Summary: 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 40-83 CAG repeats, compared to 6-39 in the normal allele, and is associated with spinocerebellar ataxia type 1 (SCA1). Alternative splicing results in multiple transcript variants, with one variant encoding multiple distinct proteins, ATXN1 and Alt-ATXN1, due to the use of overlapping alternate reading frames.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

See identical proteins and their annotated locations for NP_000323.2

Status: REVIEWED

Description

Transcript Variant: This variant (1) encodes multiple distinct proteins due to the use of alternative translation initiation codons. The longer 815 aa protein (ATXN1, PMID:23705062) represents the canonical protein, while a shorter protein (Alt-ATXN1, PMID:23705062) that uses a different reading frame has also been described. This RefSeq represents the longer protein, ATXN1. Variant 2 also encodes ATXN1.

The longer, 815 aa protein represents the canonical protein, while a shorter 185 aa protein(Alt-ATXN1, PMID:23760502) that uses a different reading frame has also been described. Alt-ATXN1 does not share structural similarity to the ATXN1, but has been shown to interact with the ATXN1. This RefSeq represents the shorter protein, Alt-ATXN1.
