Deep dives
Understanding Hereditary Hemochromatosis
Hereditary hemochromatosis, often caused by variants in the HFE gene, leads to iron overload and affects various organ systems. It typically presents around 40 to 50 years old, with manifestations like cirrhosis and iron buildup in the liver, joints, heart, and endocrine glands. Genetic variations like H63D and C282Y play key roles in hereditary hemochromatosis, offering insights into the body's iron regulation and potential health implications.
