NCBI now hosts GeneReviews and GeneTests, two resources developed by a team led by Roberta A. Pagon, University of Washington. GeneReviews (www.ncbi.nlm.nih.gov/bookshelf/br.fcgi?book=gene) is a compendium of continually updated, expert-authored and peer-reviewed disease descriptions that relate genetic testing to the diagnosis, management and genetic counseling of patients and families with specific inherited conditions (7,8). These reviews can be searched via the GeneReviews tab at the GeneTests home page (www.ncbi.nlm.nih.gov/sites/GeneTests/), NCBI’s Bookshelf site, NCBI’s All Databases interface or major web search engines.
