A case-control study further elaborated the relationship between the TP53 codon 72 polymorphism and SCZ risk (Lung et al., 2009), whereas TP53 alleles carrying BstUI (exon 4) and MspI (intron 6) restriction sites were shown to confer greater susceptibility to lung cancer in Turkish patients with SCZ (Ozbey et al., 2011). This evidence concerns the gene TP53 and lung cancer.
