Given that HNRNPA2B1 and HNRNPC were associated with the severity of EMs in EU samples, we selected these two molecules to evaluate their diagnostic value when compared to MKI67, CDH1 (E-cadherin), ACTA2 (α-SMA), PGR, ESR1, and ESR2, in EMs tissue samples. Here, ESR2 is linked to eosinophilia-myalgia syndrome.
