Extraction of Sequences from SNP entries
The NCBI SNP database contains information on all different single nucleotide polymorphisms. Each position is indicated by a SPDI entry number, and each of these corresponds to a particular position in the human genome (and a particular variation). To save time in going from a SNP database query and a bunch of sequences, you can use the below tools. The webform below is useful for preliminary studies and small batches, while the downloadable Java based program can be used to query the entire SNP database. The Java program also allows for renaming the point that has been mutated (such as Y, for a C to T mutation). The program is tentatively called 'Gavin Project', as it was developed for a student's independent study research project. It may be renamed in the future.
Due to the nature of how the databases are accessed, in this program you can get the SPDI numbers, and even the nucleotide positions, in batches. The sequences must be obtaind 'semi-automatically', by successivelly clicking the 'Get Flanking Sequence' button until the counter fails to increase.
