Short stature homeobox gene
or SHOX is a gene on the X chromosome and Y chromosome which is associated with short stature in humans if mutated or present in only one copy.The gene was first found during a search for the cause of short stature in women with Turner syndrome, in which there is loss of genetic material from the X chromosome, classically by loss of one entire X chromosome.SHOX gene has been found to play a role in idiopathic short stature, Léri-Weill dyschondrosteosis, and Langer mesomelic dysplasia. The SHOX gene is a homeobox gene, meaning that it helps regulate development. The SHOX gene is composed of 6 different exons and is located in the pseudoautosomal region (PAR1) of the X chromosome and Y chromosome. Experiments have found similar genes in a variety of animals and insects.
