KPNA3 and COVID-19: We used the publicly available RNA sequencing dataset GSE152075 to evaluate the expression of the importin family genes (Importin α5 (KPNA1), Importin α1 (KPNA2), Importin α4 (KPNA3), Importin α3 (KPNA4), Importin α6 (KPNA5), Importin α7 (KPNA6), Importin α8 (KPNA7), and Importin β1 (KPNB1)) in COVID-19 positive and negative patients (Figure 1A).
