Direct interaction between causative genes of DYT1 and DYT6 primary dystonia.

ABSTRACT: Primary dystonia is a movement disorder characterized by sustained muscle contractions and in which dystonia is the only or predominant clinical feature. TOR1A(DYT1) and the transcription factor THAP1(DYT6) are the only genes identified thus far for primary dystonia. Using electromobility shift assays and chromatin immunoprecipitation (ChIP) quantitative polymerase chain reaction (qPCR), we demonstrate a physical interaction between THAP1 and the TOR1A promoter that is abolished by pathophysiologic mutations. Our findings provide the first evidence that causative genes for primary dystonia intersect in a common pathway and raise the possibility of developing novel therapies targeting this pathway.

DYT6 Dystonia: A Neuropathological Study.

Project description:BackgroundMutations in the thanatos-associated protein domain containing apoptosis-associated protein 1 gene (THAP1) are responsible for adult-onset isolated dystonia (DYT6). However, no neuropathological studies of genetically proven DYT6 cases have been previously reported.ObjectiveWe report the first detailed neuropathological investigation carried out on two DYT6 brains.MethodsGenetic screening for THAP1 gene mutations using standard Sanger polymerase chain reaction sequencing identified 2 cases, 1 with a known pathogenic mutation and the other with a novel mutation. A detailed neuropathological assessment of the cases was performed.ResultsBoth DYT6 cases showed no significant neurodegeneration and no specific disease-related pathology.ConclusionsNo neuropathological features that could be defined as hallmark features of DYT6 dystonia were identified. Our study supports the notion that in isolated dystonia, there is no significant neurodegeneration or morphological lesions that can be identified using routine methods.

The Effect of Globus Pallidus Interna Deep Brain Stimulation on a Dystonia Patient with the GNAL Mutation Compared to Patients with DYT1 and DYT6.

Project description:ObjectiveThe aim of this study was to investigate the efficacy of globus pallidus interna deep brain stimulation (GPi-DBS) for treating dystonia due to the GNAL mutation.MethodsWe provide the first report of a dystonia patient with a genetically confirmed GNAL mutation in the Korean population and reviewed the literature on patients with the GNAL mutation who underwent GPi-DBS. We compared the effectiveness of DBS in patients with the GNAL mutation compared to that in patients with DYT1 and DYT6 in a previous study.ResultsPatients with the GNAL mutation and those with DYT1 had higher early responder rates (GNAL, 5/5, 100%; DYT1, 7/7, 100%) than did patients with DYT6 (p = 0.047). The responder rates at late follow-up did not differ statistically among the three groups (p = 0.278). The decrease in the dystonia motor scale score in the GNAL group was 46.9% at early follow-up and 63.4% at late follow-up.ConclusionGPi-DBS would be an effective treatment option for dystonia patients with the GNAL mutation who are resistant to medication or botulinum toxin treatment.

The Frequency of DYT1 (GAG Deletion) Mutation in Primary Dystonia Patients from Iran.

Project description:OBJECTIVE:To determine the frequency of DYT1 mutation in Iranian patients affected with primary dystonia. MATERIALS AND METHODS:In this study, we investigated 60 patients with primary dystonia who referred to the Tehran Medical Genetics Laboratory (TMGL) to determine the deletional mutation of 904-906 del GAG in the DYT1 gene. DNA extracted from patients' peripheral blood was subjected to PCR-sequencing for exon 5 of the DYT1 gene. The collection of samples was based on random sampling. RESULTS:The deletional mutation of 904-906 del GAG in the DYT1 gene (15099 to 15101 based on reference sequence: NG_008049.1) was identified in 11 patients (18.33%). The average age of affected patients with this mutation was 13.64 ± 7.4 years. CONCLUSION:It can be concluded that the DYT1 deletional mutation of 904-906 del GAG has a high frequency in Iranian patients in comparison with other non-Jewish populations. Therefore, this particular mutation may be the main representative of pathogenic DYT1 gene for a large proportion of Iranian patients with primary dystonia.

Mutations in THAP1/DYT6 reveal that diverse dystonia genes disrupt similar neuronal pathways and functions.

Project description:Dystonia is characterized by involuntary muscle contractions. Its many forms are genetically, phenotypically and etiologically diverse and it is unknown whether their pathogenesis converges on shared pathways. Mutations in THAP1 [THAP (Thanatos-associated protein) domain containing, apoptosis associated protein 1], a ubiquitously expressed transcription factor with DNA binding and protein-interaction domains, cause dystonia, DYT6. There is a unique, neuronal 50-kDa Thap1-like immunoreactive species, and Thap1 levels are auto-regulated on the mRNA level. However, THAP1 downstream targets in neurons, and the mechanism via which it causes dystonia are largely unknown. We used RNA-Seq to assay the in vivo effect of a heterozygote Thap1 C54Y or ?Exon2 allele on the gene transcription signatures in neonatal mouse striatum and cerebellum. Enriched pathways and gene ontology terms include eIF2? Signaling, Mitochondrial Dysfunction, Neuron Projection Development, Axonal Guidance Signaling, and Synaptic LongTerm Depression, which are dysregulated in a genotype and tissue-dependent manner. Electrophysiological and neurite outgrowth assays were consistent with those enrichments, and the plasticity defects were partially corrected by salubrinal. Notably, several of these pathways were recently implicated in other forms of inherited dystonia, including DYT1. We conclude that dysfunction of these pathways may represent a point of convergence in the pathophysiology of several forms of inherited dystonia.

Blood expression profiles define penetrance in DYT1 dystonia patients

Project description:DYT1 dystonia is an autosomal-dominantly inherited movement disorder, which is usually caused by a GAG deletion in the TOR1A gene. Due to the reduced penetrance of ~30-40%, the determination of the mutation in a subject is of limited use with regard to actual manifestation of symptoms. In the present study, we used Affymetrix oligonucleotide microarrays to analyze global gene expression in blood samples of 15 manifesting and 15 non-manifesting mutation carriers in order to identify a susceptibility profile beyond the GAG deletion which is associated with the manifestation of symptoms in DYT1 dystonia.We identified a genetic signature which distinguished between asymptomatic mutation carriers and symptomatic DYT1 patients with 86.7% sensitivity and 100% specificity. This genetic signature could correctly predict the disease state in an independent test set with a sensitivity of 87.5% and a specificity of 85.7%.Conclusively, this genetic signature might provide a possibility to distinguish DYT1 patients from asymptomatic mutation carriers.

Unraveling Molecular Mechanisms of THAP1 Missense Mutations in DYT6 Dystonia.

Project description:Mutations in THAP1 (THAP domain-containing apoptosis-associated protein 1) are responsible for DYT6 dystonia. Until now, more than eighty different mutations in THAP1 gene have been found in patients with primary dystonia, and two third of them are missense mutations. The potential pathogeneses of these missense mutations in human are largely elusive. In the present study, we generated stable transfected human neuronal cell lines expressing wild-type or mutated THAP1 proteins found in DYT6 patients. Transcriptional profiling using microarrays revealed a set of 28 common genes dysregulated in two mutated THAP1 (S21T and F81L) overexpression cell lines suggesting a common mechanism of these mutations. ChIP-seq showed that THAP1 can bind to the promoter of one of these genes, superoxide dismutase 2 (SOD2). Overexpression of THAP1 in SK-N-AS cells resulted in increased SOD2 protein expression, whereas fibroblasts from THAP1 patients have less SOD2 expression, which indicates that SOD2 is a direct target gene of THAP1. In addition, we show that some THAP1 mutations (C54Y and F81L) decrease the protein stability which might also be responsible for altered transcription regulation due to dosage insufficiency. Taking together, the current study showed different potential pathogenic mechanisms of THAP1 mutations which lead to the same consequence of DYT6 dystonia.

The DYT6 Dystonia Protein THAP1 Regulates Myelination within the Oligodendrocyte Lineage.

Project description:The childhood-onset motor disorder DYT6 dystonia is caused by loss-of-function mutations in the transcription factor THAP1, but the neurodevelopmental processes in which THAP1 participates are unknown. We find that THAP1 is essential for the timing of myelination initiation during CNS maturation. Conditional deletion of THAP1 in the CNS retards maturation of the oligodendrocyte (OL) lineage, delaying myelination and causing persistent motor deficits. The CNS myelination defect results from a cell-autonomous requirement for THAP1 in the OL lineage and is recapitulated in developmental assays performed on OL progenitor cells purified from Thap1 null mice. Loss of THAP1 function disrupts a core set of OL maturation genes and reduces the DNA occupancy of YY1, a transcription factor required for OL maturation. These studies establish a role for THAP1 transcriptional regulation at the inception of myelination and implicate abnormal timing of myelination in the pathogenesis of childhood-onset dystonia.
