WDR89 and Usher syndrome: Structural and functional data for three examples of the 17 genes are shown: the DEAD-box helicase 56 (Ddx56), an ATP-dependent RNA helicase; Myo7a, a motor protein associated with Usher syndrome type 1B in humans (Weil et al., 1995); and the WD repeat domain 89 gene (Wdr89), a microtubule-associated protein involved in brain development and autophagy (Kannan et al., 2017) (Figures 7H–7J; Table S2).
