Heat map representing the expression profiles of the top 75 PPP/PPPP specific (A) and psoriasis specific (B) genes. The psoriasis PPP (P) specific genes are those that are differentially expressed in the PPP/PPPP versus normal acral skin and not differentially expressed in the psoriasis versus normal non-acral skin (FDR<0.05; FCH>2 in both comparisons). Likewise psoriasis specific genes are those that are differentially expressed in psoriasis as compared with normal non-acral skin but are not differentially expressed in the PPP/PPPP versus normal acral skin comparisons. In both cases the top 75 are selected based on the largest differences observed between the log2FCH of the PPP/PPPP vs acral and the psoriasis versus non-acral skin comparison. The expression of several genes, including ADAM23 and GPRIN, is higher in PPP/PPPP (lower left portion of Fig 5A) Genes are presented according to an unsupervised cluster analysis. Yellow-red scale: red represents low gene expression and yellow high gene expression.
