These findings overlapped with several studies reporting atrophy in the PT in SCA3 and/or SCA6 (Schulz et al., 2010; D’Abreu et al., 2012, Reetz et al., 2013; De Rezende et al., 2015); however, those studies also found atrophy in the CN, which was not observed here. This evidence concerns the gene ATXN3 and Atrophy.
