The dysmorphic human-mouse homology database (DHMHD): an interactive World-Wide Web resource for gene mapping

Genetic mapping and the examination of "candidate genes" for isolating loci associated with clinical syndromes can be greatly accelerated if there is information about where in the genome a particular locus might be situated. Such clues can come from homology to mouse mutants that have been mapped and knowledge of homology between mouse and human chromosomal segments. Further clues can come from chromosome aberrations giving a similar phenotype. However, these clues are often scattered widely in published reports, and even if they are collected together in catalogues or databases there is no rapid way of moving from one data type to another. The Dysmorphic Human and Mouse Homology Database (DHMHD) is designed to ease this data transition. DHMHD comprises detailed information from four separate sources and enables cross referencing through phenotypic and chromosome homology. The DHMHD system is a prototype which is now available online through the World-Wide Web.
