Raises a question worth testing. It does not answer one.
This is a hypothesis-generating genome-wide analysis identifying shared genetic variants and biological pathways between obesity and COVID-19 severity using a conjunctional false discovery rate approach on public GWAS data. The work implicates immune, metabolic, and hormonal signaling in the obesity–COVID-19 association but does not establish causal mechanisms or clinical implications without experimental or clinical validation.
Genome-wide association study with conjunctional false discovery rate analysis, functional annotation, pathway enrichment, and phenome-wide association study. Population-level genomic data from public GWAS databases; no direct human cohort described.. Intervention: Computational analysis of shared genetic variants between BMI and COVID-19 phenotypes.
Shared variants enriched in immune, metabolic and hormonal signaling pathways, including metal ion transport and glycosylation Genetic overlap with BMI was strongest for hospitalized and severe COVID-19 cases, suggesting common mechanisms in disease progression rather than infection alone
Safety was not reported in the material analysed. Check the source before drawing any conclusion about harm.
These findings suggest potential shared biological pathways but do not provide actionable clinical guidance or validated therapeutic targets. Functional validation and mechanistic studies would be needed before clinical translation.

Abstract COVID-19 and obesity are complex conditions marked by immune and metabolic dysfunction, with the former still ranking among the leading causes of death from infectious diseases worldwide and the latter reaching pandemic proportions. Clinical evidence consistently shows that obesity increases the risk of severe COVID-19, yet the biological mechanisms underlying this association remain unclear. Given their physiological and clinical overlap, they may share genetic pathways. We investigated genetic variants jointly associated with body mass index (BMI) and COVID-19 using publicly available genome-wide data. A conjunctional false discovery rate (conjFDR) approach identified shared variants between BMI and three COVID-19 phenotypes: infection, hospitalization and very severe respiratory illness. Functional annotation and pathway enrichment analyses were performed to explore the biological context of these variants, followed by a phenome-wide association study (PheWAS) to characterize pleiotropy. Shared variants were enriched in immune, metabolic and hormonal signaling pathways, including metal ion transport and glycosylation. The overlap with BMI was strongest for hospitalized and severe cases, suggesting common mechanisms underlying disease progression rather than infection. These findings suggest a biologically meaningful genetic overlap between obesity and COVID-19 severity, highlighting pleiotropy as a key feature in complex disease interactions and potential shared therapeutic targets.
