Investigating HARs in Neurodevelopment via Host–Microbe–Metabolite Interactions: A Computational Protocol v1

Human Accelerated Regions (HARs) are rapidly evolved genomic loci thought to contribute to human-specific traits, including brain development. Recent studies suggest that some HAR-associated genetic factors may influence the composition of the gut microbiome, hinting at co-evolution between human genomes and commensal microbes. The following protocol outlines a multi-step computational workflow to explore how HARs might impact neurodevelopmental processes through host–microbe–metabolite interactions. This integrative approach combines genomic analyses, microbial data mining, metabolomic pathway enrichment, pharmacokinetic predictions, network biology, and evolutionary context mapping.
