Transcripts with significant differences of expression levels between normal scrotum and CAIS labia majora. Transcript levels of 612 genes identified by SAM analysis as differing between fibroblasts derived from normal male scrotum (green) and labia majora of 46, XY females with CAIS (pink). Individual transcripts are grouped by hierarchical cluster analysis and are displayed in rows while experiments are represented in columns. Expression values per gene are centered by the mean log2 red/green normalized ratio. Increasing red intensity corresponds to higher relative transcript levels compared to the mean expression level across all 15 array experiments. Increasing green intensity corresponds to relatively decreased transcript levels compared to the mean. On the right side, examples of individual genes (gene symbols according to S.O.U.R.C.E. ) discussed in the paper or falling into the biological processes and cellular pathways detected by PANTHER are displayed. Detailed data on figure 1 is available in additional files 1, 2, 3, 4.
