Chchd10 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.
CHCHD10 (Coiled-Coil-Helix-Coiled-Coil-Helix Domain Containing 10) is a gene located on chromosome 22q11.23 that encodes a mitochondrial protein essential for mitochondrial DNA maintenance, cristae organization, and neuronal survival 1. Mutations in CHCHD10 are associated with amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), mitochondrial myopathy, and a novel syndrome combining ALS with sensory ataxia 2.

The CHCHD10 protein is a small mitochondrial protein (182 amino acids) characterized by:
CHCHD10 plays a critical role in stabilizing mitochondrial DNA (mtDNA) nucleoids and maintaining mtDNA copy number. It interacts with mitochondrial transcription factor A (TFAM) to facilitate mtDNA packaging and replication 4.
As a Fe-S cluster binding protein, CHCHD10 participates in the mitochondrial Fe-S cluster assembly (ISCU) pathway, which is essential for the maturation of iron-sulfur proteins involved in oxidative phosphorylation (Complex I, II, III) 5.
CHCHD10 directly interacts with key components of the electron transport chain:
CHCHD10 shows high expression in:
CHCHD10 mutations cause a distinct form of autosomal dominant ALS (ALS15) characterized by:
The most common pathogenic variants include:
| Mutation | Type | Effect |
|---|---|---|
| S59L | Missense | Loss of mitochondrial function |
| R15L | Missense | Impaired Fe-S cluster assembly |
| G66V | Missense | Defective mtDNA maintenance |
| P34S | Missense | Reduced protein stability |
CHCHD10 mutations can cause FTD with or without ALS, particularly affecting:
Homozygous or compound heterozygous CHCHD10 mutations cause mitochondrial myopathy with:
A novel phenotype combining:
CHCHD10 mutations lead to:
Impaired Fe-S cluster assembly causes:
Motor neurons are particularly vulnerable due to:
