Therefore, we performed this study to detect the lnc‐ITSN1‐2 expression in AIS patients and its predictive value for AIS risk, and we discovered that lnc‐ITSN1‐2 expression was elevated in AIS patients compared with the controls, and it exerted a good predictive value for increased AIS risk. This evidence concerns the gene ITSN1 and androgen insensitivity syndrome.
