The Health section of the 23andMe site is where you can learn about how your genetics relate to:
- Passing on an inherited condition (such as Cystic Fibrosis or Tay-Sachs Disease)
- Genetic risk factors for certain complex diseases (such as Late-onset Alzheimer’s Disease)
- Your response to certain medications (such as Warfarin Sensitivity)
- Your genetic traits (such as are you likely to be lactose intolerant or are you a fast or slow caffeine metabolizer)
Keep in mind that many conditions and traits are influenced by multiple factors including personal and family history, other genes, and the environment. Our reports are intended for informational purposes only and do not diagnose any disease.
Some reports are considered sensitive in nature; these reports require an additional opt-in regardless of whether or not a variant associated with that condition is present. When viewing an opt-in report, you must first view a disclaimer prior to unlocking each report. Once you have opted in to view the information, you will not have the ability to hide, or lock, the individual report. You can, however, opt out of seeing all of the health-related and trait reports at anytime from within your Account Settings.
The reports in the Inherited Conditions section tell you if you have genetic variants that have been linked to recessive conditions. In general, recessive conditions typically occur when a person has two variants for that condition, one inherited from each parent. A person with just one variant for these conditions is known as a carrier. Carriers do not have the condition, but they can pass the variant to their children. If both partners are carriers for the same inherited condition, they may have a child with the condition.
These reports include only a subset of possible variants that may be linked to a condition. Thus, it is possible to be a carrier for other variants not included in these reports. If you have a family history of any of these conditions and are thinking about having children, you should discuss options for testing with your doctor or a genetic counselor.
The reports in the Genetic Risk Factors section tell you if you have genetic variants that are risk factors for various complex health conditions - such as Late-Onset Alzheimer's Disease or Parkinson's Disease. While having a particular variant can be linked to a higher risk for a condition, it does not necessarily mean you will develop the condition. It is important to remember that these reports do not cover all possible genetic variants that could influence risk for these conditions and that other non-genetic factors, such as environment and lifestyle, can also influence risk for these conditions.
Reports thought to be sensitive in nature require an additional step before you can view your result. Everyone, regardless of whether or not they have a variant associated with that condition, must view a disclaimer prior to unlocking each report. Learn more.
The reports in the Drug Response section provide information about how you may respond to various drugs based on specific genetic variants. These reports may tell you how effective a drug may be, how sensitive you may be to a drug, or how likely you are to have certain side effects based on your genetics.
The information in these reports should not be used independently to determine or adjust any treatment plan. Many factors besides the variants covered in these reports can influence how a person responds to a drug. Do not stop, start or change a drug regimen without consulting a doctor.
The reports in the Traits section tell you about genetic variants that may influence different non-health related and wellness traits. Keep in mind that many traits are influenced by multiple factors. Traits may be influenced to varying degrees by genetics and the environment. This category includes noticeable traits like eye colour as well as subtle traits like the ability to taste certain bitter flavors.
These reports describe study findings observed in groups of people. The findings may not be representative of individuals and may not be applicable to all ethnic backgrounds or sexes depending on the trait. Many of the genetic variants reported are associated with normal variation and may have small effects on the trait. Many factors besides those described in the report, both genetic and non-genetic, may also influence the trait.
