"Comprehensive Analysis of Circulating Metabolic Biomarkers Across the Genome"

A genome-wide association study involving 233 circulating metabolic traits in over 136,000 participants from 33 cohorts has identified more than 400 independent loci and assigned probable causal genes at two-thirds of these. The study highlights the importance of sample and participant characteristics on genetic associations and demonstrates substantial genetic pleiotropy for multiple metabolic pathways. Ancestry-stratified analyses show positive correlations across ethnic groups, and associations were strongly related to sample size. The study provides a foundational resource for examining the role of metabolism across diverse diseases and emphasizes the need for careful consideration of sample type and fasting status in interpreting results.

Unraveling the Genetic and Epidemiological Landscape of Clonal Hematopoiesis

Clonal hematopoiesis (CH), the expansion of a few clones of hematopoietic stem cells, is associated with reduced life expectancy and increased risk of hematological neoplasia. A study using whole-genome sequencing of blood samples from over 176,000 participants identified 16,306 cases of CH, with a prevalence of 9.3%. CH was more common in older individuals and strongly associated with smoking. CH was also linked to increased risks of myeloid and lymphoid neoplasia, chronic obstructive pulmonary disease, lung cancer, peripheral artery disease, emphysema, and alcohol abuse. However, no significant association was found between CH and cardiovascular disease or inflammatory conditions. Genetic analysis revealed mutations in known myeloid disease genes, as well as novel associations with other genes. The study provides insights into the epidemiology and genetics of CH and its association with various diseases.
