Neurology
The goal of genetic testing for hereditary neurological diseases is to determine whether or not a patient has the disease, or is likely to develop it. Determining the molecular cause of a neurological disease can open the door to individually tailored treatment and medical care, and allow families to avoid invasive and often costly testing and procedures.

17q23.2q23.3 de Novo Duplication
Chromosomal rearrangements involving 17q23 have been described rarely. Deletions at 17q23.1q23.2 have been reported in individuals with developmental delay and growth retardation, whereas duplications at 17q23.1q23.2 appear to segregate with clubfoot. We report a 7.5-year-old boy with speech and…

Functional Characterization of Rare RAB12 Variants
Mutations in RAB (member of the Ras superfamily) genes are increasingly recognized as cause of a variety of disorders including neurological conditions. While musician's dystonia (MD) and writer's dystonia (WD) are task-specific movement disorders, other dystonias persistently affect postures as in…

Clinical and Genetic Characteristics of Sporadic Adult-Onset Degenerative Ataxia
The objective of this study is to define the clinical phenotype and natural history of sporadic adult-onset degenerative ataxia and to identify putative disease-causing mutations. The primary measure of disease severity was the Scale for the Assessment and Rating of Ataxia (SARA). DNA samples were…

Heart and Nervous System Pathology in Compound Heterozygous Friedreich Ataxia
In a small percentage of patients with Friedreich ataxia (FA), the pathogenic mutation is compound heterozygous, consisting of a guanine–adenine–adenine (GAA) trinucleotide repeat expansion in one allele, and a deletion, point mutation, or insertion in the other. In 2 cases of compound heterozygous…

BioMannosidosis – Biomarker for Alpha-Mannosidosis Disease
Alpha-mannosidosis is a rare lysosomal storage disorder of the Glycoprotein family of diseases and is closely related to Mucopolysaccharidoses. The goal of this study is to identify and validate a new biochemical marker from the plasma of affected patients helping to benefit other patients by an…
