Abstract:
We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 453 Mexicans from the state of Zacatecas living in Zacatecas city (N = 84), Fresnillo (N = 103) and rural communities (N = 266) to obtain information regarding allelic and haplotypic frequencies and their linkage disequilibrium. We find that the most frequent haplotypes for the state of Zacatecas include seven Native American most probable ancestry (A*02 ∼ B*39 ∼ DRB1*04 ∼ DQB1*03:02; A*02 ∼ B*35 ∼ DRB1*08 ∼ DQB1*04; A*24 ∼ B*39 ∼ DRB1*14 ∼ DQB1*03:01; A*02 ∼ B*35 ∼ DRB1*04 ∼ DQB1*03:02; A*24 ∼ B*35 ∼ DRB1*04 ∼ DQB1*03:02; A*68 ∼ B*35 ∼ DRB1*04 ∼ DQB1*03:02 and A*24 ∼ B*35 ∼ DRB1*08 ∼ DQB1*04) and two European MPA haplotypes (HLA ∼ A*01 ∼ B*08 ∼ DRB1*03:01 ∼ DQB1*02 and A*29 ∼ B*44 ∼ DRB1*07 ∼ DQB1*02). Admixture estimates revealed that the main genetic components in the state of Zacatecas are European (47.61 ± 1.85%) and Native American (44.74 ± 1.12%), while the African genetic component was less apparent (7.65 ± 1.12%). Our findings provide a starting point for the study of population immunogenetics of urban and rural populations from the state of Zacatecas and add to the growing knowledge on the population genetics of Northern Mexico.
