Novel Recessive Mitochondrial Mutations Causing Leigh’s Syndrome and Movement Disorders
Objective: Describe discovery of novel mitochondrial mutations causing ataxia and dystonia syndromes with occurrence in childhood. Background: An African-American man at 5 years old subacutely…Adult onset of Dandy-Walker Syndrome
Objective: To identify what could be causing a full, progressive cerebellar syndrome on a previously healthy 40 year old woman. Background: A 40-year old woman…Reclassification of variant c.5825C>T and clinical evidence of variant c.3955_3958dup in a Peruvian family with ATM syndrome
Objective: To describe a Peruvian family carrying variants c.3955_3958dup and c.5825C>T in the ATM gene. Background: Pathogenic variants at ATM gene are associated both, to…Clinical and genetic abnormalities in patients with Friedreich’s ataxia: A genotype-phenotype correlation
Objective: To examine the possibility of molecular finding affecting FRDA phenotype, we studied the clinical features and ascertained the GAA repeat sizes in FRDA patients…New pathogenic mutation in the Niemann-Pick C (NPC) Type 1 gene: Confirmation by diagnostic workup of NPC in a 41-year-old woman with idiopathic late onset cerebellar ataxia (ILOCA)
Objective: We present an instructive case of a 41-year-old woman with idiopathic late onset cerebellar ataxia. Background: Identifying the cause of idiopathic late onset cerebellar…Clinical correlation with the Genotype of Friedreich’s Ataxia (FRDA) patients in Indian population
Objective: To describe genotype-phenotype correlation in Indian FRDA patients. Background: Friedreich’s Ataxia(FRDA), an early onset rare autosomal recessive ataxia is caused by bi-allelic loss of…Association of TTPA mutation and peripheral nerve involvement in Gait disturbances in Ataxia With Vitamin E Deficiency (AVED)
Objective: To determine if peripheral nerve involvement and the type of TTPA mutation are determinant for gait ataxia in patients with AVED in vitamin E…Gerstmann-Sträussler-Scheinker disease presenting as a late onset slowly progressive spinocerebellar ataxia: expanding the phenotypic spectrum of genetic prion disease
Objective: We describe a late-onset presentation of Gerstmann-Sträussler-Scheinker disease (GSS) with a novel mutation in the prion protein (PRNP) gene. We compare this case to…Upward Gaze Palsy in SCA3: a valuable semiological sign
Objective: Evaluate the prevalence of upward gaze palsy (UGP) and investigate its useful in assisting the clinical differentiation of SCAs. Background: Spinocerebellar ataxias (SCAs) represent…Clinical and imagiological features in Portuguese patients with SPG7 mutations
Objective: To better characterize spastic paraplegia type 7 (SPG7) phenotype in a Portuguese cohort of patients. Background: Hereditary spastic paraplegias(HSP) and cerebellar ataxias(CA) are heterogeneous…
