Expression data from pheochromocytoma (PHEO) and paraganglioma (PGL) tumor samples

ABSTRACT: Genotype specific differences in expression profiles have been evaluated using human HuGene1.0-ST Gene Chips. In this dataset we include expression data obtained from 8 normal adrenal medulla and 45 PHEOs/PGLs patient samples. Viable appearing tissue from the center of the lesions was collected and snap frozen for RNA extraction. Each of the 45 PHEO/PGL samples was examined by pathologist upon resection. Patients PKh_27 and PKh_28 with SDHB mutation were from the same patient with samples taken from two different locations at different times. Diagnosis of PHEO/PGL has been confired in all cases histopathologically. The tissues were grouped according to genetic/syndromic background and tumor location into SDHB (n = 18), SDHD-A/T (n = 6), SDHD-HN (n= 8), and VHL (n = 13). Microarray analysis
