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…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…A new SPG4/SPAST mutation in an Italian family with hereditary spastic paraplegia and Alzheimer’s disease
Objective: To perform a clinical and a genetic study in an Italian family with a complicated form of hereditary spastic paraplegia (HSP) and Alzheimer’s disease…A new distinct spastic ataxia with hypomyelination: Clinical, neuroimaging and molecular expression of NKX6-2 mutations
Objective: To identify the phenotypic, neuroimaging and genotype-phenotype expression of NKX6-2 mutations. Background: Despite advances in genetic testing a large number of hyopomyelinating disorders remain…Compound-heterozygous mutations in VPS13D are a novel cause of spastic ataxia and lead to mitochondrial dysfunction
Objective: To identify the genetic cause in two sisters with spastic ataxia and to functionally characterize mitochondrial function in patient-derived cells. Background: Spastic ataxia is…Clinical and genetic heterogeneity in portuguese patients with Hereditary Spastic Paraplegia
Objective: To characterize the demographic, clinical and genetic features of HSP and to define the phenotypic spectrum and genotype-specific differences. Background: Hereditary spastic paraplegia (HSP)…A novel homozygous splice site mutation in the KIF1C gene (SPAX2, SPG58) found in a consanguineous turkish family
Objective: We present clinical, electrophysiological and genomic data of a consanguineous family with two affected siblings suffering from spasticity and severe ataxia. Background: Mutations in…
