RESUMO
We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 161 Mexicans from the state of Nayarit living in Tepic (Nâ¯=â¯97) and rural communities (Nâ¯=â¯64), to obtain information regarding allelic and haplotypic frequencies. We find that the ten most frequent haplotypes found in the state of Nayarit include eight Native American and two European haplotypes. Admixture estimates revealed that the main genetic components in the state of Nayarit are Native American (50.79⯱â¯5.03% by ML; 42.24% of Native American haplotypes) and European (37.04⯱â¯6.21% by ML; 35.72% of European haplotypes), while African genetic component is less apparent but relatively high (12.17⯱â¯2.50% by ML; 13.36% of African haplotypes).

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 250 Mexicans from the states of Baja California Norte and Baja California Sur living in Mexicali (Nâ¯=â¯100), La Paz (Nâ¯=â¯75), Tijuana (Nâ¯=â¯25) and rural communities (Nâ¯=â¯50) to obtain information regarding allelic and haplotypic frequencies. The most frequent haplotypes for the Baja California region include nine Native American and five European haplotypes. Admixture estimates revealed that the main genetic components are European (50.45⯱â¯1.84% by ML; 42.03% of European haplotypes) and Native American (43.72⯱â¯2.36% by ML; 40.24% of Native American haplotypes), while the African genetic component was less apparent (5.83⯱â¯0.98% by ML; 9.36% of African haplotypes).

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 286 Mexicans from the state of Sinaloa living in Culiacán (Nâ¯=â¯103) and rural communities (Nâ¯=â¯183) to obtain information regarding allelic and haplotypic frequencies. We find that the most frequent haplotypes for the state of Sinaloa include ten Native American most probable ancestry and five European most probable ancestry haplotypes. The admixture estimates revealed that the main genetic components in the state of Sinaloa are European (62.39⯱â¯3.47%) and Native American (37.61⯱â¯2.85%), while the African genetic component was estimated as virtually absent (0.00⯱â¯1.86%).

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 262 Mexicans from the state of Guanajuato living in the cities of Guanajuato (Nâ¯=â¯78), León (Nâ¯=â¯22) and rural communities (Nâ¯=â¯162), to obtain information regarding allelic and haplotypic frequencies. We find that the most frequent haplotypes found in the state of Guanajuato include 12 Native American and three European haplotypes. Admixture estimates revealed that the main genetic components in the state of Guanajuato are Native American (50.64⯱â¯2.11% by ML, 43.35% of Native American haplotypes) and European (44.14⯱â¯1.14% by ML; 39.35% of European haplotypes), while African genetic component is less apparent (5.22⯱â¯2.08% by ML; 8.36% of African haplotypes).

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 104 Mexicans from the state of Colima living in the city of Colima (Nâ¯=â¯61) and rural communities (Nâ¯=â¯43), to obtain information regarding allelic and haplotypic frequencies. We find that the most frequent haplotypes in the state of Colima include eight Native American, two European and one African haplotype. Admixture estimates revealed that the main genetic components in the state are Native American (52.74⯱â¯3.88% by ML; 48.10% of Native American haplotypes) and European (37.52⯱â¯8.94% by ML; 26.66% of European haplotypes), and a relatively high African genetic component (9.74⯱â¯8.40% by ML; 11.91% of African haplotypes).

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).

We studied HLA class I (HLA-A, -B) and class II (HLA-DRB1, -DQB1) alleles by PCR-SSP based typing in 498 Mexicans from the state of Michoacán living in the city of Morelia (Nâ¯=â¯150) and rural communities (Nâ¯=â¯348), to obtain information regarding allelic and haplotypic frequencies. We find that the ten most frequent haplotypes found in the state of Michoacán include 12 Native American and two European haplotypes. Admixture estimates revealed that the main genetic components in the state of Michoacán are Native American (48.79⯱â¯1.44%) and European (43.10⯱â¯0.86%), while African genetic component is less apparent (8.11⯱â¯0.85%). Our findings add to the growing knowledge on the population genetics of Western Mexico and provide new HLA data on populations from Michoacán.
