My genetic and biometric information is already in some government's databases, sometimes with more actionable information than "elevated risk of restless legs syndrome". Associating a list of 500K SNPs with my name would bother me but not that much really. It would take a lot of work to make use of it anyway and i cant think of a reason this would harm me gravely(+). Anonymized information of my DNA would bother me even less, as i m not more exceptional genetically than most people. Tbh, this is not my information, i share DNA with most of the species on earth and i didn't really create that information (unlike, say my google searches), nor did my parents. Thats why i oppose to genetic patents too, and think that DNA should be public domain.

(+): Well if someone wants to engineer a deadly virus that targets specifically me, then what can i say , that's at least a memorable way to die. But they can do that from a piece of my hair too.
