[[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, both the female (XX) and male (XY) versions of the two [[sex chromosome]]s, as well as the [[human mitochondrial genetics|mitochondrial genome]] (at bottom left). {{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 ''rob'' for Robertsonian translocations.<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|accessdate=2022-10-27}}</ref> For example, rob(21;21)(q10;q10) causes [[Down syndrome]].<ref name="Rajasekhar Rekharao Shetty Gopinath 2010 pp. 49–55">{{cite journal | last1=Rajasekhar | first1=M. | last2=Rekharao | first2=R.
