Most of these genes (CD24, EPHB2, FABP5, HPSE, KYNU, OAS3, OASL, PRSS27, SAMD9, SERPINB13, STAT1, TMPRSS11D) were also identified in hub genes of the module most associated with psoriasis progression in external datasets GSE6710/GSE14905 (S3 Table). This evidence concerns the gene OAS3 and psoriasis.
