Northern Navarre is a neighboring area with Guipúzcoa, a province located in the core of the Basque territory having the highest proportion of Basque-speakers. In Navarrese population, the most frequent alleles were DQA1*01 (0.375) and DQA1*02 (0.259). Frequency clines for both DQA1*0103 allele and DQA1*04* allele cluster (including DQA1*0401, DQA1*0501 and DQA1*0601) among the European and Mediterranean populations considered are reported for the first time. Furthermore, a spatial structuring previously described for DQA1*02 allele is corroborated. The information provided by the highly polymorphic HLA-DQA1 locus was stressed by using genetic distances and non-metrical multidimensional scaling (MDS). The analysis of genetic relationships among populations showed a high genetic affinity between the Basque subpopulations of Northern Navarre and Guipúzcoa, which in turn tended to plot separately from the remaining European and Mediterranean populations. In the same way, the Basques showed no clear relationship to North African populations, as postulated in several previous HLA studies. The observed genetic heterogeneity seems to be conditioned by the high frequencies of the DQA1*02 allele in Basques from Guipúzcoa and North Navarre. These two subpopulations seem to show low levels of admixture with other non-Basque neighboring populations, probably because of their deeply rooted ethnicity and the existence of a linguistic barrier to random mating."xsd:string |
