title: Mutation database for the galactose-1-phosphate uridyltransferase (GALT) gene.
abstract: Classical galactosemia is an autosomal recessive disorder caused by mutations in the galactose-1-phosphate uridyltransferase (GALT) gene. Our group developed a disease-specific database containing all of the reported sequence variants in GALT (Available at: http://arup.utah.edu/database/galactosemia/GALT_welcome.php; Last accessed: 13 April 2007). Currently the database contains a total of 229 sequence variants, of which 196 are mutations (including nine novel mutations identified in our laboratory), 31 polymorphisms in both introns and exons, and two variants of unknown or uncertain significance. All sequence variants have been verified for their position within the GALT gene and named following standard nomenclature. Sequence variants are reported with accompanying information on protein effect, classification of mutation vs. polymorphism, mutation type (when applicable) based on how each was first described in the literature, and accompanying link to pertinent publication. Unpublished variants are described with relevant clinical information that supports their classification as causative of the disease vs. polymorphisms. Other features of this database include disease information, relevant links for galactosemia and literature, reference sequences, ability to query by various criteria, and submit of novel variations to the database. This free online scientific resource was developed with the clinical laboratory in mind to serve as a reference and repository for novel findings that are periodically collected, verified, and updated into the database.
