Genetic diversity of HLA system in two populations from San Luis Potosí, Mexico: San Luis Potosí City and rural San Luis Potosí.

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 117 Mexicans from the state of San Luis Potosí living in the city of San Luis Potosí (N = 30) and rural communities (N = 87), to obtain information regarding allelic and haplotypic frequencies. We find that the most frequent haplotypes in the state include 13 Native American, six European, two African and two Asian haplotypes. Admixture estimates revealed that the main genetic components are Native American (52.72 ±â€¯0.66% by ML; 48.29% of Native American haplotypes) and European (34.62 ±â€¯4.28% by ML; 32.48% of European haplotypes), and a relatively high African genetic component (12.66 ±â€¯4.61% by ML; 10.26% of African haplotypes).

Genetic diversity of HLA system in three populations from Coahuila, Mexico: Torreón, Saltillo and rural Coahuila.

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 684 Mexicans from the state of Coahuila living in Saltillo (N = 72), Torreón (N = 396) and rural communities (N = 216), to obtain information regarding allelic and haplotypic frequencies. We find that the ten most frequent haplotypes found in the state of Coahuila include eight Native American and two European haplotypes. Admixture estimates revealed that the main genetic components in the state of Coahuila are European (49.72 ±â€¯4.18% by ML; 37.49% of European haplotypes) and Native American (45.01 ±â€¯2.69% by ML; 42.98% of Native American haplotypes), while African genetic component is less apparent (5.27 ±â€¯1.88% by ML; 9.92% of African haplotypes).

Genetic diversity of HLA system in two populations from Tamaulipas, Mexico: Ciudad Victoria and rural Tamaulipas.

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 148 Mexicans from the state of Tamaulipas living in Ciudad Victoria (N = 23) and rural communities (N = 125), to obtain information regarding allelic and haplotypic frequencies. We found that the most frequent haplotypes in the state of Tamaulipas include ten Native American, three European and one African haplotypes. Admixture estimates revealed that the main genetic components in the state of Tamaulipas are Native American (54.69 ±â€¯0.93% by ML; 47.65% of Native American haplotypes) and European (34.66 ±â€¯5.62% by ML; 33.56% of European haplotypes), and a relatively high African genetic component (10.65 ±â€¯5.05% by ML; 12.42% of African haplotypes).

Genetic diversity of HLA system in two populations from Nuevo León, Mexico: Monterrey and rural Nuevo León.

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 665 Mexicans from the state of Nuevo León living in the city of Monterrey (N = 226) and rural communities (N = 439), to obtain information regarding allelic and haplotypic frequencies. We find that the most frequent haplotypes in the state of Nuevo León include 12 Native American and three European haplotypes. Admixture estimates revealed that the main genetic components in the state of Nuevo León are Native American (54.53 ±â€¯0.87% by ML; 48.88% of Native American haplotypes) and European (38.67 ±â€¯4.06% by ML; 32.59% of European haplotypes), and a less prominent African genetic component (6.80 ±â€¯4.30% by ML; 8.26% of African haplotypes).

Genetic diversity of HLA system in two populations from Durango, Mexico: Durango city and rural Durango.

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 479 Mexicans from the state of Durango living in Durango city (N = 153) and rural communities (N = 326), to obtain information regarding allelic and haplotypic frequencies. We find that the ten most frequent haplotypes found in the state of Durango include eight Native American and two European haplotypes. Admixture estimates revealed that the main genetic components in Durango are European (54.34 ±â€¯1.68%) and Native American (45.66 ±â€¯2.24%), while African genetic component was virtually absent (0.00 ±â€¯2.03%). However, African haplotypes could be estimated at a proportion of 9.13%.

Genetic diversity of HLA system in three populations from Chihuahua, Mexico: Chihuahua City, Ciudad Juárez and rural Chihuahua.

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 461 Mexicans from the state of Chihuahua living in Chihuahua city (N = 119), Ciudad Juárez (N = 106) and rural communities (N = 236), to obtain information regarding allelic and haplotypic frequencies and their linkage disequilibrium. We find that the most frequent haplotypes found in the state of Chihuahua include seven Native American and three European haplotypes. Admixture estimates revealed that the main genetic components in Chihuahua are European (52.12 ±â€¯0.88% by ML; 41.53% of European haplotypes) and Native American (39.51 ±â€¯2.17% by ML; 37.45% of Native American haplotypes), while African genetic component was less apparent (8.36 ±â€¯1.47% by ML; 11.70% of African haplotypes).

Genetic diversity of HLA system in a population sample from Aguascalientes, Mexico.

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 95 Mexicans from the state of Aguascalientes to obtain information regarding allelic and haplotypic frequencies and their linkage disequilibrium. We find that the most frequent haplotypes in the state of Aguascalientes include four Native American, three European and one Asian haplotypes. Admixture estimates revealed that the main genetic components in the state of Aguascalientes are Native American (54.53 ±â€¯3.22% by ML; 44.21% of Native American haplotypes) and European (44.34 ±â€¯0.45% by ML; 40.53% of European haplotypes), and a relatively low African genetic component (1.13 ±â€¯2.33% by ML; 5.26% of African haplotypes).
