例如，因为突变的基因可以提高铁的吸收效率，所以遗传性血色素沉着病突变可以保护带菌者不缺铁。

For example, the hereditary hemochromatosis mutation protects carriers from iron-deficiency because the mutated gene allows increased efficiency of iron absorption.

其它研究已经发现了一些罕见的基因突变，这些突变对病人的消化吸收和利用维生素b12的能力有很大的影响。

Other studies have found rare gene mutations with dramatic effects on people's ability to digest, absorb, and use vitamin B12.

该病是由于血色素沉着症基因(HFE)突变使得肠吸收铁增加所致。

HHC results from a mutation involving the hemochromatosis gene (HFE) that leads to increased iron absorption from the gut.
