Evidence check: MC4R in the context of Wechseljahre

MC4R (melanocortin-4 receptor) is a key regulator of energy balance and appetite. Variants such as rs17782313 have been linked to obesity and increased caloric intake in GWAS. In the context of menopause, hormonal shifts significantly influence weight gain and metabolic changes. Some studies suggest MC4R variants may modulate weight trajectories during this period, but the evidence is limited and not robust enough for clinical guidance. A MyBody-X DNA test can detect such variants, but results are non-diagnostic and should not replace medical advice. The predictive value for menopause-specific effects is weak, as lifestyle, diet, and hormone status are far more influential. Be cautious of overblown claims: MC4R is not a 'menopause gene'. Under Germany's Genetic Diagnostics Act (GenDG), direct-to-consumer tests cannot provide medical diagnoses. For evidence-based weight management during menopause, conventional biomarkers and physician oversight remain essential.
