Quick Reference

A mitochondrial disorder that causes clinically variable systemic effects. It is phenotypically similar to autosomal recessive progressive external ophthalmoplegia and the mitochondrial neurogastrointestinal encephalopathy syndrome. Sensory ataxic neuropathy, dysarthria, and ophthalmoparesis (SANDO) is caused by mutation in the nuclear gene that encodes DNA polymerase-γ or by mutation in the gene for twinkle.
