This case-control association study analyzed 10 telomere-length-associated SNPs in relation to pancreatic cancer risk in 2,374 cases and 4,326 controls from the PANDoRA consortium. The strongest association was with TERT-rs2736100 (OR=1.54, p=1.54×10⁻¹⁰), and a novel protective association was found with NAF1-rs7675998 (OR=0.80, p=1.87×10⁻⁶). A genetic telomere length score (teloscore) combining these variants reached genome-wide significance for PDAC risk (p=2.98×10⁻⁹ for highest vs. lowest quintile).

Mendelian randomization study of 16 genetic variants in 10 telomere-related loci using summary data from 420,081 cancer cases and 1,093,105 controls. Genetically increased telomere length was associated with higher cancer risk (glioma OR 5.27 [3.15-8.81], lung adenocarcinoma 3.19 [2.40-4.22], neuroblastoma 2.98 [1.92-4.62]) but reduced risk for cardiovascular diseases and some immune conditions.
