Because the algorithms are making estimates of the best possible alignments, you may have errors pop up due to rare SNPs or an INDEL. There is a SNP BLAST search, however. In addition, if your query word “neighborhood” search includes too many three word combinations, you’ll end up with sequences that really aren’t as similar as you hoped.
