Although the project states that most participants won’t receive any useful information, patients will be told if something is found in their genome that is relevant to the treatment, explanation or diagnosis of their condition. They can also choose to learn if they have a genetic risk factor for another disease, such as the BRCA1 gene mutation that can cause breast cancer. Genomics England will only look for risk factors that are linked to a disease that can be treated or prevented. Untreatable conditions, such as Alzheimer’s, are not looked for.
Rachel, it’s been a year since you posted your query. Perhaps you have your answers? In case not, here are a few suggestions. Since you are an adoptee, perhaps with no knowledge of your biological family, you probably are most interested in details there, while your ethnic makeup is a very minor concern and where most DNA services give similar results anyways. Maybe your goal is to locate your birth parents? If that’s all true, then buy an AncestryDNA kit, as they have 10 million DNA profiles in their database, which is more than all competitors combined. The more profiles to DNA match against the more matches you’ll get to your biological relatives. Next download your raw Ancestry DNA data, and then upload it for free into MyHeritage (2.5 million DNA profiles), FamilyTreeDNA (1 million DNA profiles), GEDmatch (1 million DNA profiles), LivingDNA (unknown database size), and DNA.land (0.15 million DNA profiles). That’s almost 5 million more DNA profiles to match against. Combined with AncestryDNA that’s about 15 million profiles. If lucky you may match to a 2nd cousin or closer relative which with luck could lead to your birth parents, definitely will match to a few if not many 3rd cousins and 1000s of 4th or more distant cousins. If you change your mind and decide purchasing a second DNA kit is worth the expense, then buy a 23andMe DNA kit, which adds 5 million more DNA profiles to match against. Hope these suggestions were useful. Good luck.
23andMe started out by testing for genetic markers of diseases and medical conditions before rolling that back in response to the governmental concerns. It has since started slowly adding more health-related features with approval from the FDA. In April, 23andMe got approval to offer risk analysis for ten genetically linked diseases. The company now offers two options: Health + Ancestry ($199) and Ancestry ($99). The Health + Ancestry plan includes testing for genetic health risks and carrier status, as well as reports on your genetic weight, hair loss, and other traits.
When you get your 23andMe results, it takes you to an easy-to-navigate dashboard with your ancestry composition report front and center. Testers reported both high levels of confidence in the accuracy and high rates of satisfaction with the contents and detail of their results. The service breaks down the world into 171 populations, based off its reference panel of 10,000 individuals with known ancestry. Some of these population groups are a tad redundant. For example, I received hits for South Korean, Korean, Broadly Japanese & Korean, and Broadly East Asian in my report, which all represent a similar area but show different levels of certainty. Scrolling down your ancestry summary, you can also view your ancestry timeline. This estimates how many generations back your most recent ancestor from each of your matched regions probably lived. You can also view your ancestry composition mapped out on chromosomes. This view is interesting, as you can change the level of confidence from speculative to conservative, which equates a match percentage of 50 to 90 percent.
This is very interesting…thanks for sharing—regarding you husband’s results– the Somali 1% might not be so crazy at all—look at the map– horn of east Africa to Yemen area (had a large Jewish population long ago)…to Palestine-Israel…to Europe in the centuries long diaspora..actually your comments made me more inclined to try this newer company. I am grateful to you.
In addition to showing geographic ancestry percentages, some direct-to-consumer DNA tests also include insights about physical traits like hair and eye color. With 23andMe, this trait information is mostly available in the upgraded Ancestry + Health kit, but some interesting tidbits can be found in the Your DNA Family report, which is available if you opt to participate in the DNA Relatives service.
My daughter and I did 23andMe. Love them problem being, I was adopted and have been told all my life I have indian (Cherokee) in me. It showed nothing no indian in me. My daughters father side said they have Mohican and Italian it showed nothing for her. Is there another site that can help. I have talked with my bio family and they say my father had indian in him.
Written out the base pairs in DNA make a sequence, e.g. A T A T C G C G T A A T G C. More than 99.9% of those bases are the same in all people. The order, or sequence, of the letters determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences.
