摘要

这项工作的目的是研究贝都因人部落对苯硫酰胺（PTC）的味觉敏感性，并将贝都因人与阿拉伯和犹太人口进行比较。通过系列稀释的经典方法获得的317名健康男性贝都因人的数据进行了检查，这些人年龄在16-70岁之间，属于不同的部落。我们发现贝都因社区对PTC的化学敏感性存在显著差异。在Hamada、Muzeina和“其他贝都因人”的贝都因人部落中，t等位基因的频率很高，而在Gebelia部落中，t等位基因频率相对较低。阿拉伯群体中不品尝者的频率在价值观上与Gebelia部落相似。另外三个贝都因人部落显示出非常高的非品尝者频率值。所揭示的部落间差异可以用孤立群体的遗传漂移来解释，另一方面，这可能是内交配的结果。

Taste sensitivity to phenylthiocarbamide found in South Sinai Bedouin tribes

The aim of this work was to study taste sensitivity to phenylthiocarbamide (PTC) amongst Bedouin tribes and compare the Bedouins with Arab and Jewish populations. Data obtained by the classic method of serial dilutions in 317 healthy male Bedouins, aged 16–70 belonging to different tribes, were examined. We discovered significant differences in chemosensitivity to PTC in the Bedouin communities. A high frequency of the t allele was documented in the Bedouin tribes of Hamada, Muzeina, and “other Bedouins” and a relatively low level of the t allele frequency in the Gebelia tribe. The frequencies of non-tasters amongst Arab groups were similar in values to those of the Gebelia tribe. Three other Bedouin tribes showed very high values for the non-tasters’ frequencies. The revealed intertribal differences can be explained by the genetic drift in isolated populations, on the other hand, this may be the result of endogamy.
