rs1801270 is a SNP known as p21 codon 31, although the gene now known to code for the p21 protein is termed CDKN1A, and has also been known as WAF1 and CIP1. Along with p53 codon 72 (rs1042522), it is one of the best studied SNPs due to its role in increased tumor susceptibility (and thus cancer).
A study of ~150 lung cancer patients in Sweden found that the rs1801279(A) allele, encoding the amino acid Arg at codon 31, represented the risk allele (odds ratio 1.7, CI: 1.0-2.9), compared to healthy individuals. The difference was even more striking when compared to patients with chronic obstructive pulmonary disease (COPD), in which case the odds ratio was over 5.[PMID 8807325]
