For example, the presence of KIF11 in the connecting cilium of photoreceptors, and the identification of KIF11 mutations in patients with retinal diseases such as MLCRD (microcephaly, lymphedema, and chorioretinal dysplasia), CDMMR (chorioretinal dysplasia, microcephaly, and mental retardation), and FEVR (familial exudative vitreoretinopathy) suggest that KIF11 may play a vital role in the pathological processes of these conditions by mediating photoreceptor ciliary homeostasis [79, 92, 93]. The gene discussed is KIF11; the disease is microcephaly with or without chorioretinopathy, lymphedema, or intellectual disability.
