Project description:Hispanic/Latino populations possess a complex genetic structure that reflects recent admixture among and potentially ancient substructure within Native American, European, and West African source populations. Here, we quantify genome-wide patterns of SNP and haplotype variation among 100 individuals with ancestry from Ecuador, Colombia, Puerto Rico, and the Dominican Republic genotyped using Illumina technology.

Project description:In this study, we sequence 150 genomes to high coverage from Native American and mestizo populations in Peru. The majority of our samples possess greater than 90% Native American ancestry, which makes this the most extensive Native American sequencing project to date.

Project description:<p>Stanford contributed samples to the PAGE study that can act as a population reference dataset across the globe. Therefore this dataset includes reference individuals, without phenotypes, chosen to help infer ancestry that will help us understand the diverse samples available in PAGE. The complete dataset comprises individuals of European, African, Asian, Oceanian, and Native American descent, from a total of over 50 populations. A subset of these individuals from Puno, Peru and Easter Island (Rapa Nui), Chile, are included in the PAGE samples that were whole genome sequenced in 2015. Additional details are available in the Study Acknowledgments.</p> <p>The Global Reference Panel comprises 6 sample sets: <ul><li>A population sample of Andean individuals primarily of Quechuan/Aymaran ancestry from Puno, Peru</li> <li>A population sample of Easter Island (Rapa Nui), Chile</li> <li>Individuals of indigenous origin from Oaxaca, Mexico</li> <li>Individuals of indigenous origin from Honduras</li> <li>Individuals of indigenous origin from Colombia</li> <li>Individuals of indigenous origin from the Nama and Khomani KhoeSan populations of the Northern Cape, South Africa</li></ul> </p> <p>In addition, we genotyped publicly available samples that will be hosted on the Bustamante lab website (<a href="https://bustamantelab.stanford.edu/">https://bustamantelab.stanford.edu/</a>).

Project description:The genetic structure of some native Bolivians has been substantially influenced by admixture from Europeans, which we estimate to have occurred approximately 360 – 384 years ago. Consistent with historical accounts of male admixture, Y-chromosome haplogroups typical of Europeans were found in 39% of our Bolivian samples. No evidence of African admixture was found in native Bolivians. The Mesoamerican Totonacs have little evidence of European or African admixture. Our analysis indicates that some admixed Bolivians have Native American mtDNA and Y-chromosomes but harbor up to 30% European autosomal ancestry, demonstrating the need for autosomal markers to assess ancestry in admixed populations. From a dense genome-wide panel of 815,377 markers, we developed a set of 324 AIMs, specific for Native American ancestry. As few a 40-50 of these markers successfully predict New World ancestry in the ascertainment panel of Bolivians and Totonacs. The markers easily distinguish New World from Old World ancestry, even for populations more closely related to the Americas such as central and eastern Asians, and were effective for New World vs. Old World comparisons in five other geographically and culturally distinct populations of the Americas. SNPs demonstrating very high divergence between the two Native American populations and major Old World populations are found on haplotypes that are shared and occur at similar frequencies in other indigenous low-admixture American populations examined here (i.e. Pima, Maya, Colombian, Karitiana, and Surui). After excluding the possibility of recent relatedness, our results indicate that native Bolivians and Totonacs share ancestry with other American populations through a substantial contribution from a common founding population, population bottlenecks, and possible natural selection on functional variation.

Project description:Genome wide DNA methylation profiles of various human brain regions (cerebellum, occipital lobe, etc). The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 480,000 CpGs. The dataset includes 130 samples. Multiple brain regions were assessed per subject. The goal was to evaluate the effect of HIV infection on DNA methylation levels. Genome wide DNA methylation profiles of various brain regions from HIV positive and negative subjects. The Illumina Infinium 450k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 480,000 CpGs. Dataset included 130 samples: 99 samples from HIV+ subjects and 31 samples from HIV- subjects.

Project description:Hispanic/Latino populations possess a complex genetic structure that reflects recent admixture among and potentially ancient substructure within Native American, European, and West African source populations. Here, we quantify genome-wide patterns of SNP and haplotype variation among 100 individuals with ancestry from Ecuador, Colombia, Puerto Rico, and the Dominican Republic genotyped using Illumina technology. To investigate variations of continental ancestry between different Hispanic/Latino groups (using self-reported country-specific identification of individual, both parents, and all four grandparents) and within them from healthy controls represented in the New York Health Project Biorepository. Genotyped on the Illumina 610-Quad, which is identical to HumanHap550-v3 SNPs plus an additional ~60,000 SNPs for CNV, no CNV data is provided or was analyzed.
