DNAJC19 and cerebellar ataxia: Mutations in DNAJC19 were related to DCM and cerebellar ataxia (DCMA) syndrome, a novel autosomal recessive syndrome characterized by early-onset DCM with conduction defects, non-progressive cerebellar ataxia, testicular dysgenesis, growth failure, mild developmental delay, and 3-methylglutaconic aciduria, with or without sensorineural hearing loss and basal ganglia lesions (250–255).
