特徴

• The autosomal dominant cerebellar ataxias (ADCA) are a heterogeneous group of neurodegenerative disorders characterized by progressive degeneration of the cerebellum, brain stem and spinal cord.
• Clinically, ADCA has been divided into three groups: ADCA types I-III.
• ADCAI is genetically heterogeneous, with five genetic loci, designated spinocerebellar ataxia (SCA) 1, 2, 3, 4 and 6, being assigned to five different chromosomes.
• ADCAII, which always presents with retinal degeneration (SCA7), and ADCAIII often referred to as the `pure' cerebellar syndrome (SCA5), are most likely homogeneous disorders.
• Several SCA genes have been cloned and shown to contain CAG repeats in their coding regions.
• ADCA is caused by the expansion of the CAG repeats, producing an elongated polyglutamine tract in the corresponding protein.
• The expanded repeats are variable in size and unstable, usually increasing in size when transmitted to successive generations.
• The function of the ataxins is not known.
• This locus has been mapped to chromosome 6, and it has been determined that the diseased allele contains 41-81 CAG repeats, compared to 6-39 in the normal allele, and is associated with spinocerebellar ataxia type 1 (SCA1).
• At least two transcript variants encoding the same protein have been found for this gene.
• Applications:Suitable for use in Western Blot, Immunohistochemistry.
• Other applications not tested.
• Recommended Dilution:Western Blot: 1:500-1:2000Immunohistochemistry: 1:50-1:200Optimal dilutions to be determined by the researcher.
