Although laparoscopy remains the gold standard for diagnosis, highlighting the need for non-invasive biomarkers. Haplotype expression of specific miRNAs acts as a circulating signature in both healthy and disease states, including endometriosis. However, their applicability in Hispanic populations has been unexplored.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>This study evaluated the discriminatory capacity of a miRNA expression haplotype in the blood plasma of a Hispanic cohort with laparoscopic confirmed diagnosis (15 patients with endometriosis and 7 from a reference group). The expression levels of miR-451a, miR-3613, miR-125b, let-7b, miR-150, and miR-342 were quantified using qRT-PCR, and their diagnostic performance was assessed through individual ROC curves and multivariate classification models: Logistic regression, CRT, and stacking-based ensemble model.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The miRNA expression haplotype demonstrated high diagnostic accuracy with logistic regression (AUC\u2009=\u20090.914), CRT (AUC\u2009=\u20090.990), and an ensemble model using stacking (AUC\u2009=\u20090.990). Individually, miR-451a (AUC\u2009=\u20090.79), miR-3613 (AUC\u2009=\u20090.714), and let-7b (AUC\u2009=\u20090.667) were the most relevant markers and demonstrated more relevance in the expression haplotype.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>These findings suggest that a miRNA-based diagnostic panel could provide a highly sensitive and specific alternative for diagnosing endometriosis in Hispanic populations. However, validation in larger cohorts is essential to confirm reproducibility and assess its clinical utility in different healthcare settings.<\/jats:p><\/jats:sec>","DOI":"10.3389\/frph.2025.1663755","type":"journal-article","created":{"date-parts":[[2025,9,25]],"date-time":"2025-09-25T05:30:42Z","timestamp":1758778242000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["miRNA
