{{Short description|Mammalian protein found in Homo sapiens}} {{Redirect|SHOX}} {{Infobox gene}} The '''short-stature homeobox gene''' ('''SHOX'''), also known as '''short-stature-homeobox-containing gene''', is a gene located on both the X and Y chromosomes, which is associated with short stature in humans if mutated or present in only one copy (haploinsufficiency).

==Pathology== SHOX was first found during a search for the cause of short stature in women with Turner syndrome, where there is loss of genetic material from the X chromosome, typically by loss of one entire X chromosome.<ref name="NIHSHOX">{{cite web | url = http://ghr.nlm.nih.gov/gene=shox | title = SHOX - short stature homeobox - Genetics Home Reference | access-date = 2008-02-18 | date = 2005-09-01 | publisher = U.S. National Library of Medicine | archive-date = 2007-10-12 | archive-url = https://web.archive.org/web/20071012215043/http://ghr.nlm.nih.gov/gene=shox | url-status = dead }}</ref>

Since its discovery, the gene has been found to play a role in idiopathic short stature, Léri-Weill dyschondrosteosis, and Langer mesomelic dysplasia.

Gene dosage effects of extra copies of SHOX may be a cause of the increased stature seen in other sex chromosome aneuploidy conditions such as triple X, XYY, Klinefelter, XXYY and similar syndromes.<ref name="pmid14752208">{{cite journal | vauthors = Kanaka-Gantenbein C, Kitsiou S, Mavrou A, Stamoyannou L, Kolialexi A, Kekou K, Liakopoulou M, Chrousos G | display-authors = 6 | title = Tall stature, insulin resistance, and disturbed behavior in a girl with the triple X syndrome harboring three SHOX genes: offspring of a father with mosaic Klinefelter syndrome but with two maternal X chromosomes | journal = Hormone Research | volume = 61 | issue = 5 | pages = 205–10 | year = 2004 | pmid = 14752208 | doi = 10.1159/000076532 | s2cid = 41958098 }}</ref>

==Genetics and function==

SHOX is composed of 6 different exons and is located in the pseudoautosomal region 1 (PAR1) of the X chromosome (Xp22.33) and Y chromosome.<ref name="NIHSHOX"/> Since genes in PAR escape X inactivation, their dosage changes with sex chromosome aneuploidies such as Turner.<ref>{{cite journal | vauthors = Raudsepp T, Chowdhary BP | title = The Eutherian Pseudoautosomal Region | language = english | journal = Cytogenetic and Genome Research | volume = 147 | issue = 2–3 | pages = 81–94 | date = 2015 | pmid = 26730606 | doi = 10.1159/000443157 | url = https://www.karger.com/Article/FullText/443157 | doi-access = free | hdl = 10576/22940 | hdl-access = free }}</ref>

Similar genes are present in a variety of animals and insects.

It is a homeobox gene, meaning that it helps to regulate development.
