OBJECTIVES: I. Clinically evaluate members from families with dominantly inherited ataxias and collect blood samples for detailed molecular studies.
II. Perform detailed clinical evaluations on patients with recessively inherited ataxias.
PROTOCOL OUTLINE: Participants undergo a comprehensive clinical and molecular evaluation. Studies include: neurologic evaluation, including magnetic resonance imaging and nerve conduction studies; ophthalmologic exam; audiologic exam, including auditory brain stem evoked response; DNA extraction for lymphoblastoid cell lines; gene mapping; and linkage analysis.
A neuropathologic evaluation is conducted postmortem, when possible. Patients with recessive ataxia also receive a developmental assessment.
Primary Purpose: Screening

The purpose of this research study is to investigate how the brain and motor behavior changes both in individuals with spinocerebellar ataxia and healthy individuals, and to assess whether...
The hereditary cerebellar ataxias include diverse neurodegenerative disorders. Hereditary ataxias can be divided into autosomal dominant ataxias (ADCAs), autosomal recessive ataxias (ARCAs...
This research is being done to find out if Baclofen, a medicine that is often used for the treatment of abnormal stiffness, might also be useful to treat some of the neurologic problems ca...
Friedreich ataxia (FRDA) is a progressive neurodegenerative disease of children and adults for which there is presently no therapy. Recently, a study reported that interferon gamma (IFN-g)...
The purpose of this study is to determine if varenicline is effective in treating symptoms of Friedreich's ataxia.
Increasing availability of next-generation sequencing technologies has revealed several limitations of diagnosis-driven traditional clinicogenetic disease classifications, particularly among patients ...
Spinocerebellar ataxia (SCA) is a neural disorder, which is caused by degenerative changes in the cerebellum. SCA is primarily characterized by gait ataxia, and additional clinical features include ny...
This review aims at updating the clinical and genetic aspects of hereditary spastic paraplegias (HSPs) and hereditary cerebellar ataxias (HCAs), focusing on the concept of spastic-ataxia phenotypic sp...
Impairment of the ability to perform smoothly coordinated voluntary movements. This condition may affect the limbs, trunk, eyes, pharynx, larynx, and other structures. Ataxia may result from impaired sensory or motor function. Sensory ataxia may result from posterior column injury or PERIPHERAL NERVE DISEASES. Motor ataxia may be associated with CEREBELLAR DISEASES; CEREBRAL CORTEX diseases; THALAMIC DISEASES; BASAL GANGLIA DISEASES; injury to the RED NUCLEUS; and other conditions.
Forms of hereditary angioedema that occur due to mutations in the gene for COMPLEMENT C1 INHIBITOR PROTEIN. Type I hereditary angioedema is associated with reduced serum levels of complement C1 inhibitor protein. Type II hereditary angioedema is associated with the production of a non-functional complement C1 inhibitor protein.
Hereditary conditions that feature progressive visual loss in association with optic atrophy. Relatively common forms include autosomal dominant optic atrophy (OPTIC ATROPHY, AUTOSOMAL DOMINANT) and Leber hereditary optic atrophy (OPTIC ATROPHY, HEREDITARY, LEBER).
Hereditary inflammation conditions, characterized by recurrent episodes of systemic inflammation. Common symptoms include recurrent fever, rash, arthritis, fatigue, and secondary AMYLOIDOSIS. Hereditary autoinflammatory diseases are associated with mutations in genes involved in regulation of normal inflammatory process and are not caused by AUTOANTIBODIES, or antigen specific T-LYMPHOCYTES.
A form of hereditary angioedema that occurs in women and is precipitated or worsened by high ESTROGEN levels. It is associated with mutations in the gene for FACTOR XII that result in its increased activity.
Hearing, auditory perception, or audition is the ability to perceive sound by detecting vibrations, changes in the pressure of the surrounding medium through time, through an organ such as the ear. Sound may be heard through solid, liquid, or gaseous mat...
Of all the types of Dementia, Alzheimer's disease is the most common, affecting around 465,000 people in the UK. Neurons in the brain die, becuase 'plaques' and 'tangles' (mis-folded proteins) form in the brain. People with Al...
DNA sequencing is the process of determining the precise order of nucleotides within a DNA molecule. During DNA sequencing, the bases of a small fragment of DNA are sequentially identified from signals emitted as each fragment is re-synthesized from a ...
