Two of the 93 genes were found to be tumor-site specific: PLEKHC1 (pleckstrin homology domain containing, family C [with FERM domain] member 1) and SGCB (sarcoglycan beta) transcripts were detected only in ovarian cancer patients (see Additional file 4), although they were also detected in cancer cell lines of breast and endometrial origin either. This evidence concerns the gene SGCB and ovarian carcinoma.
