POLG2 encodes the accessory subunit B of DNA polymerase gamma, which enhances the processivity and fidelity of the catalytic subunit. POLG2 binds DNA and increases the affinity of POLG for the template. The accessory subunit also helps stabilize the enzyme and is essential for efficient mtDNA replication.
Expressed in tissues with high mitochondrial requirements. In the brain, expressed in neurons throughout the CNS.
| Disease | Variants | Inheritance | Mechanism |
|---|---|---|---|
| PEO | R369G, D475N | Autosomal dominant | Multiple mtDNA deletions |
| Sensory Ataxic Neuropathy | Various | Autosomal recessive | Severe mtDNA depletion |
