The syndrome of sensory ataxic neuropathy with dysarthria and ophthalmoplegia (SANDO), defined genetically by mutations of the gene for the mitochondrial DNA polymerase-γ, POLG, was first described in 1997 (1). Since then, several case reports with various POLG, or more rarely PEO1, mutations have been published (2-4), some specifically addressing muscle and nerve pathology (1, 3), nerve electrophysiology (5), or radiological aspects (4, 6, 7).
