Although no single variant showed an association which was statistically significant at the genome-wide threshold a number represented promising associations – BRCA2:c.9976A>T, p.(Lys3326Ter), which has been shown to influence breast and lung cancer risk (odds ratio (OR)=2.3, P=4.00 × 10−4 for glioblastoma (GBM)) and IDH2:c.782G>A, p.(Arg261His) (OR=3.21, P=7.67 × 10−3, for non-GBM). The gene discussed is IDH2; the disease is lung carcinoma.
