What is the official name of the SHOX gene?
The official name of this gene is “short stature homeobox.”
SHOX is the gene's official symbol. The SHOX gene is also known by other names, listed below.

What is the normal function of the SHOX gene?
The SHOX gene provides instructions for making a protein that regulates the activity of other genes. On the basis of this role, the SHOX protein is called a transcription factor. The SHOX gene is part of a large family of homeobox genes, which act during early embryonic development to control the formation of many body structures. Specifically, the SHOX gene is essential for the development of the skeleton. It plays a particularly important role in the growth and maturation of bones in the arms and legs.
One copy of the SHOX gene is located on each of the sex chromosomes (the X and Y chromosomes) in an area called the pseudoautosomal region. Although many genes are unique to either the X or Y chromosome, genes in the pseudoautosomal region are present on both chromosomes. As a result, both females (who have two X chromosomes) and males (who have one X and one Y chromosome) have two functional copies of the SHOX gene in each cell.
Does the SHOX gene share characteristics with other genes?
A gene family is a group of genes that share important characteristics. Classifying individual genes into families helps researchers describe how genes are related to each other. For more information, see What are gene families? in the Handbook.

Where is the SHOX gene located?
Cytogenetic Location: Xp22.33;Yp11.3
Molecular Location on the X chromosome and the Y chromosome: base pairs 535,078 to 570,145
More precisely, the SHOX gene is located from base pair 535,078 to base pair 570,145 on the X chromosome and the Y chromosome.
