Nedoszytko et al. (2007) analyzed 166 patients with psoriasis (134 with type I and 32 with type II) and 65 healthy controls [28] and found similar results to those of Reich et al. [27], with a higher prevalence of the A allele in rs361525 and lower frequency of the A allele in rs1800629 (TNFα gene) in Caucasian patients than in controls (Table 1) [28]. The gene discussed is TNF; the disease is psoriasis.
