    This study identifies a four-miRNA exosomal signature as a non-invasive diagnostic tool for central precocious puberty (CPP).

  • 2

    The diagnostic model achieved an AUC of 0.912, with 91.3% sensitivity and 88.9% specificity in distinguishing CPP patients from healthy controls.

    The four candidate miRNAs were hsa-miR-6747-3p, hsa-miR-6873-5p, hsa-miR-615-3p, and hsa-miR-6886-3p, validated through qRT-PCR.

    Bioinformatics analysis revealed significant enrichment of the GnRH signaling pathway, linking the miRNA signature to key regulatory genes.

  • 5

    This research provides a foundation for precision diagnostics in pediatric endocrinology, moving away from invasive testing methods.
