Spinocerebellar ataxia type 1 - Wikipedi

Spinocerebellar ataxia is a genetic disorder affects normal functioning of the central nervous system, mainly characterized by walking abnormality. The patient is having coordination problem with hand and legs. In the later stage it also affects speech, visual power and other sensory and reflex actions. Image 1: Spinocerebellar ataxia. Types What is spinocerebellar ataxia type 1? Spinocerebellar ataxia type 1 (SCA1) is one specific type of ataxia among a group of inherited diseases of the central nervous system. In SCA1, genetic defects lead to impairment of specific nerve fibers carrying messages to and from the brain, resulting in degeneration of the cerebellum (the coordinatio Ranum LP, Lundgren JK, Schut LJ, et al. Spinocerebellar ataxia type 1 and Machado-Joseph disease: incidence of CAG expansions among adult-onset ataxia patients from 311 families with dominant, recessive, or sporadic ataxia

Spinocerebellar ataxia (SCA) is a form of genetically inherited disorder that is characterized by abnormalities in the person's brain functioning. The disorder represents a varied group of related disorders and is commonly inherited as a dominant trait, meaning that people who carry one of the various different gene mutations are not affected. Ataxia with Oculomotor Apraxia Type 1 and Type 2 (AOA1 and AOA2) have also been identified. What is Sporadic Ataxia? There is a large group of people who have symptoms of Ataxia that usually begin in adulthood and who have no known family history of the disease. This is called Sporadic Ataxia and can be difficult to diagnose Spinocerebellar ataxia (SCA) is a term referring to a group of hereditary ataxias that are characterized by degenerative changes in the part of the brain related to the movement control (cerebellum), and sometimes in the spinal cord

Autosomal recessive cerebellar ataxia type 1 (ARCA1) is a condition characterized by progressive problems with movement due to a loss (atrophy) of nerve cells in the part of the brain that coordinates movement (the cerebellum)

Spinocerebellar ataxia type 1 (SCA1) was the first autosomal dominant cerebellar ataxia (ADCA) to be genetically characterized (Orr et al., 1993). ADCAs are a clinically and genetically heterogeneous group of neurodegenerative disorders primarily characterized by imbalance, progressive gait and limb ataxia, and dysarthria, which have been. In most of these disorders, we see some type of toxic protein accumulating in the brain. It's as if the brain's garbage disposal system is blocked, letting the waste pile up.

The first gene mutation causing SCA was identified in 1992 and named Spinocerebellar Ataxia Type 1 (SCA1). As further genes were identified they were given numerically sequential names (SCA2, SCA3, etc) and so far there have been at least 29 gene mutations found Movement Disorders Vol. 23, No. 6, 2008, pp. 899-903 Ó 2008 Movement Disorder Society Brief Reports with mild to moderate cerebellar deficit, GM and WM Brain Structural Damage in volume loss and CSF volume increase are confined to the Spinocerebellar Ataxia Type 2

Spinocerebellar Ataxia Types. Like the rest of the spinocerebellar ataxia types, SCA Type 1 is not sex-specific, meaning both males and females have an equal chance of inheriting it. It only takes one parent with the defective gene to pass down the disease.

Machado-Joseph Disease (MJD) or spinocerebellar ataxia type 3 (SCA3) is the most common spinocerebellar ataxia worldwide. MJD can have widespread symptoms due to the the many anatomical structures that can be affected. These structures include: Of the aforementioned structures, the common finding is degeneration Expansion of a polyglutamine repeat within the spinocerebellar ataxia type 1 (SCA1)-encoded protein, ataxin-1, causes the neurodegenerative disease, SCA1. Animal models have been generated that recapitulate many of the aspects of SCA1 pathogenesis. These provide a good example of how animal models. Spinocerebellar Ataxia Type 2. Examination may reveal very mild dysarthria, slowed, hypometric or totally absent saccades, supranuclear ophthalmoplegia, fasiculations in the face and tongue, dystonia and chorea and segmental or total loss of reflexes.
