ATXN8
protein-codingataxin 8
Gene summary
Spinocerebellar ataxia-8 (SCA8; {608768}) is a neurodegenerative disorder caused by a CTG/CAG trinucleotide repeat expansion on chromosome 13q21 (see {603680.0001} and {613289.0001}). Two genes span the CTG/CAG repeat and are expressed in opposite directions: ATXN8, which encodes a nearly pure polyglutamine expansion protein in the CAG direction, and ATXN8OS ({603680}), which, when transcribed, produces a noncoding CUG expansion RNA ({2:Moseley et al., 2006}).[supplied by OMIM, Mar 2010]

Rationale: Genetic knowledge may be beneficial related to issues such as selection of optimal supportive care, informed medical decision-making, prognostic considerations, and avoidance of unnecessary testing
Comments: The causative expansion variant is located in both the ATXN8OS 3' UTR and a polyglutamine ORF in ATXN8

ClinVar Variants & Pathogenicity by Type
Statistics based on transcript . Only rare variants are included.
We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.
Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.
