FN1 and androgen insensitivity syndrome: In downstream analysis, the upregulated mRNA in the ceRNA network was combined with drug target molecular information in the Drugbank database to screen and identify three direct targets, NFKBIA, TNFAIP6, and ORM1, all of which play key immunomodulatory and anti-inflammatory roles in the pathological process of AIS; Further combining with the PPI network, FN1 and MMP9 were identified as key predictive targets.
