An investigation using various methods reports an association between adeno-associated virus 2 and paediatric hepatitis of unknown aetiology.

Available wheat genomes are annotated by projecting Chinese Spring gene models across the new assemblies. Here, the authors generate de novo gene annotations for the 9 wheat genomes, identify core and dispensable transcriptome, and reveal conservation and divergence of gene expression balance across homoeologous subgenomes.

It’s not always clear whether blood biomarkers are differentially expressed in the time course of viral infections. In this SARS-CoV-2 human challenge study, the authors identify distinct single-gene blood transcriptional biomarkers for early stages of infection or for symptomatic infection.

Digenic inheritance of deleterious variants in serine/arginine protein kinase 3 (SRPK3) and titin (TTN) leads to a progressive early onset skeletal muscle myopathy. Zebrafish double mutants exhibit a similar myopathy phenotype accompanied by myofibrillar disorganization.

Observations of six transiting planets around the bright nearby star HD 110067 show that they follow a chain of resonant orbits, with three of the planets inferring the presence of large hydrogen-dominated atmospheres.

Machine-learning algorithms trained on 25,000 geolocated soil samples are used to create high-resolution global maps of mycorrhizal fungi, revealing that less than 10% of their biodiversity hotspots are in protected areas.

Using engineered cardiac tissues, Fleischer, Nash et al. found that patients with lupus-mediated cardiac damage have unique autoantibodies that can independently alter tissue function. They also identified autoantibodies associated with heart injury.

Comparison of multiple genome assemblies from wheat reveals extensive diversity that results from the complex breeding history of wheat and provides a basis for further potential improvements to this important food crop.

Glaucoma is the most common cause of irreversible blindness worldwide. Here, the authors carry out a large meta-analysis of genetic data from individuals of European and Asian ancestry and identify 10 new loci associated with vertical cup-disc ratio, a key factor in the clinical assessment of patients with glaucoma.

Single-cell transcriptomics studies on human and mouse non-small cell lung cancer and conditional knockout mouse models show that IL-4 from bone marrow basophils drives the development of granulocyte-monocyte progenitors to myeloid cells that suppress antitumour immunity.

This report by the Consortium for Refractive Error and Myopia uses gene-environment-wide interaction study (GEWIS) to identify genetic loci that affect environmental influence in myopia development, and identifies ethnic specific genetic loci that attribute to eye refractive errors.

Barrett’s esophagus is a pre-malignant condition that can progress to esophageal cancer. Here, the authors carry out whole genome sequencing of samples from patients who did or did not progress to cancer and find that mutations in many genes occur regardless of progression status, but also find features associated with progressive disease.

Drake and colleagues demonstrate that castration in prostate cancer models promotes IL-8 secretion and immunosuppressive myeloid-derived suppressor cell migration, and that inhibiting this axis in combination with checkpoint blockade can mitigate tumor progression.

Individual SNPs have small effects on anthropometric traits, yet the impact of CNVs has remained largely unknown. Here, Kutalik and co-workers perform a large-scale genome-wide meta-analysis of structural variation and find rare CNVs associated with height, weight and BMI with large effect sizes.

Past genome-wide associate studies have identified hundreds of genetic loci that influence body size and shape when examined one trait at a time. Here, Jeff and colleagues develop an aggregate score of various body traits, and use meta-analysis to find new loci linked to body shape.

The genome sequence and genetic diversity of European ash (Fraxinus excelsior) trees reveals the species’ varying susceptibility to ash dieback.

A genome-wide association study in ~3 million individuals identifies 3,952 independent variants associated with educational attainment. A polygenic index explains 12–16% of variance for this trait and contributes to risk prediction for ten diseases.

Quantum electrodynamics predicts a rare process in which light is scattered by light. The ATLAS Collaboration reports signs of this elusive effect in the collisions of ultra-relativistic lead ions.

A genetic study identifies hundreds of loci associated with risk tolerance and risky behaviors, finds evidence of substantial shared genetic influences across these phenotypes, and implicates genes involved in neurotransmission.

Loss or over-expression of Grainyhead-like transcription factors (Grhl) prevents closure of the neural tube but the mechanism underlying this is unclear. Here, the authors show that Grhl2 regulates murine posterior-neuropore closure via changes in the identity and biomechanics of the non-neural, surface ectoderm cells.

Gene discovery and polygenic predictions from a genome-wide association study of educational attainment in 1.1 million individuals.

Progression from ductal carcinoma in situ (DCIS) to invasive ductal carcinoma (IDC) remains poorly understood. Here, the authors analyse over 2700 micro-dissected samples using transcriptomics to identify genes that characterise different stages of DCIS to IDC progression, and identify IDC-associated markers within early-stage lesions.

Tin Aung, Christopher Hammond and colleagues report the results of a large genome-wide association study of intraocular pressure. They identify four new loci associated with this trait and show that three of these loci are associated with risk of primary open-angle glaucoma.

Eric Schadt and colleagues present a predictive causal model of the immune component of inflammatory bowel disease through integration of genetic, regulatory and transcriptional data. They prioritize and validate 12 of the top key drivers experimentally in mouse colitis models and human macrophages.

A genome-wide association study in 293,723 individuals identifies 74 genetic variants associated with educational attainment, which, although only explaining a small proportion of the variation in educational attainment, highlights candidate genes and pathways for further study.

Here, using RNA sequencing and data from several cohorts, the authors find an association of the presence of inherited, chromosomally integrated human herpesvirus 6 in the placenta with a clinical diagnosis of pre-eclampsia in the mother.

The Sequencing Quality Control (SEQC) consortium shows that junction discovery and differential gene expression profiling with RNA-seq can be robust but transcript-level and absolute measurements remain challenging.

Mark Walker and colleagues report the whole-genome sequencing of 132 group A Streptococcus (GAS) isolates of a sequence type that has been associated with scarlet fever. The isolates were obtained from 58 clinical cases of scarlet fever and 83 cases without scarlet fever during the course of a recent epidemic in Hong Kong.

William Carroll and colleagues report the identification of mutations in NT5C2, encoding cytosolic 5′-nucleotidase II, which are specific for relapsed childhood acute lymphoblastic leukemia. The mutations confer increased enzymatic activity and resistance to treatment with nucleoside analog therapies in vitro.

Lavinia Paternoster and colleagues report the results of a large, multi-ancestry genome-wide association study of atopic dermatitis. They identify ten new susceptibility loci harboring candidate genes involved in innate host defense and T cell function.

The Contaminant Repository for Affinity Purification (CRAPome) is a database of annotated negative control-data that can be used for filtering out nonspecific interactions in affinity purification-mass spectrometry experiments.
