these findings demonstrated that the SNPs in the CACNA 1A, CACNA 1C, and CACNA 1H genes were involved in the pathophysiology of DPN. In addition, polymorphisms in the CACNA 1A, CACNA 1C, and CACNA 1H genes and their interactions also had effects on diabetic peripheral neuropathy (DPN) .

Here we show that T-type channels Cav3.1 and Cav3.2 are present in the lung and PASMCs from iPAH patients and control subjects. The blockade of T-type channels by the specific blocker, TTA-A2, prevents cell cycle progression and PASMCs growth
In gastric cancer, expression of all the CACNA (1G, 1H, 1I) genes was associated with overall survival (OS) among stage I-IV patients. By combining the three potential biomarkers, a TTCC signature was developed, which retained a significant association with OS both in stage IV and stage I-III patients. Alterations in CACNA gene expression are linked to tumour prognosis.
Our data establish Stac1 as an important modulator of T-type channel expression and provide new insights into the molecular mechanisms underlying the trafficking of T-type channels to the plasma membrane.
CACNA1H variant is associated with differential antiepileptic drug response in childhood absence epilepsy.
There is a direct link between CACNA1H(M1549V) mutation and an increased aldosterone production. This suggests that calcium channel blockers may be beneficial in the treatment of a subset of patients with primary aldosteronism.
CACNA1H might be a susceptibility gene predisposing to PA with different phenotypic presentations, opening new perspectives for genetic diagnosis and management of patients with PA.
modulation of N-linked glycosylation of hCav3.2 channels may play an important physiological role
heterozygous mutations identified in a pediatric patient with chronic pain and absence seizures result in loss of channel function, with significantly smaller current densities across a wide range of voltages when co-expressed in tsA-201 cells.
CaV3.1, CaV3.2 and CaV3.3 channels, are best recognized for their negative voltage of activation and inactivation thresholds that allow them to operate near the resting membrane potential of neurons.
Study revealed no association between the 15 tagSNPs of CACNA1A, 1C, and 1H and antiepileptic drug efficacy in the Chinese Han epileptic population; the TAGAA haplotype of CACNA1A may be a risk factor for drug resistance

N-linked glycosylation of Cav3.2 not only controls surface expression.
The purinergic channel pannexin1, the ATP-gated purinergic receptor P2 x 7R and the low voltage transiently opened T-type calcium channel CaV3.2-1 all reside in close proximity to beta3 integrin attachment foci on osteocyte processes, suggesting a specialized mechanotransduction complex at these sites.
In Cav3.2-/- mice NO levels increased significantly with age. Cav3.2-deficient mice develop less age-dependent endothelial dysfunction.

This study found that expressions of Cav3.2 and IGF-1R, and their colocalization were not increased in DRGs of mice following axotomy. In addition, Cav3.2 or IGF-1R subpopulation neurons did not acquire significant switch in expression phenotype after sciatic nerve axotomy.
Sensitization was relieved by pharmacological block of TRPV1 afferents, but not of myelinated neurons. In spinal cord slice recordings, we could optogenetically trigger an activity-dependent potentiation of presynaptic neurotransmission in the spinal dorsal horn that relied on Cav3.2 channel activity. This neuronal-activity-induced USP5 upregulation may underlie a protective, transient sensitization of the pain pathway.

This gene encodes a T-type member of the alpha-1 subunit family, a protein in the voltage-dependent calcium channel complex. Calcium channels mediate the influx of calcium ions into the cell upon membrane polarization and consist of a complex of alpha-1, alpha-2/delta, beta, and gamma subunits in a 1:1:1:1 ratio. The alpha-1 subunit has 24 transmembrane segments and forms the pore through which ions pass into the cell. There are multiple isoforms of each of the proteins in the complex, either encoded by different genes or the result of alternative splicing of transcripts. Alternate transcriptional splice variants, encoding different isoforms, have been characterized for the gene described here. Studies suggest certain mutations in this gene lead to childhood absence epilepsy (CAE).
