“…Two studies did not mention the diagnostic criteria for HLD (Fedotova et al, 2016;Kaur et al, 2020). At least six studies described a diagnostic workup that excluded other genetic causes of HLD including neuroacanthocytosis, neurodegeneration with brain iron accumulation, DJ-1 mutations, cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy disease, HLD type 2, SCA-1, SCA-2, SCA-3, SCA-7, SCA-8, SCA-12, SCA-10, SCA-17, dentatorubral-pallidoluysian atrophy, and familial prion disease (Kostic et al, 2014;Koutsis et al, 2015;Mariani et al, 2016;Baine et al, 2018;Martins et al, 2018a;Rikos et al, 2020).…”
