What is the normal function of the CLRN1 gene?
The CLRN1 gene provides information for making a protein called clarin 1. This protein is probably involved in normal vision and hearing. Clarin 1 has been found in several tissues in the body, including hair cells, which are sensory cells in the inner ear that help transmit sound and motion signals to the brain. This protein is also active in the light-sensing tissue that lines the back of the eye (the retina). Although the function of clarin 1 has not been determined, studies suggest that it plays role in nerve cell communication in the inner ear and retina. Clarin 1 may be important for the function of synapses, which are junctions between nerve cells where cell-to-cell communication occurs.
