With the forthcoming identification of the gene targets that trigger Purkinje cell death in the robotic cerebellum, and the functional conservation among the ALF proteins, the robotic mouse promises to deliver important insights into the pathogenesis of human ataxia, but also of mental retardation to which FMR2 and LAF4 have been linked.
This FMR2-related gene family encodes nuclear proteins with involvement in mental retardation (FMR2), cancer (AF4), and lymphocyte differentiation (LAF4) or with unknown function (EST W26686 and/or AA025630).
