Perry Syndrome: A Distinctive Type of TDP-43 Proteinopathy.

ABSTRACT: Perry syndrome is a rare atypical parkinsonism with depression, apathy, weight loss, and central hypoventilation caused by mutations in dynactin p150glued (DCTN1). A rare distal hereditary motor neuropathy, HMN7B, also has mutations in DCTN1. Perry syndrome has TAR DNA-binding protein of 43 kDa (TDP-43) inclusions as a defining feature. Other TDP-43 proteinopathies include amyotrophic lateral sclerosis (ALS) and frontotemporal lobar degeneration (FTLD) with and without motor neuron disease (FTLD-MND). TDP-43 forms aggregates in neuronal cytoplasmic inclusions (NCIs), neuronal intranuclear inclusions, dystrophic neurites (DNs), as well as axonal spheroids, oligodendroglial cytoplasmic inclusions, and perivascular astrocytic inclusions (PVIs). We performed semiquantitative assessment of thes
