Autosomal recessive cerebellar ataxias (ARCA) are a heterogeneous group of rare neurological disorders involving both the central and peripheral nervous system (and in some cases other systems and organs), and characterized by degeneration or abnormal development of the cerebellum and spinal cord and, in most cases, early onset occurring before the age of 20 years.
Estimated prevalence: 1-9 in 100,000 (Uncommon).
2 clinical trials registered, 2 recruiting. Interventions under study include other interventions and gene therapy. Pipeline includes 1 NA. Research is primarily sponsored by academic and government institutions.
19 publications have been identified in PubMed for autosomal recessive cerebellar ataxia. Research spans Case Report / Case Series (37%), Basic Science / Preclinical (21%), and Review / Meta-Analysis (16%).
