Application of hsa-miR-4712-3p as molecular marker and kit

The invention relates to a miRNA (micro Ribonucleic Acid) biomarker combination for diagnosing or assisting in screening a high altitude headache (HAH) susceptible person and a kit of the miRNA biomarker combination, and relates to the technical field of microRNA molecular detection. By extracting miRNA in plasma of HAH and a healthy control group for expression level detection and comparison, the result shows that compared with the healthy control group, hsa-miR-4712-3p expression of a HAH susceptible person in plasma and saliva specimens is remarkably up-regulated compared with the expression in the control group, the method has statistical significance in difference between the HAH susceptible person and the healthy control group, and the method has a good application prospect. The method has good diagnostic efficiency, is suitable for large-scale screening of HAH susceptible persons in plains, and prevents the onset risk of HAH after entering plateau. 本发明涉及本发明公开了一种用于诊断或辅助筛查高原头痛(high altitude headache，HAH)
