Natural History of Movement Abnormalities on Hereditary Spastic Paraplegia: validation of timed functional instruments
Objective: To evaluate the natural history of Hereditary Spastic Paraplegia (HSPs) and to define sensitivity to change, minimal clinically important difference (MCID) and validity of…Adaptor Protein Complex 4-associated Hereditary Spastic Paraplegia (AP-4-HSP): A Paradigm of Childhood-Onset Hereditary Spastic Paraplegia Caused By Defective Protein Trafficking
Objective: Aims of this study include: 1) to generate induced pluripotent stem cell (iPSC)-derived neurons from patients with AP-4-associated HSP; 2) to characterize these neurons…The Clinical, Molecular and Radiographic Spectrum of Adaptor Protein Complex 4-associated Hereditary Spastic Paraplegia (AP-4-HSP): Results from the AP-4-HSP International Registry
Objective: 1) To develop a registry and natural history study for AP-4-HSP; 2) to define core clinical and radiographic features; 3) to explore genotype-phenotype correlations.…Symptomatic treatment of hereditary spastic paraplegias with fampridine: a pilot study
Objective: Study the effect of fampridine in gait outcomes in patients with hereditary spastic paraplegia (HSP). Background: Fampridine acts through blockade of voltage-gated potassium channels,…Spastic ataxia and pseudo eye-of-the-tiger sign in a familiy with a novel compound heterozygous AFG3L2 mutations
Objective: Identify by exome sequencing (ES) the underlying etiology of spastic ataxia and pseudo eye-of-the-tiger sign (EOT) in 4 siblings. Background: The EOT is a…Spastic Paraplegia Type 64: a Case Series
Objective: to present four cases (two families) with a likely diagnosis of spastic paraplegia type 64 (SPG 64), broadening this disease phenotype. Background: SPG64 is…A novel p.Trp42Arg REEP1 mutation associated with autosomal recessive Distal spinal muscular atrophy with vocal cord and diaphragmatic paralysis
Objective: To present a patient with homozygous mutation in Receptor Expression-Enhancing Protein 1 (REEP1) gene manifesting a severe congenital Distal spinal muscular atrophy (SMA) with…The Genetic Basis of paediatric movement disorders: experience from the SYNaPS Study
Objective: To identify genetic causes of paediatric movement disorders in a large multi-ethnic cohort of patients by genetic investigations. Background: Pediatric movement disorders which are…Novel p.Pro193Arg missense mutation in ABCD1-gene associated with phenotype of ALD/AMN: a case report
Objective: To describe a novel mutation p.Pro193Arg of the ABCD1-Gene in a patient presenting with clinical phenotype of Adrenomyeloneuropathy (AMN). Background: Adrenoleukodystrophy comprises progressive neurologic…Hereditary spastic paraplegia presenting as limb dystonia with a novel SPG7 mutation
Objective: We present a case of a patient who presented with limb dystonia and was found to have HSP associated with a previously unreported compound…
