A colleague asked me a simple question for which I've yet to find a simple solution. The FASTA files for many mouse strains have been sequenced and assembled. He'd like to download the sequence of a given gene in a specific strain (e.g., TP53 in A/J). That Sanger page provides easy tools to look at variation, but I just want a plain FASTA file. I was hoping there would be a BioMart instance but no luck, and the main BioMart Central doesn't appear to have anything relevant.
I'm still hoping there's a user-friendly web tool out there that I'm just missing. If not that, then a bioinformatics solution that is easier than creating a BLAST database, blasting B6 sequences to get coordinates, and then fastacmd to get subsequences. Solutions for the lazy bioinformatician are appreciated!
