Progressive Ataxia and Palatal Tremor: Think about POLG Mutations

Mongin, Marie; Delorme, Cecile; Lenglet, Timothee; Jardel, Claude; Vignal, Catherine; Roze, Emmanuel

Background: Progressive ataxia and palatal tremor (PAPT) can be observed in both acquired brainstem or cerebellar lesions and genetic disorders.

Phenomenology shown: PAPT due to mutation in POLG, the gene encoding the mitochondrial DNA polymerase.

Educational value: POLG mutation should be considered in patients with PAPT, particularly when additional clues such as a sensory neuronopathy or an ophthalmoplegia are present.
