Identification of foreign gene sequences by transcript filtering against the human genome

Nat Genet. 2002 Feb;30(2):141-2. doi: 10.1038/ng818. Epub 2002 Jan 14.


We have developed a computational subtraction approach to detect microbial causes for putative infectious diseases by filtering a set of human tissue-derived sequences against the human genome. We demonstrate the potential of this method by identifying sequences from known pathogens in established expressed-sequence tag libraries.
