Welcome to the miRNASNP database

MicroRNAs (miRNAs) are endogenous and regulatory non-coding RNAs by targeting mRNAs for cleavage or translational repression. SNPs in pre-miRNAs or target sites will affect miRNA function and be related with diseases or biological processes. miRNASNP aims to provide a resource of the miRNA-related SNPs, which includes SNPs in pre-miRNAs of human and other species, and target gain and loss by SNPs in miRNA seed regions or 3'UTR of target mRNAs.

New features in miRNASNP V2
