Is COMT useful for Langlebigkeit?

The utility of COMT for longevity is limited and not evidence-based. COMT (catechol-O-methyltransferase) degrades catecholamines like dopamine and norepinephrine. The common rs4680 (Val158Met) polymorphism alters enzyme activity: Val/Val = high activity, Met/Met = low activity. Some studies link the Met allele to better cognitive performance and emotional resilience, while Val allele is associated with higher pain tolerance and stress reactivity. These traits could theoretically influence healthspan, but direct evidence for lifespan extension is lacking. Most associations come from candidate gene studies with small effect sizes and poor replication. Genome-wide association studies (GWAS) for longevity rarely identify COMT as a significant locus. Consumer DNA tests often market COMT as a 'stress' or 'cognitive' gene, but actionable insights are minimal. For longevity, focusing on modifiable lifestyle factors (diet, exercise, sleep) is far more impactful. Caveat: No clinical guidelines support COMT-based interventions for longevity. Evidence: mechanistic/unclear.
