STN1 and prostate cancer: Another study of similar design (albeit smaller and more limited coverage) (23), found genome-wide statistical significance for association between mean telomere length and TERC, TERT, OBFC1, a novel locus at 3p14.4, and support for ACYP2, NAF1, and RTEL1. Of these, only TERT was associated with risk of breast, ovarian, and prostate cancer, while OBFC1 was associated with a subtype of ovarian cancer.
