Perry Disease: Expanding the Genetic Basis

Abstract

AbstractBackgroundPerry disease (or Perry syndrome [PS]) is a hereditary neurodegenerative disorder inevitably leading to death within few years from onset. All previous cases with pathological confirmation were caused by mutations within the cytoskeleton‐associated protein glycine‐rich (CAP‐Gly) domain of the DCTN1 gene.ObjectivesThis paper presents the first clinicopathological report of PS due to a novel DCTN1 mutation outside the CAP‐Gly domain.MethodsClinical and pathological features of the new variant carrier are compared with another recently deceased PS case with a well‐known pathogenic DCTN1 mutation and other reported cases.Results and ConclusionsWe report a novel DCTN1 mutation outside the CAP‐Gly domain that we demonstrated to be pathogenic based on clinical and autopsy findings.
