Genomic Structural Variations in Bacteria Linked to Autism in Children as Potential Diagnostic Indicators

  • 1

    The study identified 100 bacterial genomic structural variations (SVs) significantly associated with autism spectrum disorder (ASD).

  • 2

    Distinct bacterial SV signatures linked to ASD were associated with metabolic dysregulation and gut dysbiosis commonly observed in affected children.

  • 3

    Critical SVs in Bacteroides uniformis were shown to regulate thiamine and iron metabolism, correlating with ASD-related behaviors.

  • 4

    A diagnostic panel combining nine SVs and three bacterial species achieved an accuracy of 81.1% in distinguishing ASD from neurotypical children.

  • 5

    The findings suggest potential for microbial genomic SV-based biomarkers in diagnosing childhood ASD and understanding its pathogenesis.
