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]
