At the First International Equine Gene Mapping Workshop in Lexington, Kentucky (1995), the need was recognized for a horse idiogram defining regions, bands and sub-bands for the precise identification of individual chromosomes, both G- and R-banded. A consensus standard is essential 1) for use in the developing physical and genetic linkage maps using FISH techniques, 2) for defining precisely the physical boundaries of correspondence between genomes of different taxa, and 3) for defining numerical abnormalities and the precise breakpoint location of chromosomal aberrations. The nine-member committee has completed and published its report: International System for Cytogenetic Nomenclature of the Domestic Horse (ISCNH). Copies will be available.
