Regarding the latter enriched GO terms, the differential expression of Ush1c and Myo7a genes coding for Usher proteins in the neuroretina of Gnat1rd17 mice is particularly interesting because of their location and function in the connecting cilium and synaptic region of photoreceptors and the association of their mutations with RP [10,103]. This evidence concerns the gene MYO7A and retinitis pigmentosa 1.
