This disease has characteristics of progressive cerebellar ataxia with pyramidal and spinal cord dysfunction, associated with distinctive MRI anomalies and increased lactate in the abnormal white matter. Onset occurs in early childhood. Epilepsy and cognitive decline have also been described. The syndrome is caused by mutations in the DARS2 gene, which encodes mitochondrial aspartyl-tRNA synthetase. Transmission is autosomal recessive.
