SOX gene family

Reviewed March 2009

What are the SOX genes?

Genes in the SOX family play a critical role in the formation of tissues and organs during early development. These genes also maintain the normal function of certain cells after birth. To carry out these roles, genes in the SOX family provide instructions for making proteins that attach (bind) to specific areas of DNA. By attaching to regions of DNA near genes, SOX proteins help control the activity of those genes. SOX proteins are called transcription factors on the basis of this action.

Researchers have identified 20 genes in the SOX family. Mutations in these genes lead to disorders that involve the abnormal development of tissues in which a particular SOX gene is active (expressed). As a result, the genetic disorders caused by SOX mutations typically have a wide variety of signs and symptoms.

Which genes are included in the SOX gene family?

The HUGO Gene Nomenclature Committee (HGNC) provides an index of gene familiesThis link leads to a site outside Genetics Home Reference. and their member genes.

Genetics Home Reference summarizes the normal function and health implications of these members of the SOX gene family: SOX2, SOX9, and SOX10.
