Fig 1 shows the microarray and qRT-PCR gene expression levels for CCL20 and CCR6. Compared to N, CCL20 is clearly overexpressed in both UCa (log2 ratio 2.43 with fold change 5.39, p<0.001) and CDa (log2 ratio 2.08 with fold change 4.23, p<0.001). The same is seen for CCR6 in UCa (log2 ratio 0.87 with fold change 1.83, p<0.001) and CDa (log2 ratio 1.01 with fold change 2.01, p<0.001). This evidence concerns the gene CCL20 and congenital dyserythropoietic anemia.
