RT Journal Article T1 Genetic diversity of HLA system in four populations from Baja California, Mexico: Mexicali, La Paz, Tijuana and rural Baja California A1 Escobedo-Ruíz, Araceli A1 Barquera, Rodrigo A1 González-Martín, Antonio A1 Argüelles-San Millán, Juan Manuel A1 Uribe-Duarte, María Guadalupe A1 Iraíz Hernández-Zaragoza, Diana A1 Clayton, Stephen A1 Arrieta-Bolaños, Esteban A1 Ruíz Corral, María de Jesús A1 Goné-Vázquez, Isis A1 Arellano-Prado, Francia Paulina A1 Martínez-Álvarez, Julio César A1 García-Arias, Víctor Eduardo A1 Rodríguez-López, Marla Estefanía A1 Bravo-Acevedo, Alicia A1 Sánchez-Fernández, María Guadalupe de Jesús A1 Aguilar-Campos, Jesús Abraham A1 Gómez-Navarro, Benjamín A1 Sandoval-Sandoval, Mario J. A1 Serrano-Osuna, Ricardo A1 Yunis, Edmond J. A1 Zúñiga, Joaquín A1 Bekker-Méndez, Carolina A1 Granados, Julio AB 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 (N = 100), La Paz (N = 75), Tijuana (N = 25) and rural communities (N = 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 ± 1.84% by ML; 42.03% of European haplotypes) and Native American (43.72 ± 2.36% by ML; 40.24% of Native American haplotypes), while the African genetic component was less apparent (5.83 ± 0.98% by ML; 9.36% of African haplotypes).
