但是在世界上的某些地区，比如中非，由于基因突变而导致的白化病或色素脱失的婴儿会导致人们的害怕和迷信，有时甚至会被杀死。

But in some parts of the world, such as central Africa, mutations that result in albinism (or a significant depigmentation) of a baby can provoke fear and superstition and sometimes even infanticide.

这有助于肾脏突变的远端保钠，但会以失钾为代价。

This helps the kidneys retain sodium distal to the site of the mutation but at the expense of losing potassium.

例如，结果从一个白化突变失活的基因称为酪氨酸酶，这是至关重要的黑色色素的形成。

For example, albinism results from a mutation that inactivates a gene called tyrosinase, which is vital to black pigment formation.
