Overview
VPS13C (Vacuolar Protein Sorting 13 Homolog C) is a member of the VPS13 family of lipid transfer proteins that plays critical roles in endolysosomal trafficking, lipid homeostasis, and [mitophagy](/mechanisms/autophagy-lysosomal-pathway)<sup>[1]</sup>. Loss-of-function mutations in VPS13C cause autosomal recessive early-onset Parkinson's disease (PARK23), highlighting its essential role in dopaminergic neuron survival<sup>[2]</sup>. PMID: 39475571
Gene Structure
The VPS13C gene spans approximately 140 kb on chromosome 15q22.31 and contains: PMID: 26250687
- 77 exons encoding a 3,589 amino acid protein
- Multiple transcript variants with tissue-specific expression
- Highly conserved regions shared with other VPS13 family members PMID: 29874566
Expression Pattern
VPS13C is widely expressed with highest levels in:
- Brain: Particularly in substantia nigra dopaminergic [neurons](/entities/neurons) PMID: 32755557
- Pancreas: Beta cells and exocrine tissue
- Testis: High expression levels
Protein Function
Lipid Transfer
VPS13C functions as a lipid transfer protein that shuttles lipids between organelles<sup>[3]</sup>:
- ER-mitochondria contacts: Transfers phospholipids for mitochondrial membrane maintenance
- ER-lipid droplet contacts: Regulates lipid storage and mobilization
- ER-endolysosomal contacts: Supports endolysosomal membrane homeostasis
Mitophagy Regulation
VPS13C plays a critical role in [mitochondrial quality control](/mechanisms/mitochondrial-dysfunction-pathway)<sup>[4]</sup>:
- Recruitment to damaged mitochondria: Responds to loss of mitochondrial membrane potential
- Interaction with PINK1/Parkin: Works in concert with the canonical mitophagy pathway
- Lipid supply for autophagosome formation: Provides membrane lipids for autophagosome biogenesis
Endolysosomal Function
VPS13C maintains endolysosomal health through<sup>[5]</sup>:
- Lysosomal membrane integrity: Ensures proper lysosomal function
- Endosome maturation: Supports trafficking through the endolysosomal system
- Lysosomal pH regulation: Contributes to acidification and enzyme activity
Disease Associations
Parkinson's Disease (PARK23)
Biallelic loss-of-function mutations in VPS13C cause early-onset Parkinson's disease<sup>[6]</sup>:
Clinical Features
- Age at onset: 20-40 years (early-onset)
- Motor symptoms: Tremor, bradykinesia, rigidity
- Rapid progression: Faster disease course than typical PD
- Good levodopa response: Excellent initial response to dopamine replacement
- Non-motor features: Cognitive decline may occur earlier
Pathogenic Mutations
| Mutation | Type | Population | Effect |
|----------|------|------------|--------|
| c.2382+1G>A | Splice site | European | Exon skipping |
| c.7166C>T | Nonsense | European | Truncation |
| c.2869dup | Frameshift | Middle Eastern | Premature stop |
| c.4612C>T | Nonsense | Various | p.Arg1538* |
Pathological Findings
- Dopaminergic neuron loss: Marked degeneration of substantia nigra
- Lewy body pathology: Some cases show [α-synuclein](/mechanisms/alpha-synuclein-aggregation-pathway) inclusions
- Mitochondrial abnormalities: Accumulation of damaged mitochondria
Mechanistic Links to PD
VPS13C deficiency causes PD through multiple converging pathways<sup>[7]</sup>:
Interacting Proteins
VPS13C interacts with several proteins involved in PD pathogenesis<sup>[8]</sup>:
| Partner | Function | PD Relevance |
|---------|----------|--------------|
| PINK1 | Mitophagy initiation | PARK6 gene |
| Parkin | Ubiquitin ligase | PARK2 gene |
| DJ-1 | Oxidative stress response | PARK7 gene |
| GBA1 | Lysosomal enzyme | PD risk factor |
| LRRK2 | Kinase signaling | PARK8 gene |
Animal Models
Knockout Mice
VPS13C knockout mice show<sup>[9]</sup>:
- Motor deficits at 12 months
- Dopaminergic neuron loss in substantia nigra
- Mitochondrial abnormalities in neurons
- Enhanced sensitivity to MPTP toxicity
Cellular Models
Patient-derived iPSC neurons reveal<sup>[10]</sup>:
- Impaired mitophagy flux
- Accumulation of PINK1 on mitochondria
- Increased oxidative stress
- Reduced survival of dopaminergic neurons
Therapeutic Implications
Targeting VPS13C Pathway
Potential therapeutic approaches<sup>[11]</sup>:
| Strategy | Approach | Status |
|----------|----------|--------|
| Gene therapy | AAV-mediated VPS13C delivery | Preclinical |
| Enhance mitophagy | Small molecule activators | Research |
| Bypass pathway | Alternative lipid transfer | Conceptual |
| Symptomatic | Levodopa, dopamine agonists | Clinical use |
Biomarker Potential
VPS13C-related biomarkers may include:
- Circulating lipids: Altered lipid profiles in PD patients
- Mitochondrial markers: PINK1 levels, mitophagy markers
- Imaging: Mitochondrial function by PET
Genetic Testing
VPS13C sequencing is recommended for<sup>[12]</sup>:
- Early-onset PD (<40 years) with autosomal recessive pattern
- PD patients with affected siblings
- Consanguineous families with PD
- Cases with rapid progression
