I am not a medical health professional and any comments I post are not intended, nor should they be construed, as medical advice.
It’s important to understand that having markers is not a guarantee of getting a medical condition. I know people who never get a medical condition who have been tested with advanced DNA testing. Likewise, I know people who were tested with advanced DNA testing and showed no known markers for a medical condition who get the medical condition.
Update January 15, 2021 shortly after posting. Looks like they are ending Health kit sales some time today. I linked an article from GenomeWeb below showing more information.
I saw this morning on Bloomberg – Ancestry Pulling Health DNA Test Just Over a Year After Launch: https://www.bloomberg.com/news/articles/2021-01-14/ancestry-pulling-health-dna-test-just-over-a-year-after-launch. I noticed it was also verified by another blogger this afternoon – https://cruwys.blogspot.com/2021/01/ancestrydnas-health-test-is-to-be.html. When I checked after seeing Debbie‘s post, you can still order AncestryDNA Health on their website.
I saw this article – Ancestry to Discontinue NGS-Based AncestryHealth Service: https://www.genomeweb.com/sequencing/ancestry-discontinue-ngs-based-ancestryhealth-service and it indicates they will stop selling AncestryDNA Health kits today and will support users through July 2021.
My problem with the various health kits offered by 23andMe, AncestryDNA, and MyHeritageDNA is they don’t test enough markers. With BRCA cancer markers, there are over 1,000 known markers, but none of these companies test all of those markers. The companies test a fraction of the known markers and give you results based on the markers they test. Ideally, they would test all the known markers which could significantly raise the price of the Health test. On the plus side, this would give you a more reasonable likelihood to determine if you are at risk of getting cancer or any other medical condition.
In terms of DNA, it can play a part in determining if you get a specific moredical condition, but according to medical experts it is not the only factor in the equation – Just How Much Is Cancer Due to Your Genes? – Several Articles Covering 2016 to 2020. The links in the post indicate somewhere between 5% or possibly as high as 1/3 are genetics related.
