What is the official name of the TGFBI gene?
The official name of this gene is “transforming growth factor beta induced.”
TGFBI is the gene's official symbol. The TGFBI gene is also known by other names, listed below.

What is the normal function of the TGFBI gene?
The TGFBI gene provides instructions for making a protein called transforming growth factor beta induced (TGFBI). This protein is released (secreted) from cells and becomes part of the extracellular matrix, which is an intricate network that forms in the spaces between cells and provides structural support to tissues. The TGFBI protein is thought to play a role in the attachment of cells to one another (cell adhesion) and cell movement (migration). This protein is found in many tissues in the body, including the the clear, outer covering of the eye (the cornea).
How are changes in the TGFBI gene related to health conditions?
Where is the TGFBI gene located?
Cytogenetic Location: 5q31
Molecular Location on chromosome 5: base pairs 136,028,895 to 136,063,818
(Homo sapiens Annotation Release 107, GRCh38.p2) (
The TGFBI gene is located on the long (q) arm of chromosome 5 at position 31.
More precisely, the TGFBI gene is located from base pair 136,028,895 to base pair 136,063,818 on chromosome 5.
