Abstract
The G2019S leucine-rich repeat kinase 2 gene (LRRK2) mutation has been identified in a significant proportion of familial and sporadic cases of Parkinson’s disease (PD). Until now, information on the neuropathological changes associated with the G2019S LRRK2 mutation has been sparse. We report a 77-year-old patient who presented with a 14 year history of PD but, unexpectedly, histopathological examination disclosed mild neuronal loss in the substantia nigra without α-synuclein, tau or ubiquitin cytoplasmic inclusions. A G2019S LRRK2 mutation was eventually detected. The present case confirms that clinical PD caused by G2019S mutations can be associated with non-specific nigral degeneration without Lewy bodies.
