Phenotypic analysis of subjects with homozygous and compound heterozygous PANK2 mutations in a single extended pedigree from the Dominican Republic (DR) PKAN cohort
Objective: Whole exome sequencing and genotypic screening of homozygous and heterozygous PANK2 mutations in the Dominican Republic. Background: PKAN affects 1 in 1,000,000 people worldwide,…Comprehensive Screening of Genetic, Genomic, Mitochondrial, and Microbiome Associations with Phenotypic Measures in the Dominican Republic PKAN Cohort
Objective: Establish novel molecular predictors of phenotypic variation using screening of genomic, transcriptomic, mitochondrial, microbiome, and clinical features. Background: Pantothenate Kinase Associated Neurodegeneration (PKAN), also…Dystonic opisthotonus: A clinical clue to neurodegeneration with brain iron accumulation in young adults
Objective: To describe the diagnostic value of dystonic opisthotonus as a clinical clue towards a diagnosis of neurodegeneration with brain iron accumulation. Background: Differential diagnosis…Deep Brain Stimulation (DBS) in Pantothenate Kinase-Associated Neurodegeneration (PKAN): An Experience in a Thai Patient
Objective: To report a patient with PKAN whose dystonia improved with bilateral pallidal (GPi) DBS. Background: The benefits of GPi DBS are well-recognized in primary…Pantothenate kinase-associated neurodegeneration in Tunisian families
Objective: To describe clinical features, imaging and genetic findings of 6 Tunisian families diagnosed with PKAN. Background: Pantothenate kinase-associated neurodegeneration (PKAN) is an autosomal recessive…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…A Systems Approach Model for Pantothenate Kinase-Associated Neurodegeneration (PKAN)- Assessment and Treatment
Objective: Propose a new systems approach model for PKAN, investigate treatment, and establish biologic and genetic markers. Background: PKAN is a recessive, rare, inborn error…Distinct phenotypic expression in a large PKAN cohort in the Dominican Republic
Objective: Analysis of a large genetically homogenous PKAN population, assessing demographics, clinical features, and rating scales to characterize observed phenotypic heterogeneity. Background: PKAN is an…Temporal Emergence of Symptoms and Functional Impairments in Patients With Pantothenate Kinase-Associated Neurodegeneration (PKAN)
Objective: To describe the temporal emergence of PKAN symptoms and functional impairments across the spectrum of PKAN severity. Background: PKAN, an autosomal recessive, progressive neurodegenerative…Associations of Genetic, Epigenetic and Phenotypic Measures in the Dominican Republic PKAN Cohort
Objective: To explore relationships between demographic, clinical and behavioral phenotypes and underlying genetic and epigenetic features, utilizing a large cohort of PKAN patients. Background: PKAN…
