What is the official name of the MSX1 gene?
The official name of this gene is “msh homeobox 1.”
MSX1 is the gene's official symbol. The MSX1 gene is also known by other names, listed below.
Read more about gene names and symbols on the About page.
What is the normal function of the MSX1 gene?
The MSX1 gene provides instructions for making a protein that regulates the activity of other genes. The MSX1 gene is part of a larger family of homeobox genes, which act during early development to control the formation of many body structures. Specifically, this gene is critical for the normal development of the teeth and other structures in the mouth. It may also be important for development of the fingernails and toenails.
Does the MSX1 gene share characteristics with other genes?
The MSX1 gene belongs to a family of genes called homeobox (homeoboxes).
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.
