Abstract

Neurodevelopmental disorders with early-onset parkinsonism have diverse genetic aetiologies and can mimic Parkinson's disease. We report the clinical evaluation and neuroimaging studies of a woman with intellectual disability and levodopa-responsive akinetic rigid parkinsonism. Whole-genome sequencing of family trio identified a de novo missense variant in PPP2R5D in the proband.

Keywords: Neurogenetics; PPP2R5D; Parkinsonism.
