TIKKI knowledge answer
TCF7L2 is a transcription factor strongly linked to type 2 diabetes risk via GWAS. Fatigue is not a direct symptom of TCF7L2 variants, but may arise indirectly through impaired glucose regulation or insulin resistance. Evidence for a direct role in fatigue is weak; the primary association is with diabetes predisposition. Genetic testing indicates risk only, not a diagnosis. Persistent fatigue warrants medical evaluation for other causes (sleep, diet, stress).
