Batalla et al. corroborated the association between the FCGR3A-158FF polymorphism and anti-TNF response (PASI 75 at week 24) in a study with 115 biologic-naive Spanish patients diagnosed with moderate-to-severe psoriasis (OR = 12.05, CI95% = 1.25–111.11, p = 0.04), although the association between the FCGR2A-131HH allele and anti-TNF response was not confirmed (p = 0.1) [104]. The gene discussed is TNF; the disease is psoriasis.
