Twelve cancer-associated genes mapping in six of these regions were identified to be altered: the INPP5A (at 10q26.3), CDX1, CAMK2A (at 5q32), MB and APOL6 (both at 22q13.1) genes among the former (group 1) cases, and the SFRS13A (1p36.11), VPS53, FAM57A, GEMIN4, ELP2P and GLOD4 (all of them at 17p13.3) and the CSF2RA and the IL3RA (both at Xp22.33) genes, all deleted among group 2 cases (Figure 1) . This evidence concerns the gene IL3RA and cancer.
