One other SNP rs3753348 showed association with a more than three-fold risk with survival in mucinous ovarian cancer (Table 2); this SNP resides in the 5 kb region between tumor necrosis factor receptor superfamily members 4 and 18 (TNFRSF4 and TNFRSF18) on chromosome 1. Here, TNFRSF18 is linked to mucinous ovarian cancer.
