About SNV-MWAS

Gut microbes contain millions of single nucleotide variants (SNVs), and their association with environmental exposome and human health is under-explored.

By focusing on core-genome common SNVs in the gut microbiome, we identified 49,346 study-wide significant associations (Pmeta-analysis < 5.42 × 10⁻¹¹) through meta-analysis, linking 39,663 SNVs from 101 gut microbial species to 69 human phenotypes and exposure factors. These findings provide strain-level mechanistic hypotheses regarding microbial functionality in human health. Full details are available in our preprint at Research Square.
