When we analysed the allele frequencies of the icb-1 gene SNPs we found that in women with ovarian cancer the A allele of SNP rs1467465 was carried significantly more often than in women without an ovarian malignancy (0.40 vs. 0.33, OR 1.37, 95% CI 1.013-1-853, p = 0.04) (Table 3). Here, THEMIS2 is linked to ovarian cancer.
