Multi-ancestry whole genome sequencing analysis of lean body mass.
Synthesis in Genome biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundLean body mass is a crucial physiological component of body composition. Although lean body mass has a high heritability, studies evaluating the genetic determinants of lean mass (LM) have to date been limited largely to genome-wide association studies (GWAS) and common variants. Using whole genome sequencing (WGS)-based studies, we aimed to discover novel genetic variants associated with LM in population-based cohorts with multiple ancestries.
resultsWe describe the largest WGS-based meta-analysis of lean body mass to date, encompassing 10,729 WGS samples from six TOPMed cohorts and the Louisiana Osteoporosis Study (LOS) cohort, measured with dual-energy X-ray absorptiometry. We identify seven genome-wide loci significantly associated with LM not reported by previous GWAS. We partially replicate these associations in UK Biobank samples. In rare variant analysis, we discover one novel protein-coding gene, DMAC1, associated with both whole-body LM and appendicular LM in females, and a long non-coding RNA gene linked to appendicular LM in males. Both genes exhibit notably high expression levels in skeletal muscle tissue. We investigate the functional roles of two novel lean-mass-related genes, EMP2 and SSUH2, in animal models. EMP2 deficiency in Drosophila leads to significantly reduced mobility without altering muscle tissue or body fat morphology, whereas an SSUH2 gene mutation in zebrafish stimulates muscle fiber growth.
conclusionsOur comprehensive analysis, encompassing a large-scale WGS meta-analysis and functional investigations, reveals novel genomic loci and genes associated with lean mass traits, shedding new insights into pathways influencing muscle metabolism and muscle mass regulation.
