In the US, the bad actor here is much more likely to be insurance companies who can tune their secret algorithms to make sure no one with a gene tied to an illness which blooms later in life can get affordable heath care.
However, it's a significant risk for other types of insurance including life, disability, and long term care.
It's more than likely that they would use genetic data to deny insurance, and then settle the cases in court if they happen to get sued, which statistically is probably a rare occurrence.
The paranoia about insurance and genetics is that they simply refuse to do business with high risk customers.
