When is Stress Genetik actually useful?

The usefulness of 'Stress Genetics' tests is currently very limited from a scientific perspective. These tests typically analyze single gene variants (e.g., in COMT, BDNF, or FKBP5) linked to stress processing. However, the effect sizes are small, highly context-dependent, and overshadowed by lifestyle, environment, and epigenetics. No genetic test can reliably predict how an individual will respond to stress or their risk for stress-related disorders. Most offerings are based on association studies with low clinical validity. A positive result may cause unnecessary anxiety, while a negative one may give false reassurance. Genetic analysis is only useful within a comprehensive medical workup, e.g., when a rare monogenic disorder of the stress axis is suspected. For the general population, stress management through sleep, exercise, nutrition, and mindfulness remains far more impactful. The evidence for 'Stress Genetics' tests is therefore best categorized as marketing or unclear.
