Although this specific variant was not associated with HNF1B expression levels in 182 HGS ovarian cancer samples (p = 0.2032) (Supplementary Table 8A), it was borderline significant in a much smaller set of 21 clear cell ovarian cancer patients (p = 0.0732) (Supplementary Table 8B) based on gene expression array data from samples genotyped as part of the Collaborative Oncological Gene-environment Study (COGS)[9]. Here, HNF1B is linked to ovarian clear cell cancer.
