TERT and breast cancer: The inverse association of TERT Ex2-659G>A (A305A) and two other linked TERT SNPs appeared to be limited to individuals with a family history of breast cancer in first-degree female relatives, −1381C>T (OR 0.73, 95% CI 0.53–1.00), −244C>T (OR 0.66, 95% CI 0.46–0.95), and Ex2-659G>A (A305A) (OR 0.57, 95% CI 0.39–0.84) (Table 2 and Supplementary Table 2).
