What is the official name of the GTF2IRD1 gene?
The official name of this gene is “GTF2I repeat domain containing 1.”
GTF2IRD1 is the gene's official symbol. The GTF2IRD1 gene is also known by other names, listed below.
What is the normal function of the GTF2IRD1 gene?
The GTF2IRD1 gene provides instructions for making a protein that regulates the activity of many other genes. This protein probably interacts with specific regions of DNA and with other proteins to turn genes on or off. Based on this role, the GTF2IRD1 protein is called a transcription factor.
Although its exact function is unknown, the GTF2IRD1 gene is active in many of the body's tissues. It appears to be particularly important for gene regulation in the brain and in muscles used for movement (skeletal muscles). Studies suggest that this gene also plays a role in the development of tissues in the bones and face (craniofacial development).
How are changes in the GTF2IRD1 gene related to health conditions?
- Williams syndrome - associated with the GTF2IRD1 gene
The GTF2IRD1 gene is located in a region of chromosome 7 that is deleted in people with Williams syndrome. As a result of this deletion, people with this condition are missing one copy of the GTF2IRD1 gene in each cell. Studies suggest that the loss of this gene may contribute to some of the characteristic features of Williams syndrome, including the distinctive facial features, dental abnormalities, and problems with visual-spatial tasks such as writing and drawing. Researchers are investigating how a deletion of this gene may be related to these specific features.
Where is the GTF2IRD1 gene located?
Cytogenetic Location: 7q11.23
Molecular Location on chromosome 7: base pairs 73,868,119 to 74,016,930
The GTF2IRD1 gene is located on the long (q) arm of chromosome 7 at position 11.23.
More precisely, the GTF2IRD1 gene is located from base pair 73,868,119 to base pair 74,016,930 on chromosome 7.
