SNP-Flankplus: SNP ID-centric retrieval for SNP flanking sequences

UNLABELLED 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.
