| Ataxia - adult onset v0.82 | SCA8 |
Bryony Thompson STR: SCA8 was added STR: SCA8 was added to Ataxia - adult onset. Sources: Expert list STR tags were added to STR: SCA8. Mode of inheritance for STR: SCA8 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for STR: SCA8 were set to 20301445 Phenotypes for STR: SCA8 were set to Spinocerebellar ataxia 8 MIM#608768 Review for STR: SCA8 was set to GREEN STR: SCA8 was marked as clinically relevant Added comment: NR_002717.2:n.1073CTA[X]1103CTG[X] ATXN8 (CAG)n(TAG)n vs ATXN8OS on opposite strand (CTA)n(CTG)n Both toxic RNA and toxic protein gain of function mechanisms likely contribute to disease mechanism Normal alleles: 15-50 combined (CTA·TAG)n(CTG·CAG)n repeats Alleles of questionable significance: 50-70 repeats. Reduced penetrance allele size: found for (CTA·TAG)n(CTG·CAG)n repeats of all sizes Higher penetrance allele size: ≥80 (CTA·TAG)n(CTG·CAG)n repeats most often seen in individuals with ataxia; however, repeat sizes ranging from 71 to more than 1300 repeats have been found both in individuals who develop ataxia and in those who do not.

Bryony Thompson gene: ATXN8 was added gene: ATXN8 was added to Ataxia - adult onset. Sources: Expert list STR tags were added to gene: ATXN8. Mode of inheritance for gene: ATXN8 was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for gene: ATXN8 were set to 16804541 Phenotypes for gene: ATXN8 were set to Spinocerebellar ataxia 8 MIM#608768 Mode of pathogenicity for gene: ATXN8 was set to Other Review for gene: ATXN8 was set to GREEN Added comment: Adult onset cerebellar ataxia caused by expanded CAG repeat. Normal alleles contain 15 to 50 repeats, and pathogenic alleles contain 71 to 1,300 repeats. Sources: Expert list |
