The PAH Mutation Analysis Consortium (81 investigators, 26 countries) is engaged in mutation detection at the human PAH locus. Ascertainment of probands occurs largely through newborn screening for hyperphenylalaninemia. A relational database records allelic variation (disease-producing and polymorphic) at the locus. Information is distributed by(More)
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.

A website (http://www.mcgill.ca/pahdb ) is maintained by the curators for a Consortium (88 investigators, 28 countries) and all other users; it serves a relational database for human locus-specific genetic variation in a defined DNA sequence (GenBank U49897); (100 kb on human chromosome 12q24.1, gene symbol PAH). The intragenic nucleotide variation is both(More)
