ABSTRACT

Alport Syndrome is a progressive renal disease with cochlear and ocular involvement. The most common form ( approximately 80%) is inherited in an X-linked pattern. X-linked Alport Syndrome (XLAS) is caused by mutations in the type IV collagen alpha chain 5 (COL4A5). We have developed a curated disease-specific database containing reported sequence variants in COL4A5. Currently the database archives a total of 520 sequence variants, verified for their position within the COL4A5 gene and named following standard nomenclature. Sequence variants are reported with accompanying information on protein effect, classification of mutation vs. polymorphism, mutation type based on the first description in the literature, and links to pertinent publications. In addition, features of this database include disease information, relevant links for Alport syndrome literature, reference sequence information, and ability to query by various criteria. On-line submission for novel gene variants or updating information on existing database entries is also possible. This free online scientific resource was developed with the clinical laboratory in mind to serve as a reference and repository for COL4A5 variants.

ABSTRACT

Multiple endocrine neoplasia type 2 (MEN2) is an inherited, autosomal-dominant disorder caused by deleterious mutations within the RET protooncogene. MEN2 RET mutations are mainly heterozygous, missense sequence changes found in RET exons 10, 11, and 13-16. Our group has developed the publicly available, searchable MEN2 RET database to aid in genotype/phenotype correlations, using Human Genome Variation Society recommendations for sequence variation nomenclature and database content. The MEN2 RET database catalogs all RET sequence variation relevant to the MEN2 syndromes, with associated clinical information. Each database entry lists a RET sequence variation's location within the RET gene, genotype, pathogenicity classification, MEN2 phenotype, first literature reference, and comments (which may contain information on other clinical features, complex genotypes, and additional literature references). The MEN2 phenotype definitions were derived from the International RET Mutation Consortium guidelines for classification of MEN2 disease phenotypes. Although nearly all of the 132 RET sequence variation entries initially cataloged in the database were from literature reports, novel sequence variation and updated phenotypic information for any existing database entry can be submitted electronically on the database website. The database website also contains links to selected MEN2 literature reviews, gene and protein information, and RET reference sequences. The MEN2 RET database (www.arup.utah.edu/database/MEN2/MEN2_welcome.php) will serve as a repository for MEN2-associated RET sequence variation and reference for RET genotype/MEN2 phenotype correlations.
