Common variation at 2p13.3, 3q29, 7p13 and 17q25.1 associated with susceptibility to pancreatic cancer
Menée sur 9 925 cas de cancer du pancréas et 11 569 témoins, cette étude d'association sur le génome entier identifie quatre loci, situés sur les régions chromosomiques 2p13.3, 3q29, 7p13 et 17q25.1, en association avec une susceptibilité à la maladie
Pancreatic cancer is the fourth leading cause of cancer death in the developed world. Both inherited high-penetrance mutations in BRCA2 (ref. 2), ATM3, PALB2 (ref. 4), BRCA1 (ref. 5), STK11 (ref. 6), CDKN2A and mismatch-repair genes and low-penetrance loci are associated with increased risk. To identify new risk loci, we performed a genome-wide association study on 9,925 pancreatic cancer cases and 11,569 controls, including 4,164 newly genotyped cases and 3,792 controls in 9 studies from North America, Central Europe and Australia. We identified three newly associated regions: 17q25.1 (LINC00673, rs11655237, odds ratio (OR) = 1.26, 95% confidence interval (CI) = 1.19–1.34, P = 1.42 × 10−14), 7p13 (SUGCT, rs17688601, OR = 0.88, 95% CI = 0.84–0.92, P = 1.41 × 10−8) and 3q29 (TP63, rs9854771, OR = 0.89, 95% CI = 0.85–0.93, P = 2.35 × 10−8). We detected significant association at 2p13.3 (ETAA1, rs1486134, OR = 1.14, 95% CI = 1.09–1.19, P = 3.36 × 10−9), a region with previous suggestive evidence in Han Chinese12. We replicated previously reported associations at 9q34.2 (ABO)9, 13q22.1 (KLF5)10, 5p15.33 (TERT and CLPTM1)10, 11, 13q12.2 (PDX1)11, 1q32.1 (NR5A2)10, 7q32.3 (LINC-PINT)11, 16q23.1 (BCAR1)11 and 22q12.1 (ZNRF3)11. Our study identifies new loci associated with pancreatic cancer risk.
