Project description:Mammals have evolved an XY sex chromosome system, resulting in dosage imbalance not only between sexes, but also between X-chromosome and autosome. mRNA profiles of 9 pairs of human endometrial carcinoma and adjacent tissues were generated by Illumina 100-nucleotide paired-end sequencing
Project description:Whole genome genotyping (WGG) arrays are the powerful tools for GWAS in farm animal. Here we take advantage of the commercial Illumina PorcineSNP60 BeadChips, a mapping population including 101 individuals were genotyped. Association analysis and linkage analysis were followed to map the causative gene of hearing loss in Chinese Rongchang pigs.
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:Low-pass sequencing (sequencing a genome to an average depth less than 1× coverage) combined with genotype imputation has been proposed as an alternative to genotyping arrays for trait mapping and calculation of polygenic scores. To empirically assess the relative performance of these technologies for different applications, we performed low-pass sequencing (targeting coverage levels of 0.5× and 1×) and array genotyping (using the Illumina Global Screening Array (GSA)) on 120 DNA samples derived from African and European-ancestry individuals that are part of the 1000 Genomes Project. We then imputed both the sequencing data and the genotyping array data to the 1000 Genomes Phase 3 haplotype reference panel using a leave- one-out design. We evaluated overall imputation accuracy from these different assays as well as overall power for GWAS from imputed data, and computed polygenic risk scores for coronary artery disease and breast cancer using previously derived weights. We conclude that low-pass sequencing plus imputation, in addition to providing a substantial increase in statistical power for genome wide association studies, provides increased accuracy for polygenic risk prediction at effective coverages of ∼ 0.5× and higher compared to the Illumina GSA.
Project description:Genome-wide DNA Methylation Data from Illumina HumanMethylationEPIC arrays for whole blood samples from 570 healthy individuals. Raw IDAT files are available for a subset of 403 samples on EGA. Raw data (IDAT files) and associated phenotype information are available for all individuals included in this study (n=570) directly from CIBMTR. Data are available under controlled access release upon reasonable request and execution of a data use agreement. Requests should be submitted to CIBMTR at info-request@mcw.edu and include the study reference IB17-04.

Project description:Diverse dataset of 1247 dogs from many breeds and wolves used to investigate the origins of dog domestication DNA for 1228 dogs from 35 breeds and 19 wolves was extracted from whole blood samples and genotyped on the Affymetrix Canine v2 Arrays. Genotypes were called using Affymetrix's snp5-probeset-genotype software and the BRLMM-P calling algorithm. The included breed designations are owner reported.
Project description:Whole genome genotyping (WGG) arrays are the powerful tools for GWAS in farm animal. Here we take advantage of the commercial Illumina PorcineSNP60 BeadChips, a mapping population including 101 individuals were genotyped. Association analysis and linkage analysis were followed to map the causative gene of hearing loss in Chinese Rongchang pigs. To Mapping the causative gene of hearing loss in Chinese Rongchang pigs, we genotyped 60000 markers in the genome of a mapping population including 101 individuals. Illumina 60K BeadChips were used. Sample types were normal blood samples.
