Cacna1G 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.
CACNA1G (Calcium Voltage-Gated Channel Subunit Alpha1 G) encodes the α1G subunit of voltage-gated calcium channels, forming the pore of the T-type (CaV3.1) calcium channel.

The CACNA1G gene encodes the α1G subunit that forms the pore of the T-type (low-voltage activated) calcium channel (CaV3.1). T-type channels are characterized by:
T-type channels play critical roles in:
| Disease | Association Type | Key Evidence |
|---|---|---|
| Childhood Absence Epilepsy | Causative | CACNA1G mutations cause childhood absence epilepsy (EA9) |
| Spinocerebellar Ataxia | Causative | CACNA1G mutations cause SCA42 |
| Parkinson's Disease | Risk Modulator | Altered T-type channel function in PD substantia nigra |
| Alzheimer's Disease | Risk Modulator | Contributes to thalamic calcium dysregulation |
| Bipolar Disorder | Risk Modifier | GWAS signals implicate CACNA1G variants |
CACNA1G shows region-specific expression:
T-type calcium channels are established drug targets:
| Drug/Compound | Type | Status | Notes |
|---|---|---|---|
| Ethosuximide | Small molecule | Approved (absence seizures) | First-line treatment for absence epilepsy |
| Valproic acid | Small molecule | Approved (epilepsy) | Broad-spectrum antiepileptic |
| Zonisamide | Small molecule | Approved (epilepsy) | Blocks T-type channels |
| Pentobarbital | Small molecule | Approved (anesthesia) | Enhances GABA, blocks T-type |
