True about hemochromatosis is –
**Core Concept**
Hemochromatosis is a genetic disorder characterized by excessive iron absorption, leading to iron overload and tissue damage. The underlying pathophysiology involves mutations in the HFE gene, resulting in increased intestinal absorption of dietary iron.
**Why the Correct Answer is Right**
Hemochromatosis leads to iron accumulation in various organs, including the liver, pancreas, heart, and joints. The excess iron induces oxidative stress, lipid peroxidation, and DNA damage, ultimately causing tissue dysfunction and organ failure. The HFE gene mutation affects the regulation of hepcidin, a hormone that controls iron metabolism, leading to increased iron absorption and storage.
**Why Each Wrong Option is Incorrect**
**Option A:** This option might be incorrect because it does not specify the genetic basis of hemochromatosis, which is a crucial aspect of the disorder.
**Option B:** This option might be incorrect because it does not mention the role of iron overload in the pathogenesis of hemochromatosis, which is a critical factor in the development of the disease.
**Clinical Pearl / High-Yield Fact**
Hemochromatosis is often referred to as the "iron overload" disorder, and it can lead to a range of complications, including liver cirrhosis, diabetes, and cardiomyopathy. Early diagnosis and treatment are essential to prevent organ damage and improve patient outcomes.
**Correct Answer:** C.
