CCL26 and nail-patella syndrome: Conversely, in NP (Figure 3d), this analysis showed the existence of two sample clusters: one cluster characterized by lower expression of CCL26 and high expression of SAA2 (putative non‐eosinophils, NEC‐NPs) and a second cluster characterized by higher expression of CCL26, and low expression of SAA2 (putative eosinophils, EC‐NPs).
