Gorgan (Iran) population HLA genetics and anthropology

Gorgan (Iran) have been studied for HLA-A, -B, -C, -DRB1 and -DQB1 genes for the first time. They are Turkmen and originated in East Asia around Altai Mts; they originally spoke a Turk language classified within the Turkish-Oguz group. Peripheral blood samples were collected from Gorgan City (Iran) and HLA typed by standard methodology. HLA allele frequencies were compared with 7984 chromosomes of other World populations and it was shown existence of admixture of Siberian and Mediterranean HLA characters in this population, probably due to longlasting contact with Persians. Three new HLA extended haplotypes were found: A*01:01-B*35:01-DRB1*03:01-DQB1*02:01, A*30:01-B*13:01-DRB1*15:01-DQB1*02:01 and A*31:01-B*35:01-DRB1*15:01-DQB1*03:01. Gorgan (Iran) were most close to Chuvashians (Noth Caspian Sea, Russia) and Siberians, like Tuvinians, Mansi and Buryats in Neighbour Joining and Vista analyses. It is established a relationship of this population with Kurgan (Gorgan, Iran) archaeological mounds culture. However, their kinship with Scythians (2nd century BC) and Sarmatians (4th century AD) is obscure although both of them spoke a Persian language. © 2019 American Society for Histocompatibility and Immunogenetic

Description of new american carduelis/spinus bird species in la paz (Bolivia): C./s. lapazensis

10 Pág.Introduction: South American siskins (Genus Carduelis/Spinus) are the outcome of regional evolutionary radiation from an extant (or other extinct) species: C. notata, a North America siskin, which thrives in Mexico subtropical areas and is parental of one of the three described North American siskin radiations. Methods: Speciation and/or subspeciation of this South American siskin radiation have probably occurred during Pleistocene Epoch. In the present paper, a new species/subspecies akin to C./S. atrata is described by genetic and phenotypic parameters: this new species/subspecies was previously considered a subspecies of C./S. xanthogastra, which thrives further North and is separated about 1,762 km, 1,094 miles, from this described subspecies, Carduelis/ Spinus xanthogastra stejnegeri. Results: Our genetic study using mt cyt b, phenotypic and behavior observations show that this putative C./S. xanthogastra subspecies is either a different species or a C./S.atrata subspecies; we have proposed a provisional name for this finch, C./S. lapazensis, instead of C./S. x. stejnegeri. Conclusion: Species definition is movable and controversial, and it is uncertain in South American siskins, which all show a close genetic and phenotypical relationship, which may be still immersed in speciation processes since Pleistocene Epoch.This work was supported by grants from the Spanish Ministry of Science and Universities (PI14/01067, PI18/00720 and PI18/00626) and European FEDER funds.Peer reviewe

Study of Colombia North Wiwa El Encanto Amerindians HLA- genes: Pacific Islanders relatedness

We have studied Wiwa/Sanja Amerindians HLA-A, -B, -C, -DRB1 and DQB1 allele frequencies and extended haplotypes in 52 unrelated individuals from “El Encanto” town at Guanachaca riverside. High frequency alleles were in general present in other Amerindian populations. Also, three extended haplotypes and eight ones were respectively both “new found” and already described in Amerindians from North, Central and South America, including Lakota-Sioux, Mayas, Teeneks, Quechua and Aymaras. Analyses of HLA-A*24:02 and -C*01:02 Wiwa high frequency alleles suggested a specific relatedness with another Amerindian and Pacific Islander ethnic groups (these two particular alleles bearing in high frequencies); they include New Zealand Maoris, Taiwanese, Japanese, Papua New Guinea, and Samoans among others. This may indicate that selective forces are maintaining these two alleles high frequency within this wide American/Pacific area. © 201
