Summaries for CACNB4 Gene

Entrez Gene Summary for CACNB4 Gene

  • This gene encodes a member of the beta subunit family of voltage-dependent calcium channel complex proteins. 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. Various versions of each of these subunits exist, either expressed from similar genes or the result of alternative splicing. The protein encoded by this locus plays an important role in calcium channel function by modulating G protein inhibition, increasing peak calcium current, controlling the alpha-1 subunit membrane targeting and shifting the voltage dependence of activation and inactivation. Certain mutations in this gene have been associated with idiopathic generalized epilepsy (IGE) and juvenile myoclonic epilepsy (JME). Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

GeneCards Summary for CACNB4 Gene

CACNB4 (Calcium Channel, Voltage-Dependent, Beta 4 Subunit) is a Protein Coding gene. Diseases associated with CACNB4 include epilepsy, idiopathic generalized 9 and episodic ataxia, type 5. Among its related pathways are MAPK signaling pathway and L1CAM interactions. GO annotations related to this gene include voltage-gated calcium channel activity and high voltage-gated calcium channel activity. An important paralog of this gene is CACNB3.

  • Epilepsy, idiopathic generalized 9 (EIG9) [MIM:607682]: A disorder characterized by recurring generalized seizures in the absence of detectable brain lesions and/or metabolic abnormalities. Generalized seizures arise diffusely and simultaneously from both hemispheres of the brain. {ECO:0000269 PubMed:10762541}. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
  • Juvenile myoclonic epilepsy 6 (EJM6) [MIM:607682]: A subtype of idiopathic generalized epilepsy. Patients have afebrile seizures only, with onset in adolescence (rather than in childhood) and myoclonic jerks which usually occur after awakening and are triggered by sleep deprivation and fatigue. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
  • Episodic ataxia 5 (EA5) [MIM:613855]: A disorder characterized by episodes of vertigo and ataxia that last for several hours. Interictal examination show spontaneous downbeat and gaze-evoked nystagmus, mild dysarthria and truncal ataxia. {ECO:0000269 PubMed:10762541}. Note=The disease is caused by mutations affecting the gene represented in this entry.
