As I said, because of my Jewish background, I was aware of the unusually high rate of Tay-Sachs in the Ashkenazi population.

正如我所说的，因为我的犹太背景，我很清楚阿什肯纳兹犹太裔中泰伊-萨克斯病的风险异常高。

But the unusual prevalence of the Tay-Sachs mutation in Ashkenazi populations may be another example of heterozygote advantage.

但是泰伊-萨克斯突变在阿什肯纳兹犹太人群中的异常流行，可能是另一个杂合子优势的案例。

Taken together, these findings show a likely genetic basis for the increase in TSH in this Ashkenazi Jewish centenarian population as well as their children.

总的来说，这些发现显示在中欧犹太百岁老人以及子女中，具有基因背景相关的TSH升高现象。

The researchers compared the findings to other Ashkenazi Jews whose family members did not live as long. In the control group, they say, no one had the mutations.

研究人员把他们发现差异的基因和其他相对寿命较短的德系犹太人家庭成员的基因做对比，但是观察小组研究员却没有发现任何一个出现过变异的基因。
