{"doi":"10.1101/2022.03.08.22272044","title":"A non-coding single nucleotide polymorphism at 8q24 drives IDH1-mutant glioma formation","abstract":"Abstract Establishing causal links between inherited polymorphisms and cancer risk is challenging. Here, we focus on the single nucleotide polymorphism rs55705857 (A>G), which confers a 6-fold increased risk of IDH-mutant low-grade glioma (LGG) and is amongst the highest genetic associations with cancer. By fine-mapping the locus, we reveal that rs55705857 itself is the causal variant and is associated with molecular pathways that drive LGG. Mechanistically, we show that rs55705857 resides within a brain-specific enhancer, where the risk allele disrupts OCT2/4 binding, allowing increased interaction with the Myc promoter and increased Myc expression. To functionally test rs55705857, we generated an IDH1 R132H -driven LGG mouse model and show that mutating the highly conserved, orthologous mouse rs55705857 locus dramatically accelerated tumor development from 463 to 172 days and increased penetrance from 30% to 75%. Overall, our work generates new LGG models and reveals mechanisms of the heritable predisposition to lethal glioma in ∼40% of LGG-patients.","journal":"medRxiv","year":2022,"id":298186,"datarank":0.29188652235829704,"base_score":1.9459101490553132,"endowment":1.9459101490553132,"self_citation_contribution":0.29188652235829704,"citation_network_contribution":0.0,"self_endowment_contribution":0.29188652235829704,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":6,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9576,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2022-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":414218,"name":"Kristen Drucker","orcid":"0000-0001-6244-5863","position":1,"is_corresponding":false},{"id":414219,"name":"Thomas M.
