Insights
Perry disease, a fatal neurodegenerative disorder, is linked to novel DCTN1 gene mutations outside the typical CAP-Gly domain. This study details the first clinicopathological findings of such a case.
Area of Science:
- Genetics
- Neuroscience
- Pathology
Background:
- Perry disease (PS) is a fatal, hereditary neurodegenerative disorder.
- Previously confirmed PS cases involved mutations in the CAP-Gly domain of the DCTN1 gene.
Purpose of the Study:
- To report the first clinicopathological case of Perry disease caused by a novel DCTN1 mutation outside the CAP-Gly domain.
- To compare the clinical and pathological features of this new variant with previously reported cases.
Main Methods:
- Clinicopathological examination of a novel Perry disease case.
- Genetic analysis to identify DCTN1 mutation.
- Comparative analysis with existing Perry disease case reports.
Main Results:
- Identification of a novel pathogenic DCTN1 mutation outside the CAP-Gly domain in a Perry disease patient.
- Detailed clinical and autopsy findings of the affected individual.
- Comparison highlighting similarities and differences with known Perry disease variants.
Conclusions:
- The DCTN1 gene is implicated in Perry disease beyond the CAP-Gly domain.
- This finding expands the genetic understanding of Perry disease.
- Further research into DCTN1 mutations is warranted for Perry disease diagnosis and treatment.
Background:
Perry 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.
Objectives:
This paper presents the first clinicopathological report of PS due to a novel DCTN1 mutation outside the CAP-Gly domain.
Methods:
Clinical 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 Conclusions:
We report a novel DCTN1 mutation outside the CAP-Gly domain that we demonstrated to be pathogenic based on clinical and autopsy findings.
