Abstract

There are different public databases and open access information that can be exploited to be reused in different research projects. With this concept in mind, we carried out a study to answer the question about the prevalence of haplogroups in human populations of modern Mexico. Since the publication of genomic and mitochondrial data in Latin American populations are very scarce and with very small samples, our work proposes to consider the availability of genomic and genetic data collections that can be reused for other purposes, different from those initially proposed in the investigations where the sequences were obtained. The objective of the present study was to explore the population structure of Mexico using available information in the public database. Through the search of information in the nucleotide database of National Center of Biotechnology Information (NCBI) of complete sequences of mitochondrial genome (16 Kb) of indigenous people, Mexican Mestizo population and Mexican-Americans living in the United States, they were classified according to the polymorphisms associated with haplogroups A, B, C and D reported in the literature as the most frequent. We obtained 283 sequences, of which 255 were selected with the criteria mentioned. The haplotyping results showed 113 different clades and subclades distributed in a general way in eight haplogroups. The most frequent groups that dominate the population were the haplogroup A with 90 individuals representing 36%, followed by haplogroup B in 65 individuals representing 26% of the sample.
