However, no significant correlations were found between serum SERPINB3/4 levels and PAS scores (r = −0.1290, p = 0.4818), P‐NRS scores (r = −0.1927, p = 0.2906), DLQI scores (r = 0.1465, p = 0.4235), PSQI scores (r = −0.1168, p = 0.5244), or HADS scores (r = −0.08574, p = 0.6408) in PN patients (Figure 2b–f). The gene discussed is SERPINB3; the disease is poikiloderma with neutropenia.
