While OR2AT4 is not a DEG in our analysis or in previous studies [5, 31, 32] and is not a member of a module significantly correlated with psoriasis in PPvNN or PPvPT, we nonetheless observed that the salmon module was significantly enriched for olfactory signaling and transduction canonical pathways, a finding that bolsters our previous analysis of this data using a complementary coexpression analysis method [21]. The gene discussed is OR2AT4; the disease is psoriasis.
