Are there any services like 23andme that are more strict when it comes to data privacy or that allow me complete ownership of the data? I would love this type of analysis even at a higher cost but I am scared of what might happen in the future to this data on me and children

I have used Nebula. Did a group buy of the kits with several friends to obfuscate shipping address. Signed up via a protonmail address, and accessed the site only through VPN. Then deleted my data after downloading all of it.

I believe it would be very difficult to tie my identity to my genome because of these steps.

That probably depends on the closest relatively of yours that they have in their database.

If you only have one sibling and they're in the database, you're probably boned no matter the precautions you take.

https://familytreedna.com. I used to work for them > 2 years ago.

1. Order a Family Finder kit. When you get the kit but before submitting your swab, sign up for the account but opt-out of _all_ matching services.

2. Send your swab in.

3. When you get your results in (~6 weeks usually), download your raw data from the website.

4. Call their support line and ask for your data to be deleted.

I've been burned too many times in the past to ever believe this line, even if the people at the company are well intentioned.

Nebula is mentioned below for full DNA sequencing. I've used them for my son.

As for analysis, you could try one of these.

Health care providers can order genetic testing to help discover how your body metabolizes tons of things.

I recently had it done and it illuminated an entire class of anti-depressant that has very little efficacy for me.

Those tests are so limited in scope, I would not bother.

I bought a kit on Amazon from a major provider. It was a Father’s Day promo. So it’s safe to assume at least half of purchases were gifts. And Amazon FBA does not share buyer data with the seller. Plus then I used all anonymous services, like junk email, VPN to sign up.

How does one figure this out using their DNA.txt file? Is there a Wiki for genes?

Promethease (1) is a great site for doing this. You upload a genome (which they promise to delete), and download an HTML interactive report. The report spans thousands of studies, and it will tell you about any rare genetic disorders or interesting findings.

The cost is about $18, one time, iirc.

Do not stop at Promethease! I have been doing this for myself and others for the last 10 years. Promethease is great but misses several SNPs that are included in the raw data that may have an impact. Some other helpful websites:

Take a look at this report.

The newsletter above is fantastic BTW.

Can't you drink one coffee in the morning?

Also would like a source on the 2X cardiac event risk, couldn't find that in the linked article. Big if true!

I have this genotype and if I have a mouthful of coffee at 8 am, I will be able to feel it at 1 AM the following morning.

The enzyme responsible is CYP1A2 if I understand correctly. Here is the paper I found that supports increased risk of a specific cardiac event to slow metabolizers. I'm not the most adept at reading medical papers so I can't verify if it claims the risk is doubled, but I think it's possible.

Coffee, CYP1A2 Genotype, and Risk of Myocardial Infarction Marilyn C. Cornelis, BSc; Ahmed El-Sohemy, PhD; Edmond K. Kabagambe, PhD; et al Hannia Campos, PhD JAMA. 2006;295(10):1135-1141. doi:10.1001/jama.295.10.1135

I did the same, but without any of the data here.

Quitting caffeine got rid of my anxiety nearly entirely and my sleep quality was noticeably better. Literally changed my life.

The 3 days of headaches were very bad. But worth it beyond anything for me.

Open to questions if you have them, though it may take a bit to respond.

I feel pretty bummed about these kinds of stories.

I quit coffee for all of January, and I felt absolutely no difference. When I started again in February, apart from the first coffee feeling a little gross, I again felt no difference.

I imagine that simply lowering the dose over a few weeks before quitting might help with the headaches, for anyone else who decides to give up caffeine.

Do your blood pressure problems gp away if you don't drink coffee? Have you blind tested this by getting someone to brew you something that may or may not be decaf?

CYP1A2 does not only metabolize caffeine, it is also involved in the metabolism of various endogenous substrates, including fatty acids, steroid hormones and vitamins.

Focusing only on caffeine metabolism is one of the pitfalls of 23andme's reports.

This gene change might mean you have higher cholesterol as well.

To see everything this gene does check here: https://www.uniprot.org/uniprotkb/P05177/entry

> This gene change might mean you have higher cholesterol as well.

I have C/C in 23andme like gp and experience same caffeine effects. I have high cholesterol despite being active, fit and good diet.

Would you know of any literature that might explain this in more layman terms. I had hard time reading the link you mentioned.

Did this help?

https://jamanetwork.com/journals/jama/fullarticle/202502

CYP1A2 also metabolizes cholesterol so caffeine will increase your heart attack risk.

And this is why genetics are crucial in understanding your dietary risks.

So for those that slowly metabolize caffeine, would it be prudent to take a statin?

Probably not. It might be that you need the cholesterol to produce more steroid hormones. Statins not only stop you from making cholesterol but also CoQ10 as well.

It would probably be best to keep a check on your oxidative stress because that is what most likely triggers heart disease, not just cholesterol alone.

> it actually takes caffeine 4X the time

I have C/C like you and feel effects of caffeine at night from 6 am coffee like you.

I am really curious about 4x and 2x risk. I didn't seem to find that info in the link you posted.
