Rab11 has been implicated in fly models for neurodegenerative disorders including Alzheimer's disease (AD) and Huntington's disease (HD) (Breda et al., 2015; Dumanchin et al., 1999; Greenfield et al., 2002; Li et al., 2012, 2009a,b, 2010; Richards et al., 2011; Steinert et al., 2012). This evidence concerns the gene RAB11A and early-onset autosomal dominant Alzheimer disease.
