NFKB1 and biliary atresia: Among these transcription factors we highlight the sites for nuclear factor of activated T-cells (NFAT; 65 genes, P < 0.001) and nuclear factor (NF)kB (60 genes, P < 0.001; Figure 6a; Additional file 6) because both regulate immunity genes, but only the pleiotropic transcription factor NFkB being previously linked to biliary atresia [29,30].
