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[1]. Loss-of-function mutations in VPS13C cause autosomal recessive early-onset Parkinson's disease (PARK23), highlighting its essential role in dopaminergic neuron survival[2].
The VPS13C gene spans approximately 140 kb on chromosome 15q22.31 and contains:
VPS13C is widely expressed with highest levels in:
VPS13C functions as a lipid transfer protein that shuttles lipids between organelles[3]:
VPS13C plays a critical role in mitochondrial quality control[4]:
VPS13C maintains endolysosomal health through[5]:
Biallelic loss-of-function mutations in VPS13C cause early-onset Parkinson's disease[6]:
| 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* |
