“…Due to genetic mutations that cause hepcidin deficiency or interfere with its interaction with ferroportin, dietary iron absorption increases [11]. HFE gene mutations lead not only to enhanced iron uptake and its increased plasma concentrations, but also to progressive iron deposition in the cytoplasm of parenchymal cells of various organs and tissues (particularly hepatocytes, pancreatic cells, cardiomyocytes, skin, joints, and other organs), causing deleterious complications with multi-organ damage years later if left untreated [12,13]. The toxic impact of surplus iron stems from the development of oxidative stress with free oxygen radical generation (i.e., hydroxyl and peroxide radicals in the Fenton and Haber-Weiss reactions).…”

“…confirmatoria para el diagnóstico de hemocromatosis tipo 1 es el estudio del gen HFE (disponible en casi todos los laboratorios), pudiendo ser C282Y/C282Y, C282Y/H63D o C282Y/ S65C (20,21) . La evaluación genética de la hemocromatosis no HFE (genes HJV, HAMP, TFR2 y SCL40A1) solo se realiza en unos pocos centros en el mundo (1) .…”

“…Se deberá limitar también el consumo de mariscos crudos para evitar el riesgo de infección por Vibrio vulnificus, favorecida por la presencia de elevado contenido de hierro tisular. Tampoco debería consumirse vitamina C en demasía dado que favorece la absorción de hierro (20) .…”

“…Due to genetic mutations that cause hepcidin deficiency or disrupt its binding to ferroportin, dietary iron absorption increases [10]. HFE gene mutations lead not only to enhanced iron uptake and its increased plasma concentrations, but also to progressive iron deposition in the cytoplasm of parenchymal cells of various organs and tissues (particularly hepatocytes, pancreatic cells, cardiomyocytes, skin, joints, and other organs) causing deleterious complications with multi-organ damage years later if untreated [11,12]. The toxic impact of surplus iron stems from the development of oxidative stress and the production of free oxygen radicals (i.e., hydroxyl and peroxide radicals in the Fenton and Haber-Weiss reactions) which 2 destroy intracellular organelle membranes, trigger DNA strand breaks, and lead to cell injury.…”
