Bryony Thompson STR: SCA_THAP11_CAG was added STR: SCA_THAP11_CAG was added to Repeat Disorders. Sources: Other Mode of inheritance for STR: SCA_THAP11_CAG was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted Publications for STR: SCA_THAP11_CAG were set to 15368101; 24677642; 34165550; 38113319 Phenotypes for STR: SCA_THAP11_CAG were set to autosomal dominant cerebellar ataxia MONDO:0020380 Review for STR: SCA_THAP11_CAG was set to AMBER Added comment: 7 individuals from 2 Chinese families with SCA (1 was pre-ataxic) and a THAP11 CAG (polyQ) expansion. 45 repeats was the lowest number of repeats in an affected individual. A 46/29 CAG THAP11 genotype has also been identified in an individual with ataxia of European ancestry, that also had a CACNA1A pathogenic expansion which causes SCA6. Analysis of the 1000 genomes cohort (n=2504), suggests a normal range between 19-39. Also, a supporting mouse model and functional assays support a toxic aggregation mechanism of disease. Further probands/families are required to confirm the gene-disease association. Sources: Other |
