title: The dbMHC microsatellite portal: a public resource for the storage and display of MHC microsatellite information.
abstract: Major histocompatibility complex (MHC) region Microsatellites (Msat) have been extensively used in various applications, such as disease mapping, forensics, and population genetics. A comprehensive review of HLA Msat primers has been previously published based on literature and sequence analysis, but electronic tools are lacking to make it easily accessible and actually used by the community. We have integrated data from this review, with an overlapping set of 31 Msat markers used in the 13th International Histocompatibility and Immunogenetics Workshop (IHIWS) to create a public archive that will synchronize published descriptions to a common framework. http://www.ncbi.nlm.nih.gov/projects/mhc. Currently, the dbMHC contains 389 primer pairs across the extended MHC targeting 281 distinct repeat regions (approximately 1/45 kb). Literature review and analysis of the primers reveal that over 200 synonymous names have been published for these markers. Users may view or download specific Msat data sets using the portal. Query options include name or partial name, primer sequence, neighboring genes, and/or position. Query results include locus name(s), a graphic showing of the relative location of the marker in relation to the classical HLA genes, a listing of the constituent primer pairs and name, a link to UniSTS, aliases, allele range (bp), overlapping single nucleotide polymorphisms, a link to e-polymerase chain reaction, and physical mapping information. To increase the utility of this resource, researchers using Msat markers in the HLA region are encouraged by the authors to submit new primers to the dbMHC. The minimal Msat submission consists of primers sequences, a submitter's name and contact information. Additional information recommended but not required is the laboratory protocol(s), known allele size range (bp), known aliases, and an exemplar sequence. Assigned UniSTS numbers can be used for primer pair standard identification.
