"But recently, Adem Yildirim in his PhD thesis conducted in the International PhD Program (IPP) in Mainz discovered that SANS interacts with splicing factors to regulate pre-mRNA splicing.". The location and function of the other two proteins are not yet known. Suddenly they were chatty. Usher syndrome is characterized by deafness due to an impaired ability of the inner ear and auditory nerves to transmit sensory (sound) input to the brain (sensorineural hearing loss) as well as abnormal accumulation of colored (pigmented) material on the nerve-rich membrane (the retina) lining the eyes (retinitis pigmentosa or RP). Several genes have been associated with Usher syndrome using linkage analysis of patient families (Table 1) and DNA sequencing of the identified loci.
