This study identifies 26 key genes linked to tuberculosis (TB) risk by integrating genetic and gene expression data. These findings offer new insights into the genetic basis of TB susceptibility.
Area of Science:
- Genomics
- Immunology
- Infectious Diseases
Background:
- Genome-Wide Association Studies (GWAS) have identified numerous genetic loci associated with tuberculosis (TB).
- The functional impact of these genetic variants on TB susceptibility remains largely unexplored.
Purpose of the Study:
- To conduct an integrative genomics analysis to identify single nucleotide polymorphisms (SNPs) and genes implicated in TB risk.
- To prioritize candidate genes by assessing their association with both gene expression and TB susceptibility.
Main Methods:
- Integrated a large GWAS dataset (N=452,264) with eQTL datasets (N=2,242) and other omics data.
- Performed biological and technical validations to prioritize candidate genes.
- Utilized network-based enrichment analysis and differential gene expression analysis across multiple datasets.
Main Results:
- Prioritized 26 candidate genes, including CDC16 and RCN3, with eSNPs associated with both gene expression and TB susceptibility.
- Demonstrated that these 26 genes are interconnected and jointly influence TB susceptibility.
- Observed significant differential expression of 21 out of 26 genes (80.77%) in various tissues and cell types between TB patients and controls.
Conclusions:
- Provided robust evidence supporting 26 genes as critical candidates for TB.
- Highlighted the functional role of genetic variants in TB pathogenesis through gene expression modulation.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
