摘要：
This study introduces a novel mouse model for hereditary sensory and autonomic neuropathy subtype 9 (HSAN9) caused by a TECPR2 mutation. The model exhibits significant neurodegenerative phenotypes, including altered gait and axonal dystrophy, indicating TECPR2's crucial role in neuronal health and endolysosomal function. The findings suggest that TECPR2 deficiency leads to impaired lysosomal degradation and neuroinflammation, highlighting potential therapeutic targets for neurodegenerative diseases.
