CYP3A4 and psoriasis: The genotypic data of the 49 patients propose an association with the response to apremilast of (i) sixty-four SNPs within or near PDE4 and CYP3A4 genes, (ii) three SNPs within the ANRIL and LINC00941 lncRNAs and one SNP inside miR4706 and (iii) thirty-three SNPs within genes encoding protein components of the PDE4 interactome or cAMP signaling pathway relevant to psoriasis.
