Distribution of apolipoprotein E alleles in coras and huicholes from Nayarit and Nahuas and Mestizos from Veracruz, Mexico.

We report allele frequencies for the most common polymorphism of the APOE gene in Mexican individuals from two regions not previously described: Coras and Huicholes from Nayarit, and Nahuas and mestizos from Veracruz. We also report APOE allele frequencies for inhabitants of Mexico City. These descriptive data underscore the allelic heterogeneity for this particular locus in Mexico.
