PAHdb (http://www.mcgill.ca/pahdb ) is a curated relational database (Fig.
1) of nucleotide variation in the human PAH cDNA (GenBank U49897). Among
328 different mutations by state (Fig. 2) the majority are rare mutations
causing hyperphenylalaninemia (HPA) (OMIM 261600), the remainder are
polymorphic variants without apparent effect on phenotype. PAHdb modules
contain mutations, polymorphic haplotypes, genotype-phenotype correlations,
expression analysis, sources of information and the reference sequence; the
database also contains pages of clinical information and data on three ENU
mouse orthologues of human HPA. Only six different mutations account for
60% of human HPA chromosomes worldwide, mutations stratify by population
and geographic region, and the Oriental and Caucasian mutation sets are
different (Fig. 3). PAHdb provides curated electronic publication and one
third of its incoming reports are direct submissions. Each different
mutation receives a systematic (nucleotide) name and a unique identifier
(UID). Data are accessed both by a Newsletter and a search engine on the
website; integrity of the database is ensured by keeping the curated
template offline. There have been >6500 online interrogations of the
website.
