If you want to say that the person who spat out the piece of gum you sequenced is female and European, yeah you can probably do that for $200.
My understanding is that what 23andme et al do is very far from actual full sequencing.
I have some variant of Marfan's syndrome but have not shown the associated heart problems. After consultation with a geneticist we concluded that I could spend a bunch of money to get the exact variant that I have of the relevant genes sequenced. But almost certainly I would learn that I have some variant of Marfan's syndrome that is not understood. Relatives who also have the same phenotype can get sequenced to verify that it is genetic. But since none of us are showing the most troublesome problems, and the literature almost certainly doesn't have our exact variation, I would learn nothing more than I know already.
So just get an MRI every 5 years, and wait for costs to come down and research to improve. In 10-15 years look again and maybe the genetic test will be useful then.
For a genetic condition as specific as mine, the sequencing done by these commercial providers is useless.
There are a few very well done genetic tests for a limited number of diseases.
This is the whole thing, raw data included. Not 23andme crap.
Edit: Dante seems to be doing the basic 30x full sequence for $229 at the moment.
and don't throw away/flush any biological material. in most jurisdictions, trash is public property. if someone really wants your DNA they can hunt through your garbage till they find a hair, flesh, blood, etc.
And the fact that you share so much of it with your family just compounds the problem with trying to keep DNA a secret.
I'd like my DNA to remain private but it's less realistic than keeping even your fingerprints private.
PCR in a phone? How novel.
This sort of nonsense belongs over at /r/futurology.
