lncRNASNP is an integrated database of SNPs in lncRNAs and their potential functions in human and mouse. It integrated several public databases and tools, including LNCipedia, NONCODE, dbSNP, miRBase, TCGA and so on. Its aim is to provide information of SNPs in lncRNAs, structure change by SNP, the binding sites of lncRNA:miRNA and potential functional SNPs which can impact lncRNA:miRNA interaction. In addition, lncRNASNP also integrates GWAS data and miRNA expression data into functional SNP selection for genetic association studies. Currently, users can:Browse or search SNPs in lncRNAs and their impacts on RNA secondary structure; Browse or search miRNA binding sites in lncRNAs; Browse or search SNPs impacting the interaction of miRNA:lncRNA (loss or gain);Browse or search SNPs in GWAS linkage disequilibrium (LD) regions;Browse or search miRNA expression data to prioritize functional SNP selection.
