Table 2.

Genes selected from microarray analysis. Gene symbol and Affymetrix ID are listed. The first 8 transcripts were selected by PAM analysis. *= transcripts not included in PAM analysis, but selected for potential interest. Fold change represents the change in microarray gene expression comparing SSc‐PAH gene expression to SSc without PAH gene expression. p value is the statistically significant difference in the microarray analysis gene expression comparing SSc‐PAH to SSc without PAH. LRRN3 is counted as two transcripts.
