it tends to be after menopause.
How it's treated
People with hereditary hemochromatosis are typically monitored for symptoms or complications. Iron overload related to hereditary hemochromatosis is a treatable condition. In some patients, having blood drawn on a regular basis can help lower iron levels. People with iron overload are encouraged to avoid drinking alcohol to minimize liver damage and to limit intake of iron-rich food.
What do we test?
Tests for the C282Y and the H63D variants in the HFE gene linked to hereditary hemochromatosis.
Genetic testing for hereditary hemochromatosis is recommended under certain circumstances by several health professional organizations, including the American Association for the Study of Liver Diseases and the European Association for the Study of the Liver.
Relevant ethnicities
The variants included in this test are best studied in people of European descent.
Test performance summary
Accuracy was determined by comparing results from this test with results from sequencing. All test results were correct. While unlikely, this test may provide false positive or false negative results. For more details on the analytical performance of this test, refer to the package insert.
What to know about: Hereditary Thrombophiliaand our test
Hereditary thrombophilia is a predisposition to developing harmful blood clots. These harmful blood clots most commonly form in the legs and can travel to the lungs. This test includes the two most common variants linked to hereditary thrombophilia.
Typical signs and symptoms of harmful blood clots
Pain, tenderness, swelling, or redness in one or both legs
Chest pain
Difficulty breathing
Hereditary thrombophilia may also be associated with recurrent late pregnancy loss in some women.
Other risk factors for harmful blood clots
Major surgery
Age
Prolonged immobility
Oral contraceptives
Obesity
When symptoms develop
Hereditary thrombophilia is genetic, but the risk of developing harmful blood clots increases with age and other factors.
How it's treated
Hereditary thrombophilia typically does not require any ongoing treatment. In some cases medications can be used to prevent harmful blood clots from forming. Medications and surgery can also be used to break up existing clots.
What do we test?
Tests for the Factor V Leiden variant in the F5 gene and the Prothrombin G20210A variant in the F2 gene linked to hereditary thrombophilia.
Testing for genetic variants associated with hereditary thrombophilia is recommended by ACMG under certain circumstances. This test includes the two variants recommended for testing by ACMG.
Relevant ethnicities
The variants included in this test are most common and best studied in people of European descent.
These variants are also found in populations with European ancestry, like African Americans and Hispanics or Latinos.
Test performance summary
Accuracy was determined by comparing results from this test with results from sequencing for 404 samples. 404 out of 404 genotype results were correct. While unlikely, this test may provide false positive or false negative results.
What to know about: Late-Onset Alzheimer's Diseaseand our test
Alzheimer's disease is characterized by memory loss, cognitive decline, and personality changes. Late-onset Alzheimer's disease is the most common form of Alzheimer's disease, developing after age 65. Many factors, including genetics, can influence a person's chances of developing the condition. This test includes the most common genetic variant associated with late-onset Alzheimer's disease.
Typical signs and symptoms
Memory loss that worsens over time
Mood and personality changes
Trouble planning or solving problems
Confusion with place or time
Difficulty performing daily life activities
Other factors that influence risk
Age
Sex
Family history
Heart health
Diet
Intellectual activity
When symptoms develop
Late-onset Alzheimer's disease develops after 65 years of age.
How it's treated
There is currently no known prevention or cure for Alzheimer's disease. Medication may be used to delay or ease symptoms.
What do we test?
Tests for the ε4 variant in the APOE gene associated with an increased risk of developing late-onset Alzheimer's disease.
This test does not identify or report on the ε2 and ε3 variants of the APOE gene. These variants are not associated with an increased risk of developing Alzheimer's disease.
Genetic testing for late-onset Alzheimer's disease is not currently recommended by any healthcare professional organizations.
Relevant ethnicities
The ε4 variant included in this test is found and has been studied in many ethnicities. Detailed risk estimates have been studied the most in people of European descent.
Test performance summary
Accuracy was determined by comparing results from this test with results from sequencing for 544 samples. 543 out of 544 genotype results were correct. While unlikely, this test may provide false positive or false negative results.
What to know about: Parkinson's Diseaseand our test

FDA Information
23andMe Carrier Status Tests:
What you should know
Carrier status tests detect genetic variants that can cause
inherited conditions. These variants are often
found primarily in certain ethnicities.
Being a carrier means you have one variant for the condition.
Carriers typically don't have the condition but can pass the variant to their
children.
Knowing your carrier status is important when having children.
If you and your partner are both carriers, you may have a child with the condition.
Genetic counseling can help you understand your results and
options. It is recommended before testing, and also if you are a carrier.
