What is the official name of the SOX2 gene?
The official name of this gene is “SRY (sex determining region Y)-box 2.”
SOX2 is the gene's official symbol. The SOX2 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 SOX2 gene?
The SOX2 gene provides instructions for making a protein that plays a critical role in the formation of many different tissues and organs during embryonic development. The SOX2 protein is especially important for the development of the eyes. This protein regulates the activity of other genes by attaching (binding) to specific regions of DNA. On the basis of this action, the SOX2 protein is called a transcription factor.
Does the SOX2 gene share characteristics with other genes?
The SOX2 gene belongs to a family of genes called SOX (SRY (sex determining region Y)-box 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.
How are changes in the SOX2 gene related to health conditions?
Genetics Home Reference provides information about these additional conditions, which are also associated with changes in the SOX2 gene:
Where is the SOX2 gene located?
Cytogenetic Location: 3q26.3-q27
Molecular Location on chromosome 3: base pairs 181,429,711 to 181,432,223
The SOX2 gene is located on the long (q) arm of chromosome 3 between positions 26.3 and 27.
More precisely, the SOX2 gene is located from base pair 181,429,711 to base pair 181,432,223 on chromosome 3.
