Is COMT useful for stress?

The COMT gene (e.g., rs4680 Val/Val) is often discussed in relation to stress because it influences dopamine breakdown. However, the evidence is primarily mechanistic, and its practical usefulness for managing stress is limited. Lifestyle factors such as sleep, exercise, and nutrition have a far greater impact. A DNA test alone cannot predict your stress resilience or guide treatment. Clinical relevance is low, and consumers should be cautious about overinterpreting direct-to-consumer results. Evidence: mechanistic.
