Background & Aims: A quarter of the world population is estimated to have metabolic dysfunction-associated steatotic liver disease. Here, we aim to understand the impact of liver trait-associated genetic variants on fat content and tissue volume across organs and body compartments and on a large set of biomarkers.
Methods: Genome-wide association analyses were performed on liver fat and liver volume estimated with magnetic resonance imaging in up to 27,243 unrelated European participants from the UK Biobank.

Delayed leaf senescence (staygreen) is an important agronomic trait associated with enhanced resilience to abiotic and biotic stresses and improved productivity. While senescence induces large-scale metabolomic changes, the characterization of metabolic shifts and the identification of key metabolites and pathways determining the staygreen trait remain limited. Here, we generated a temporal map of the physiological and metabolic variation in genetically diverse maize (Zea mays) inbred lines spanning the staygreen spectrum.

Standard QTL mapping approaches consider variant effects on a single gene at a time, despite abundant evidence for allelic pleiotropy, where a single variant can affect multiple genes simultaneously. While allelic pleiotropy describes variant effects on both local and distal genes or a mixture of molecular effects on a single gene, here we specifically investigate allelic expression "proxitropy": where a single variant influences the expression of multiple, neighboring genes. We introduce a multi-gene eQTL mapping framework--principal component expression QTL (-pc eQTL or pcQTL)-to identify variants associated with shared axes of expression variation across a cluster of neighboring genes.

Genome-wide association studies (GWAS) have discovered numerous trait-associated variants, but their biological context remains unclear. Integrating GWAS summary statistics with single-cell RNA-sequencing expression profiles can help identify the cell types in which these variants influence traits. Two main strategies have been developed to integrate these data types.
