What is the normal function of the BBS1 gene?
The BBS1 gene provides instructions for making a protein found in cells throughout the body. The BBS1 protein is part of a group (complex) of proteins that plays a critical role in the formation of cell structures called cilia. Cilia are microscopic, finger-like projections that stick out from the surface of many types of cells. They are involved in cell movement and many different chemical signaling pathways. Cilia are also necessary for the perception of sensory input (such as sight, hearing, and smell).
How are changes in the BBS1 gene related to health conditions?
Where is the BBS1 gene located?
Cytogenetic Location: 11q13

The BBS1 gene is located on the long (q) arm of chromosome 11 at position 13.
More precisely, the BBS1 gene is located from base pair 66,510,648 to base pair 66,533,613 on chromosome 11.
