Explore Hereditary Thrombophilia and what your DNA can tell you
Genetics of Hereditary Thrombophilia
Hereditary thrombophilia is genetic. The two most common genetic variants (differences) linked to hereditary thrombophilia are found in two genes, called F5 and F2. These genes are important in the normal clotting process. But the F5 variant (sometimes called factor V Leiden) and the F2 variant increase the risk of developing blood clots that can block blood flow to certain parts of the body.
Other factors that may cause an increased likelihood of Hereditary thrombophilia
Other factors can increase the chances of developing harmful blood clots.
- Major surgery
- Age
- Long periods of not moving, such as long-distance travel or being bedridden
- Using oral contraceptives containing estrogen
- Obesity
- Family history of harmful blood clots
Consult with a healthcare professional before making any major lifestyle changes.
Harmful blood clots impact many people
It’s estimated that up to 100,000 people die in the U.S. each year from blood clots. That’s more than 250 people per day.
Are blood clots preventable?
Harmful blood clots can often be prevented. Understanding if you may be at increased risk and addressing risk factors that are within your control can lower the chances of developing these blood clots.
Find out if your genetics might increase your likelihood of developing Hereditary Thrombophilia
You can find out whether you may be at increased risk of developing harmful blood clots based on your genetics through 23andMe’s Hereditary Thrombophilia Genetic Health Risk report*. This report includes the two most common genetic variants linked to hereditary thrombophilia. The Hereditary Thrombophilia Genetic Health Risk report is available through the 23andMe Health + Ancestry Service.
Health + Ancestry Service
*The 23andMe PGS test uses qualitative genotyping to detect select clinically relevant variants in the genomic DNA of adults from saliva for the purpose of reporting and interpreting genetic health risks. It is not intended to diagnose any disease. Your ethnicity may affect the relevance of each report and how your genetic health risk results are interpreted. 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. The test is 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, how much of a medication you should take, or determine any treatment. The Hereditary Thrombophilia genetic health risk report is indicated for reporting of the Factor V Leiden variant in the F5 gene, and the Prothrombin G20210A variant in the F2 gene and describes if a person has variants associated with a higher risk of developing harmful blood clots. The variants included in this report 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.
