Ricadute per la pratica clinica<br />
– La diagnosi di emocromatosi può essere effettuata con test genetico, tenendo presente l’eterogene<strong>it</strong>à genetica<br />
della malattia. L’approccio molecolare ha soppiantato la necess<strong>it</strong>à della biopsia epatica nella quasi total<strong>it</strong>à dei<br />
casi.<br />
– La comprensione dei meccanismi di regolazione permetterà di chiarire non solo il sovraccarico, ma anche altri<br />
disturbi del <strong>metabolismo</strong> del <strong>ferro</strong>. Lo sviluppo di un test per il dosaggio di epcidina nel siero potrà essere<br />
utile all’inquadramento clinico del sovraccarico primario e secondario, ma anche delle anemie da disordine<br />
cronico.<br />
