What is the official name of the OFD1 gene?
The official name of this gene is “oral-facial-digital syndrome 1.”
OFD1 is the gene's official symbol. The OFD1 gene is also known by other names, listed below.

What is the normal function of the OFD1 gene?
The OFD1 gene provides instructions for making a protein whose function is not fully understood. It appears to play a critical role in the early development of many parts of the body, including the brain, face, limbs, and kidneys.
The OFD1 protein is located at the base of cilia, which are finger-like projections that stick out from the surface of cells. Cilia are involved in cell movement and in many different chemical signaling pathways. They play important roles in the development and function of many parts of the body. Researchers suspect that the OFD1 protein is essential for the normal formation of cilia.
Studies suggest that the OFD1 protein may have additional functions. In the earliest stages of development, it appears to be involved in determining the left-right axis (the imaginary line that separates the left and right sides of the body). The OFD1 protein is also found in the nucleus, although its function in this cell structure is unknown.
How are changes in the OFD1 gene related to health conditions?
Genetics Home Reference provides information about these additional conditions, which are also associated with changes in the OFD1 gene:
Where is the OFD1 gene located?
Cytogenetic Location: Xp22
Molecular Location on the X chromosome: base pairs 13,715,429 to 13,769,360
The OFD1 gene is located on the short (p) arm of the X chromosome at position 22.
More precisely, the OFD1 gene is located from base pair 13,715,429 to base pair 13,769,360 on the X chromosome.
