title: SNP-Flankplus: SNP ID-centric retrieval for SNP flanking sequences.
abstract: The flanking sequences provided by dbSNP of NCBI are usually short and fixed length without further extension, thus making the design of appropriate PCR primers difficult. Here, we introduce a tool named "SNP-Flankplus" to provide a web environment for retrieval of SNP flanking sequences from both the dbSNP and the nucleotide databases of NCBI. Two SNP ID types, rs# and ss#, are acceptable for querying SNP flanking sequences with adjustable lengths for at least sixteen organisms.
