Abstract
Abstract
Background
Being the native inhabitants of the Neolithic Fertile Crescent, Kurds were included in several maternal lineage studies concerning the Eurasian population. However, no study was performed on the Kurdish population of Sulaymaniyah city (latitude 33.314690 and longitude 44.376759). This study was carried out on a sample of Sorani Kurds living in Sulaymaniyah for the identification of population-related single nucleotide polymorphisms (SNPs) and modes of maternal lineage.
Results
In this study, 36 randomly selected healthy unrelated Kurdish subjects were enrolled. Whole mitochondrial DNA sequencing was performed. HaploGrep 2.0 and neutrality test (Tajima’s D) were employed for haplogroup identification and historical demography determination. When the outcomes were compared with previous studies in Kurds and the neighbouring nations, the identified haplogroups in the sample of study were members of the Western Eurasian haplogroups with a predominance of haplogroup H.
Conclusions
The whole mitochondrial DNA sequence is superior to the traditional analysis of the non-coding (control) region. Our study indicates a stronger relation of the studied group to the European lineage than to their neighbouring nations.
