DNA analysis can be used to profile you. Health risks, ancestry, genetic conditions. This could be used to deny insurance coverages and employment opportunities due to perceived health risks.

DNA analysis is rapidly evolving to extract more information than you might initially assume. We don't know how much or how accurately DNA can be used do infer your preferences, moral instincts, aggressive tendencies, intelligence, propensity to fall victim of a scam, to become addicted, to act violently, etc.

DNA also provides insights into the genetic makeup of family members, which can face the same problems.
