Hemochromatosis is primarily associated with an autosomal recessive inheritance pattern. This means that an individual must inherit two copies of the mutated gene, one from each parent, in order to manifest the disease. The gene most commonly implicated in hereditary hemochromatosis is HFE, which plays a vital role in the regulation of iron absorption in the body. When a person has two mutated copies of this gene, it leads to increased intestinal absorption of iron and subsequent iron overload in various organs, which can result in serious health complications.

In contrast, other inheritance patterns listed do not apply to hemochromatosis. X-linked dominant conditions typically affect males more severely than females and require only one copy of the mutated gene. Autosomal dominant conditions require just one copy of the mutated gene to express the phenotype, while chromosomal aberration pertains to structural changes in chromosomes rather than a straightforward gene mutation. Thus, the autosomal recessive inheritance pattern accurately reflects how hemochromatosis is passed through families.
