During 19th century, the Circassians were secluded from their lands and forced to migrate to Ottoman Empire properties. Approximately 2,346 Circassians were exiled from Istanbul to Cyprus Island. During the deportation journey, many of Circassian passed away in consequence of malaria and unknown reasons. Overall, 1,351 survivor Circassians managed to reach the island, however, many of them had faced with endemic malaria again in Cyprus. An autosomal recessive hematological disorder thalassemia was the second endemic health condition after malaria, whereas thalassemia carriers show resistance to malaria infections. A large Cypriot family with 57 members whose grandparents were supposed to be in that ship journey has been investigated in this study. Polymerase chain reaction (PCR)-amplification refractory mutation system (ARMS) analysis technique was used for genotyping the gene. The ( ) gene c.316-106C > G (IVS-II-745) (II-745) heterozygous variation have been detected. Overall, this study is a very good example for a typical natural selection. In this case, one single gene point mutation did not limit survival in the society; natively, it increased their survival changes to form new colonization and the inheritance of the mutation to the next generations.
在19世纪,切尔克斯人被赶出他们的土地,被迫迁移到奥斯曼帝国的领地。大约2346名切尔克斯人从伊斯坦布尔被流放到塞浦路斯岛。在流放途中,许多切尔克斯人因疟疾和不明原因死亡。总体而言,1351名幸存的切尔克斯人设法抵达了该岛,然而,他们中的许多人在塞浦路斯又再次遭遇了地方性疟疾。常染色体隐性血液疾病地中海贫血是仅次于疟疾的第二种地方性健康问题,而地中海贫血携带者对疟疾感染具有抵抗力。在本研究中,对一个有57名成员的塞浦路斯大家族进行了调查,其祖父母据说在那次乘船旅程中。采用聚合酶链反应(PCR)-扩增阻滞突变系统(ARMS)分析技术对该基因进行基因分型。已检测到( )基因c.316-106C>G(IVS-II-745)(II-745)杂合变异。总体而言,本研究是典型自然选择的一个很好例子。在这种情况下,一个单一的基因点突变并没有限制该群体的生存;相反,它增加了他们形成新殖民地的生存几率以及该突变向下一代的遗传。
