...and the limited gene pool created by this isolated community now provides a unique opportunity

这个与世隔绝的社会创造的有限的基因库现在提供了一个独特的机会,

to discover specific genes that are associated with long life.

去发现与长寿相关的特别的基因。

After years of searching, Deiana has detected a number of unusual genetic characteristics

通过几年的探索,Deiana已经发现了一些不寻常的遗传特征,

that seem to link the centenarians of Ovodda.

but in Ovodda, it may well have had a positive effect.

We have been discovering things of great interest,

such as how certain genetic characteristics could have determined diseases like malaria

which may be associated with the lack of a very significant enzyme in our centenarians.

The role G6PD may play in living longer remains a mystery,
