J Mol Biol. 2021 May 28;433(11):166709.http://hdl.handle.net/10668/16600Genetic variation, gene expression and DNA methylation influence each other in a complex way. To study the impact of sequence variation and DNA methylation on gene expression, we generated geno5mC, a database that contains statistically significant SNP-CpG associations that are biologically classified either through co-localization with known regulatory regions (promoters and enhancers), or through known correlations with the expression levels of nearby genes. The SNP rs727563 can be used to illustrate the usefulness of this approach. This SNP has been associated with inflammatory bowel disease through GWAS, but it is not located near any gene related to this phenotype. However, geno5mC reveals that rs727563 is associated with the methylation state of several CpGs located in promoter regions of genes reported to be involved in inflammatory processes. This case exemplifies how geno5mC can be used to infer relevant and previously unknown interactions between described disease-associated SNPs and their functional targets.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/DNA methylationSNPsgene regulationCpG IslandsDNA MethylationDatabases, GeneticGenome, HumanHumansInflammatory Bowel DiseasesPolymorphism, Single NucleotidePromoter Regions, GeneticSearch Engineresearch article33188782open accessBases de datos genéticasEnfermedades inflamatorias del intestinoGenoma humanoHumanosIslas de CpGMetilación de ADNMotor de búsquedaPolimorfismo de nucleótido simpleRegiones promotoras genéticas10.1016/j.jmb.2020.11.0081089-8638https://doi.org/10.1016/j.jmb.2020.11.008
