Genome-wide screening for genetic loci associated with risk of lung adenocarcinoma (ADCA) was carried out in pooled DNA using the Illumina 300K single-nucleotide polymorphism (SNP) array, in a joint analysis of 2 Italian case-control series matched by age, gender and smoking habit. The rare allele carrier status of 8 SNPs was associated with a decreased lung ADCA risk [odds ratios (OR): 0.6-0.8]. In a polygenic model characterized by additive and interchangeable effects, individuals carrying 2 to 6 rare alleles at these 8 SNPs showed a significant trend toward a decreased risk of lung ADCA (up to OR of 0.3). These results suggest the relevance of a polygenic model in the modulation of individual risk of lung ADCA in the general population.
