Your DNA Is a Machine Learning Model: It’s Already Out There

DNA testing services can no longer guarantee genetic privacy due to advanced machine learning techniques. These methods can reconstruct an individual's genetic profile using data from distant relatives, similar to nearest-neighbor classification. The Golden State Killer case demonstrated this approach's use in forensics. Polygenic risk scores for disease risk can also be predicted for untested individuals. These developments raise concerns about privacy, potential misuse, and adversarial attacks on genetic databases.
