The International System for Human Cytogenomic Nomenclature (previously International System for Human Cytogenetic Nomenclature), ISCN in short, is an international standard for
human chromosomenomenclature, which includes band names, symbols and abbreviated terms used in the description of human chromosome and
chromosome abnormalities.
The ISCN has been used as the central reference among
cytogeneticists since 1960.[1][2]
Abbreviations of this system include a minus sign (-) for chromosome deletions, and del for deletions of parts of a chromosome.[4]
