Abstract

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 1011 Mexicans from the state of Tlaxcala residing in the city of Tlaxcala (N = 181) and rural communities (N = 830), to obtain information regarding allelic and haplotypic frequencies. We find that the ten most frequent haplotypes in Tlaxcala are all of Native American origin. Admixture estimates revealed that the main genetic components are Native American (75.13 ± 1.56% by ML; 69.24% based on of Native American haplotypes) and European (16.10 ± 4.98% by ML; 19.74% of European haplotypes), with a less prominent African genetic component (8.78 ± 4.09% by ML; 4.35% of African haplotypes).

Abstract

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 81 Mexicans from the state of Campeche living in the city of Campeche (N = 34) and rural communities (N = 47), to obtain information regarding allelic and haplotypic frequencies. We find that the most frequent haplotypes in the state of Campeche include ten Native American, three European, one African and one Asian haplotype. Admixture estimates revealed that the main genetic components in the state of Campeche are Native American (65.56 ± 0.96% by ML; 51.24% of Native American haplotypes), European (34.44 ± 10.94% by ML; 30.25% of European haplotypes), and a virtually absent African genetic component (0.00 ± 10.31% by ML; 9.26% of African haplotypes).

Abstract

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 1113 Mexicans from the state of Veracruz living in the cities of Coatzacoalcos (N = 55), Orizaba (N = 60), Córdoba (N = 56), Poza Rica (N = 45), Veracruz (N = 171), Xalapa (N = 187) and rural communities (N = 539) to obtain information regarding allelic and haplotypic frequencies. We found that the most frequent haplotypes include 12 Native American haplotypes. Admixture estimates revealed that the main genetic components are Native American (64.93 ± 1.27% by ML; 55.10% of Native American haplotypes) and European (26.56 ± 0.89% by ML; 28.38% of European haplotypes), and a relatively high African genetic component (8.52 ± 1.82% by ML; 8.78% of African haplotypes).
