When analysis was restricted to the 6,500 patients with invasive serous adenocarcinomas, the magnitude of association was slightly attenuated for ADAR3 rs77027562 (OR = 1.33, P = 6.1×10−3) and slightly stronger for SND1 rs185455523 (OR = 0.60, P = 1×10−4). This evidence concerns the gene ADARB2 and serous adenocarcinoma.
