What is the official name of the T gene?
The official name of this gene is “T brachyury transcription factor.”
T is the gene's official symbol. The T 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 T gene?
The T gene provides instructions for making a protein called brachyury. Brachyury is a member of a protein family called T-box proteins, which play critical roles during embryonic development. T-box proteins regulate the activity of other genes by attaching (binding) to specific regions of DNA. On the basis of this action, T-box proteins are called transcription factors.
The brachyury protein is important for the development of the notochord, which is the precursor of the spinal column in the embryo. The notochord disappears before birth, but in a small percentage of individuals, some of its cells remain in the base of the skull or in the spine. The notochord helps control the development of the neural tube, which is a layer of cells that ultimately develops into the brain and spinal cord.
Does the T gene share characteristics with other genes?
The T gene belongs to a family of genes called TBX (T-boxes).
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 T gene located?
Cytogenetic Location: 6q27
Molecular Location on chromosome 6: base pairs 166,157,656 to 166,168,669
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The T gene is located on the long (q) arm of chromosome 6 at position 27.
More precisely, the T gene is located from base pair 166,157,656 to base pair 166,168,669 on chromosome 6.
