Neuronal disorders, like Huntington's disease (HD), are difficult to study, due to limited cell accessibility, late onset manifestations, and low availability of material. The establishment of an in vitro model that recapitulates features of the disease may help understanding the cellular and molecular events that trigger disease manifestations. Here, we(More)
BACKGROUND Autosomal dominant cerebellar ataxias are a clinical and genetically heterogeneous group of progressive neurodegenerative diseases, at present associated with 22 loci (spinocerebellar ataxia [SCA] 1-SCA8, SCA10-SCA19, SCA21, SCA22, fibroblast growth factor 14 [FGF14]-SCA, and dentatorubral-pallidoluysian atrophy [DRPLA]). The relevant gene has(More)
SCA6 is caused by CAG expansion in the alpha 1A voltage-dependent calcium channel subunit gene. The authors studied an Italian family in which one patient carried a fully expanded SCA6 allele with 26-CAG repeats, whereas the other affected family member was homozygous for an intermediate-size allele of 19-CAG repeats. Three family members, heterozygous for(More)
SCA17 is a rare type of autosomal dominant spinocerebellar ataxia caused by a CAG/CAA expansion in the gene encoding the TATA-binding protein (TBP). We screened for triplet expansion in the TBP gene 110 subjects with progressive cerebellar ataxia and 94 subjects with Huntington-like phenotype negative at specific molecular tests. SCA17 mutation-positive(More)
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease mainly involving cortical and spinal motor neurons. Several studies indicated that intermediate CAG expansions in ataxin-2 gene (ATXN2) are associated with increased risk of ALS. We analyzed ATXN2 CAG repeats in 658 sporadic ALS patients (SALS), 143 familial ALS cases (FALS), 231 sporadic(More)
Mutations in valosin-containing protein (VCP) gene, already known to be associated with the multisystemic disorder, inclusion body myopathy with Paget's disease and frontotemporal dementia (IBMPFD), have been recently found also in familial cases of amyotrophic lateral sclerosis (ALS). To further define the frequency of VCP mutations in ALS Italian(More)
