[[File:Human karyotype with bands and sub-bands.png|thumb|300px|Human [[karyotype]] with annotated bands and sub-bands as used for the nomenclature of chromosome abnormalities. It shows dark and white regions as seen on [[G banding]]. Each row is vertically aligned at [[centromere]] level. It shows 22 [[Homologous chromosome|homologous]] [[autosomal]] chromosome pairs as well as both the female (XX) and male (XY) versions of the two [[sex chromosome]]s. {{further|Karyotype}}]]
The [[International System for Human Cytogenomic Nomenclature]] (ISCN) is an international standard for [[human chromosome]] [[nomenclature]], which includes band names, symbols, and abbreviated terms used in the description of human chromosome and chromosome abnormalities. Abbreviations include ''inv'' for inversions.<ref>{{cite web|url=https://www.coriell.org/0/sections/support/global/iscn_help.aspx?PgId=263|title=ISCN Symbols and Abbreviated Terms|website=Coriell Institute for Medical Research|access-date=2022-10-27|archive-date=2022-10-27|archive-url=https://web.archive.org/web/20221027143728/https://www.coriell.org/0/Sections/Support/Global/iscn_help.aspx?PgId=263|url-status=live}}</ref>
