Any autosomal recessive cerebellar ataxia in which the cause of the disease is a mutation in the ANO10 gene.
Features include always present findings: Shrinkage of the cerebellum (cerebellar atrophy), Dysarthria, Gait ataxia, and Limb ataxia and others; and common findings: Pes cavus, Downbeat nystagmus, Tortuosity of conjunctival vessels, and Hypermetric saccades. 19 total HPO annotations.
Organ System | Phenotype Count | Example Features |

Brain and nerves | 9 | Truncal ataxia, Babinski sign, Dysarthria |
ANO10 encodes anoctamin 10 (660 aa). Does not exhibit calcium-activated chloride channel (CaCC) activity. Can inhibit the activity of ANO1 Highest expression in Cells Cultured fibroblasts (26.6 TPM) and Artery Tibial (25.0 TPM).
Autosomal recessive spinocerebellar ataxia 10 is caused by mutations in the ANO10 gene on chromosome 3.
ANO10 is classified as a druggable target (Transporter category) with score 0.0.
Genetic testing for ANO10 is available. Testing is considered confirmatory for diagnosis.
Phenotype severity distribution: 8 always present features, 4 common features.
Estimated prevalence: <1 in 1,000,000 (VERY_RARE).
1 clinical trial registered, 1 recruiting. Interventions under study include other interventions. Research is primarily sponsored by academic and government institutions.
6 publications have been identified in PubMed for autosomal recessive spinocerebellar ataxia 10. Research spans Review / Meta-Analysis (67%), Case Report / Case Series (17%), and Basic Science / Preclinical (17%).
