DOCK3 and cerebellar ataxia: Other genes are related to cytoskeleton remodeling, including Cdh4, Pcdh9, Dock5, Dock3 for the proprioceptors (mutation of Dock3 is known to results in ataxia) and Stom and Pdlim1 for mechanoreceptors, as well as ion channels (Asic1 and Kcnip2 for proprioceptive fate).
