Genes implicated in separation of MF immunohistochemical/histologic subgroups. (A) A total of 11 genes that are significant in the separation of common phenotype and aberrant phenotype cases were identified, 10 of which are up-regulated in aberrant phenotype cases, with one EST (Hs.199961) down-regulated in aberrant phenotype cases. (B) A total of 5 genes significant in the separation of tumor stage disease from plaque stage disease were identified, all 5 of which are down-regulated in cases with tumor stage disease.
