Open Archive of Plant Images and Traits
The world of agriculture is constantly evolving, with new technologies continuously shaping the way we understand and interact with plants. One such advancement is the development of high-throughput plant phenotypic collection technology, which has revolutionized the field of plant phenomics. Through this technology, scientists are able to gather vast amounts…
Genes that shape facial features
After turning up hundreds of genes with hard-to-predict effects, some scientists are now probing the grander developmental processes that shape face geometry When Eric Mueller, who was adopted, first saw a photograph of his birth mother, he was overcome by how alike their faces were. It was, he wrote, “the…

HLA allele-calling using multi-ancestry whole-exome sequencing from the UK Biobank identifies 129 novel associations in 11 autoimmune diseases
HLA allele calling from WES HLA-HD was used to call HLA alleles for 454,824 participants at 3-field resolution (representing the allele’s serological specificity, HLA protein, and synonymous variants). We used the UKB whole-genome genotyping (unavailable in 1283 participants) projected on the 1000 Genome reference to estimate genetic ancestry. We found…
eQTL colocalization analysis highlights novel susceptibility genes in Autism Spectrum Disorders (ASD)
Autism Spectrum Disorders (ASD) are a group of neurodevelopmental disorders (NDDs) characterized by difficulties in social interaction and communication, repetitive behavior, and restricted interests. ASD has proven to have a strong genetic component. However, defining causal genes is still one of the main challenges in GWAS, since the vast majority…
Recent GWAS studies have made extensive use of large eQTL data sets to functionally annotate index SNPs. With a large number of association signals located outside coding regions there has been an intense search among sequence variants affecting gene expression at the transcriptional level. However, little progress has been made in mapping regulatory variants that affect protein levels at the translational or post-translational level. It is now possible to undertake a protein QTL scan for focused sets of e.g. oxidized proteins by mass spectrometry. We have established a collaboration with a longitudinal, family-based study in France, the Stanislas cohort, which comprises circa 1000 nuclear families (4,295 individuals) and has follow up data for 10 years (three visits). We have undertaken a pilot study in a focus set of 257 subjects from 79 families with the aim to integrate GWAS, transcriptomic and DNA methylation data with proteomic data on a set of 100 proteins measured in PBMCs. We have already generated GWAS data using Illumina’s core-exome chip as well as DNA methylation profiles with the 450K array. We propose to use RNA seq to generate transcriptomic data of the corresponding PBMCs. This data is part of a pre-publication release. For information on the proper use of pre-publication data shared by the Wellcome Trust Sanger Institute (including details of any publication moratoria), please see http://www.sanger.ac.uk/datasharing/
