In an attempt to identify additional susceptibility loci in Chinese patients with lung cancer, Dong et al. [30] reported genome-wide significance for three additional lung cancer susceptibility loci at 10p14 (close to GATA3), 5q32 in PPP2R2B-STK32A-DPYSL3, and 20q13.2 in CYP24A1. They also found additional associations for rs247008 at 5q31.1 (IL3-CSF2-P4HA2), and rs9439519 at 1p36.32 (AJAP1-NPHP4). This evidence concerns the gene P4HA2 and lung carcinoma.
