I think it needs to be a crime to analyze someone's genes without their permission. I can see the potential for abuse. The article mentions that a significant other might ask for genetic testing before marriage. Why would they need to ask? They could just steal some genetic material during the night.
Also, these gene companies don't seem to be forthcoming about genetics. There is a lot that we still don't understand. Even if you inherit a gene that is linked to a disease, you may not necessarily express that gene. Genetic expression is very poorly understood right now.
