Database Description

PAHdb is a relational locus-specific mutation knowledgebase for the human phenylalanine gene (symbol PAH) and all its associated information. It is accessible through the web ( Genotype/phenotype correlations, haplotype associations and population distributions, along with in-vitro expression analysis data, are among the searchable data in PAHdb. Annotated auxiliary modules exist dealing with sequences, mutation mapping, haplotypes, three-dimensional modelling of the PAH enzyme molecule (including high-resolution stills and live animation), and genetic models of the phenylalanine gene (Pah) in the mouse. PAHdb is disease-oriented, focusing on hyperphenylalaninemia (HPA) (OMIM 261600), which results from a primary deficiency of PAH enzyme function (EC; information for patients affected by HPA is available in the form of an up-to-date clinical resource booklet, while clinicians have access to the entry for PAH deficiency in the peer-reviewed GeneClinics internet resource ( Links pertaining to PAH - OMIM, the Scripps Model (, GenBank entries, etc.- are also included and periodically updated. Interaction with the knowledgebase, especially in the area of mutation submission by users, has been enhanced through a new 'user-friendly' interface. The PAHdb schema is now widely accepted as the template for the design and implementation of locus-specific mutation databases (LSDBs). Initial ventures by the community towards a comprehensive repository of allelic variation can use PAHdb, as a mature working implementation of accepted database structure and allele nomenclature guidelines. An algorithm (Teebi S and Scriver CR unpublished) permits data to be retrieved from this and any other LSDB and integrated into the proposed comprehensive (genomic) human mutation database.
