Other loci involved in modulation of NF-κB pathway in psoriasis and psoriatic arthritis includes the susceptibility loci TNIP1 gene haplotype (rs2233278), which was identified in Japanese, European, and Chinese populations (Bowes et al., 2011; Callahan et al., 2013; Tamari et al., 2014; Tsoi et al., 2017). This evidence concerns the gene NFKB1 and psoriasis.
