While the role of miR-30a-3p in EoE remains unstudied, our literature review and miRNA target analysis indicated that miR-30a-3p targeted RUNX2 [52], CCR3 [53], and RTP4 (Table S3)—three genes that are robustly upregulated in biopsies from patients with active EoE and serve as diagnostic markers [54,55]. The gene discussed is RUNX2; the disease is eosinophilic esophagitis.
