Y‐chromosome diversity in Native Mexicans reveals continental transition of genetic structure in the Americas
The genetic characterization of Native Mexicans is important to understand multiethnic based features influencing the medical genetics of present Mexican populations, as well as to the reconstruct the peopling of the Americas. We describe the Y‐chromosome genetic diversity of 197 Native Mexicans from 11 populations and 1,044 individuals from 44 Native American populations after combining with publicly available data. We found extensive heterogene…
Genetic structure of Mexican Mestizo women with breast cancer based on three STR loci
The aim of this population genetics study was to compare the genetic structure of Mexican women with breast cancer (BrCa) with previously reported data of four random populations (Nuevo León, Hispanics, Chihuahua, and Central Region of Mexico). A sample of 115 unrelated women with BrCa and whose four grandparents were born in five zones of Mexico were interviewed at a reference hospital in Northeastern Mexico. Noncodifying STRs D7S820, D13S317, a…
Genetic admixture of eight Mexican indigenous populations
This study explores the genetic admixture of eight Mexican indigenous populations (Otomi‐Ixmiquilpan, Otomi‐Actopan, Tzeltales, Nahua‐Milpa‐Alta, Nahua‐Xochimilco, Nahua‐Zitlala, Nahua‐Ixhuatlancillo, and Nahua‐Coyolillo) on the basis of five PCR‐based polymorphic DNA loci (LDLR, GYPA, HBGG, D7S8, GC), HLA_DQA1, and the blood groups ABO and Rh (CcDEe). Among the indigenous populations, the highest gene frequencies for O and D were 0.9703 and 1.00…
Characterization of mtDNA Haplogroups in 14 Mexican Indigenous Populations
In this descriptive study we investigated the genetic structure of 513 Mexican indigenous subjects grouped in 14 populations (Mixteca- Alta, Mixteca-Baja, Otomi, Purépecha, Tzeltal, Tarahumara, Huichol, Nahua- Atocpan, Nahua-Xochimilco, Nahua-Zitlala, Nahua-Chilacachapa, Nahua- Ixhuatlancillo, Nahua-Necoxtla, and Nahua-Coyolillo) based on mtDNA haplogroups. These communities are geographically and culturally isolated; parents and grandparents wer…
Genetic structure of seven Mexican indigenous populations based on five polymarker loci
This descriptive study investigates the genetic structure of seven Mexican indigenous populations (Mixteca Alta, Mixteca Baja, Otomies, Purepecha, Nahuas‐Guerrero, Nahuas‐Xochimilco, and Tzeltales) on the basis of five PCR‐based polymorphic DNA loci: LDLR, GYPA, HBGG, D7S8, and GC. Genetic distance and diversity analyses indicate that these Mexican indigenous are similar and that more than 96% of the total gene diversity (H T ) can be attributed …
