IFNA1 and peeling skin syndrome: In patients with pSS, a positive correlation was observed for fractions of CD19+ B cells and monocytes (R=0.21, pdiscovery=0.039 and R=0.28, pdiscovery=6.6x10-3, respectively), while the fraction of NK cells was found to correlate negatively with the IFN score (Rdiscovery=–0.23, pdiscovery=0.022) (Figure 1D and Supplementary Figure S2A).
