Single nucleotide polymorphisms(SNPs) are an important tool to study genetic variations.We present CGDSNP, a high quality mouse SNP database with more than 8 Millions SNPs from 97 strains of laboratory mice, drawn from several sources. You can search for SNP by genome location,gene Annotations,SNP amino acid implication, minor allele frequency,strains,SNP source (see:Database Report) Please provide feedback
