CDKN2A and lung cancer: Two regions of unique focal deletions (q-value = 0.085 and 0.0064, respectively) included (1) 13p12 containing HKR1 and (2) 5q33.3 containing CD74. Besides that, we also found unique deletions of 6p21.2 containing CDKN2A, 11q12.3 containing SCYL1, 1q21.1 containing NTRK1 and MDM4, and 9q33.2 containing PRDM1. It was found that the gain in 5p15.33 was one of the regions that reproducibly associates with lung cancer risk [53] and the gain in 20q13.33 was the main chromosomal abnormalities in colorectal carcinoma [54].
