Chromosome 1p36 deletion has been observed in approximately 36 % of primary tumors and several studies indicate this region containing more than one NB suppressor genes including Tumor Protein p73 (TP73) (1p36.32) [48], cyclin-dependent kinase 11B (CDK11B) (1p36.33) [49], neuroblastoma 1, DAN family BMP antagonist (NBL1) (1p36.13) [50] and paired box 7 (Pax7) (1p36.13) [51]. This evidence concerns the gene PAX7 and neuroblastoma.
