MAPT and frontotemporal dementia: Other top‐weighted variants near NSF and ATXN3 indicate potential biological plausibility: rs10143310 is found near ATXN3 which encodes a de‐ubiquitinating enzyme, and polyglutamine expansions in ATXN3 cause spinocerebellar ataxia—type 3 (Burnett et al, 2003); rs7224296 near NSF tags the MAPT H1 haplotype (Yokoyama et al, 2017) and is associated with increased risk for FTD syndromes including progressive supranuclear palsy and corticobasal degeneration (Ferrari et al, 2017), as well as Alzheimer’s and Parkinson’s diseases (Desikan et al, 2015).
