摘要: There are two main types of lung cancer: small cell cancer (SCLC) and non-small (NSCLC). NSCLC has many subtypes, but the most common adenocarcinoma (LUAD) squamous carcinoma (LUSC). These subtypes mainly classified by physiological pathological characteristics, although there is increasing evidence genetic molecular differences as well. Although some work been done at somatic level to explore biological among little that interrogates these germline characterize unique shared susceptibility genes for each subtype. We used single-nucleotide polymorphisms (SNPs) from a genome-wide association study (GWAS) European samples interrogate similarity SNP, gene, pathway, regulatory levels. expanded genotyped SNPs include all in linkage disequilibrium (LD) using data 1000 Genomes Project. mapped several tissue expression quantitative trait loci (eQTL) enhancer datasets identify their target genes. perform pathway analysis identified 8295, 8734, 8361 with moderate signals LUAD, LUSC, SCLC, respectively. Those had p 0.8, Europeans) SNPs. 215, 320, 172 disease-associated Only five (CHRNA5, IDH3A, PSMA4, RP11-650 L12.2, TBC1D2B) overlapped subtypes. Furthermore, we observed only pathways Kyoto Encyclopedia Genes At level, three eQTL between Our results suggest do not share much signal or which differs subtype classification based upon histology. However, PSMA4) well-known may act general regardless
