Nhlrc2 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
The NHLRC2 gene (NHL Repeat Containing 2) encodes a protein containing NHL (NHL-1, HTP-1, and Let-23) repeats. NHLRC2 is a relatively uncharacterized protein implicated in autophagy, protein quality control, and more recently in a spectrum of neurodegenerative disorders. Biallelic mutations cause a novel neurodevelopmental disorder with seizures and ataxia.

NHLRC2 is a 395-amino acid protein containing:
- NHL repeat domains (beta-propeller structure)
- Multiple protein-protein interaction motifs
- Potential phosphorylation sites
NHLRC2 functions in cellular protein homeostasis:
- Autophagy Regulation: Modulates autophagic flux
- Protein Quality Control: Assists in clearance of misfolded proteins
- Stress Response: Responds to cellular stress conditions
- Cytoskeletal Interactions: May affect cellular architecture
NHLRC2 is expressed in most tissues:
- Brain (neurons and glia)
- Heart
- Lung
- Kidney
- Liver
In the brain:
- Cerebral cortex
- Cerebellum
- Brainstem
¶ Neurodevelopmental Disorder with Ataxia and Seizures (NEDCAS)
- Biallelic NHLRC2 mutations cause NEDCAS
- Early-onset seizures, ataxia, developmental delay
- Brain malformations observed
- PMID:30251358, PMID:32465690
- Altered expression in some cancers
- Potential tumor suppressor role
- Autophagy Modulators: Enhance aggregate clearance
- Antiseizure Drugs: For epilepsy management
- Gene Therapy: AAV-delivered NHLRC2
- Protein Folding Helpers: Pharmacological chaperones
- Knockout mice: Viable with neurological phenotypes
- Zebrafish: Developmental defects
- Cellular models: Autophagy impairment
The study of Nhlrc2 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
