This region encompassed several genes among others DHRS4L2, REC8L1, IPO4, PSME1 and PCK2. One tumor (case 25) displayed gain of entire chromosome 14, and four tumors (1, 20, 23, 27M) carried partial or small gain of 14 without harboring copy number losses on chromosome 18. This evidence concerns the gene IPO4 and neoplasm.
